Mixed-Signal Oscilloscope
Channel Differences
See Also
Because both the "analog channels only" oscilloscopes (DSO models) and the mixed-signal oscilloscopes (MSO models) have analog channels, topics that describe analog channels refer to all oscilloscope models. Whenever a topic describes digital channels, that information applies only to the mixed-signal oscilloscope models.
· For more information on using the SICL, VISA, and VISA COM libraries in general, see the documentation that comes with the Keysight IO Libraries Suite.
· For information on controller PC interface configuration, see the documentation for the interface card used (for example, the Keysight 82350B GPIB interface).
· For information on oscilloscope front-panel operation, see the User's Guide. · For detailed connectivity information, refer to the Keysight Technologies

Command Differences From 7000B Series Oscilloscopes
New Commands
The Keysight InfiniiVision 3000 X-Series oscilloscopes command set is most closely related to the InfiniiVision 7000B Series oscilloscopes (and the 7000A Series, 6000 Series, and 54620/54640 Series oscilloscopes before them).
The main differences between the version 1.00 programming command set for the InfiniiVision 3000 X-Series oscilloscopes and the 6.10 programming command set for the InfiniiVision 7000B Series oscilloscopes are related to: · Built-in waveform generator (with Option WGN license). · Built-in demo signals (with Option EDU license that comes with the N6455A
Education Kit). · Reference waveforms (in place of trace memory). · Multiple serial decode waveforms. · Serial decode now available on 2-channel oscilloscopes. · Enhanced set of trigger types. · Additional measurements. · Different path name format for internal and USB storage device locations.

Basic Oscilloscope Program Structure / 64 Programming the Oscilloscope / 66 Other Ways of Sending Commands / 75
NOTE
This chapter gives you an overview of programming the 3000 X-Series oscilloscopes. It describes basic oscilloscope program structure and shows how to program the oscilloscope using a few simple examples. The getting started examples show how to send oscilloscope setup, data capture, and query commands, and they show how to read query results.
Language for Program Examples
The programming examples in this guide are written in Visual Basic using the Keysight VISA COM library.
63
3 Getting Started
Basic Oscilloscope Program Structure
The following figure shows the basic structure of every program you will write for the oscilloscope.
Initializing
To ensure consistent, repeatable performance, you need to start the program, controller, and oscilloscope in a known state. Without correct initialization, your program may run correctly in one instance and not in another. This might be due to changes made in configuration by previous program runs or from the front panel of the oscilloscope. · Program initialization defines and initializes variables, allocates memory, or
tests system configuration. · Controller initialization ensures that the interface to the oscilloscope is properly
set up and ready for data transfer. · Oscilloscope initialization sets the channel configuration, channel labels,
threshold voltages, trigger specification, trigger mode, timebase, and acquisition type.
Capturing Data
Once you initialize the oscilloscope, you can begin capturing data for analysis. Remember that while the oscilloscope is responding to commands from the controller, it is not performing acquisitions. Also, when you change the oscilloscope configuration, any data already captured will most likely be rendered. To collect data, you use the :DIGitize command. This command clears the waveform buffers and starts the acquisition process. Acquisition continues until acquisition memory is full, then stops. The acquired data is displayed by the oscilloscope, and the captured data can be measured, stored in acquisition memory in the oscilloscope, or transferred to the controller for further analysis. Any additional commands sent while :DIGitize is working are buffered until :DIGitize is complete.
64
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
Getting Started 3
You could also put the oscilloscope into run mode, then use a wait loop in your program to ensure that the oscilloscope has completed at least one acquisition before you make a measurement. Keysight does not recommend this because the needed length of the wait loop may vary, causing your program to fail. :DIGitize, on the other hand, ensures that data capture is complete. Also, :DIGitize, when complete, stops the acquisition process so that all measurements are on displayed data, not on a constantly changing data set.
Analyzing Captured Data
After the oscilloscope has completed an acquisition, you can find out more about the data, either by using the oscilloscope measurements or by transferring the data to the controller for manipulation by your program. Built-in measurements include: frequency, duty cycle, period, positive pulse width, and negative pulse width. Using the :WAVeform commands, you can transfer the data to your controller. You may want to display the data, compare it to a known good measurement, or simply check logic patterns at various time intervals in the acquisition.

Referencing the IO Library
No matter which instrument programming library you use (SICL, VISA, or VISA COM), you must reference the library from your program. In C/C++, you must tell the compiler where to find the include and library files (see the Keysight IO Libraries Suite documentation for more information). To reference the Keysight VISA COM library in Visual Basic for Applications (VBA, which comes with Microsoft Office products like Excel): 1 Choose Tools>References... from the main menu. 2 In the References dialog, check the "VISA COM 5.9 Type Library".

3 Click OK. To reference the Keysight VISA COM library in Microsoft Visual Basic 6.0: 1 Choose Project>References... from the main menu. 2 In the References dialog, check the "VISA COM 5.9 Type Library". 3 Click OK.
Opening the Oscilloscope Connection via the IO Library
PC controllers communicate with the oscilloscope by sending and receiving messages over a remote interface. Once you have opened a connection to the oscilloscope over the remote interface, programming instructions normally appear as ASCII character strings embedded inside write statements of the programing language. Read statements are used to read query responses from the oscilloscope. For example, when using the Keysight VISA COM library in Visual Basic (after opening the connection to the instrument using the ResourceManager object's Open method), the FormattedIO488 object's WriteString, WriteNumber, WriteList, or WriteIEEEBlock methods are used for sending commands and queries. After a query is sent, the response is read using the ReadString, ReadNumber, ReadList, or ReadIEEEBlock methods. The following Visual Basic statements open the connection and send a command that turns on the oscilloscope's label display.
Dim myMgr As VisaComLib.ResourceManager Dim myScope As VisaComLib.FormattedIO488
Set myMgr = New VisaComLib.ResourceManager Set myScope = New VisaComLib.FormattedIO488
' Open the connection to the oscilloscope. Get the VISA Address from the ' Keysight Connection Expert (installed with Keysight IO Libraries Suite ). Set myScope.IO = myMgr.Open("<VISA Address>")
' Send a command. myScope.WriteString ":DISPlay:LABel ON"
The ":DISPLAY:LABEL ON" in the above example is called a program message. Program messages are explained in more detail in "Program Message Syntax" on page 1165.
Initializing the Interface and the Oscilloscope
To make sure the bus and all appropriate interfaces are in a known state, begin every program with an initialization statement. When using the Keysight VISA COM library, you can use the resource session object's Clear method to clears the interface buffer:
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
67
3 Getting Started
NOTE
Dim myMgr As VisaComLib.ResourceManager Dim myScope As VisaComLib.FormattedIO488
Set myMgr = New VisaComLib.ResourceManager Set myScope = New VisaComLib.FormattedIO488
' Open the connection to the oscilloscope. Get the VISA Address from the ' Keysight Connection Expert (installed with Keysight IO Libraries Suite ). Set myScope.IO = myMgr.Open("<VISA Address>")
' Clear the interface buffer and set the interface timeout to 10 seconds . myScope.IO.Clear myScope.IO.Timeout = 10000
When you are using GPIB, CLEAR also resets the oscilloscope's parser. The parser is the program which reads in the instructions which you send it. After clearing the interface, initialize the instrument to a preset state:
myScope.WriteString "*RST"
Information for Initializing the Instrument
The actual commands and syntax for initializing the instrument are discussed in Chapter 5, "Common (*) Commands," starting on page 167. Refer to the Keysight IO Libraries Suite documentation for information on initializing the interface.
Using :AUToscale to Automate Oscilloscope Setup
The :AUToscale command performs a very useful function for unknown waveforms by setting up the vertical channel, time base, and trigger level of the instrument. The syntax for the autoscale command is:
myScope.WriteString ":AUToscale"
Using Other Oscilloscope Setup Commands
A typical oscilloscope setup would set the vertical range and offset voltage, the horizontal range, delay time, delay reference, trigger mode, trigger level, and slope. An example of the commands that might be sent to the oscilloscope are:
myScope.WriteString ":CHANnel1:PROBe 10" myScope.WriteString ":CHANnel1:RANGe 16" myScope.WriteString ":CHANnel1:OFFSet 1.00" myScope.WriteString ":TIMebase:MODE MAIN" myScope.WriteString ":TIMebase:RANGe 1E-3" myScope.WriteString ":TIMebase:DELay 100E-6"
68
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
Getting Started 3
Vertical is set to 16 V full-scale (2 V/div) with center of screen at 1 V and probe attenuation set to 10. This example sets the time base at 1 ms full-scale (100 ms/div) with a delay of 100 µs.
Example Oscilloscope Setup Code
This program demonstrates the basic command structure used to program the oscilloscope.
' Initialize the instrument interface to a known state. myScope.IO.Clear myScope.IO.Timeout = 10000 ' Set interface timeout to 10 seconds.
' Initialize the instrument to a preset state. myScope.WriteString "*RST"
' Set the time base mode to normal with the horizontal time at
' 50 ms/div with 0 s of delay referenced at the center of the
' graticule.
myScope.WriteString ":TIMebase:RANGe 5E-4" ' Time base to 50 us/div.
myScope.WriteString ":TIMebase:DELay 0"
' Delay to zero.
myScope.WriteString ":TIMebase:REFerence CENTer" ' Display ref. at

' Set the vertical range to 1.6 volts full scale with center screen
' at -0.4 volts with 10:1 probe attenuation and DC coupling.
myScope.WriteString ":CHANnel1:PROBe 10"
' Probe attenuation
' to 10:1.
myScope.WriteString ":CHANnel1:RANGe 1.6" ' Vertical range
' 1.6 V full scale.
myScope.WriteString ":CHANnel1:OFFSet -0.4" ' Offset to -0.4.
myScope.WriteString ":CHANnel1:COUPling DC" ' Coupling to DC.
' Configure the instrument to trigger at -0.4 volts with normal
' triggering.
myScope.WriteString ":TRIGger:SWEep NORMal" ' Normal triggering.
myScope.WriteString ":TRIGger:LEVel -0.4"
' Trigger level to -0.4.
myScope.WriteString ":TRIGger:SLOPe POSitive" ' Trigger on pos. slope.
' Configure the instrument for normal acquisition. myScope.WriteString ":ACQuire:TYPE NORMal" ' Normal acquisition.
Capturing Data with the :DIGitize Command
The :DIGitize command captures data that meets the specifications set up by the :ACQuire subsystem. When the digitize process is complete, the acquisition is stopped. The captured data can then be measured by the instrument or transferred to the controller for further analysis. The captured data consists of two parts: the waveform data record, and the preamble.
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
69
3 Getting Started
NOTE NOTE
Ensure New Data is Collected
When you change the oscilloscope configuration, the waveform buffers are cleared. Before doing a measurement, send the :DIGitize command to the oscilloscope to ensure new data has been collected.
When you send the :DIGitize command to the oscilloscope, the specified channel signal is digitized with the current :ACQuire parameters. To obtain waveform data, you must specify the :WAVeform parameters for the SOURce channel, the FORMat type, and the number of POINts prior to sending the :WAVeform:DATA? query.
Set :TIMebase:MODE to MAIN when using :DIGitize
:TIMebase:MODE must be set to MAIN to perform a :DIGitize command or to perform any :WAVeform subsystem query. A "Settings conflict" error message will be returned if these commands are executed when MODE is set to ROLL, XY, or WINDow (zoomed). Sending the *RST (reset) command will also set the time base mode to normal.
The number of data points comprising a waveform varies according to the number requested in the :ACQuire subsystem. The :ACQuire subsystem determines the number of data points, type of acquisition, and number of averages used by the :DIGitize command. This allows you to specify exactly what the digitized information contains. The following program example shows a typical setup:
myScope.WriteString ":ACQuire:TYPE AVERage" myScope.WriteString ":ACQuire:COMPlete 100" myScope.WriteString ":ACQuire:COUNt 8" myScope.WriteString ":DIGitize CHANnel1" myScope.WriteString ":WAVeform:SOURce CHANnel1" myScope.WriteString ":WAVeform:FORMat BYTE" myScope.WriteString ":WAVeform:POINts 500" myScope.WriteString ":WAVeform:DATA?"
This setup places the instrument into the averaged mode with eight averages. This means that when the :DIGitize command is received, the command will execute until the signal has been averaged at least eight times. After receiving the :WAVeform:DATA? query, the instrument will start passing the waveform information. Digitized waveforms are passed from the instrument to the controller by sending a numerical representation of each digitized point. The format of the numerical representation is controlled with the :WAVeform:FORMat command and may be selected as BYTE, WORD, or ASCii.
70
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
Getting Started 3
NOTE
The easiest method of transferring a digitized waveform depends on data structures, formatting available and I/O capabilities. You must scale the integers to determine the voltage value of each point. These integers are passed starting with the left most point on the instrument's display. For more information, see the waveform subsystem commands and corresponding program code examples in Chapter 32, ":WAVeform Commands," starting on page 983.
Aborting a Digitize Operation Over the Programming Interface
When using the programming interface, you can abort a digitize operation by sending a Device Clear over the bus (for example, myScope.IO.Clear).
Reading Query Responses from the Oscilloscope
After receiving a query (command header followed by a question mark), the instrument interrogates the requested function and places the answer in its output queue. The answer remains in the output queue until it is read or another command is issued. When read, the answer is transmitted across the interface to the designated listener (typically a controller). The statement for reading a query response message from an instrument's output queue typically has a format specification for handling the response message. When using the VISA COM library in Visual Basic, you use different read methods (ReadString, ReadNumber, ReadList, or ReadIEEEBlock) for the various query response formats. For example, to read the result of the query command :CHANnel1:COUPling? you would execute the statements:
myScope.WriteString ":CHANnel1:COUPling?" Dim strQueryResult As String strQueryResult = myScope.ReadString
This reads the current setting for the channel one coupling into the string variable strQueryResult. All results for queries (sent in one program message) must be read before another program message is sent. Sending another command before reading the result of the query clears the output buffer and the current response. This also causes an error to be placed in the error queue. Executing a read statement before sending a query causes the controller to wait indefinitely. The format specification for handling response messages depends on the programming language.

3 Getting Started
Reading Query Results into String Variables
The output of the instrument may be numeric or character data depending on what is queried. Refer to the specific command descriptions for the formats and types of data returned from queries.
NOTE
Express String Variables Using Exact Syntax
In Visual Basic, string variables are case sensitive and must be expressed exactly the same each time they are used.
The following example shows numeric data being returned to a string variable:
myScope.WriteString ":CHANnel1:RANGe?" Dim strQueryResult As String strQueryResult = myScope.ReadString MsgBox "Range (string):" + strQueryResult
After running this program, the controller displays: Range (string): +40.0E+00
Reading Query Results into Numeric Variables
The following example shows numeric data being returned to a numeric variable:
myScope.WriteString ":CHANnel1:RANGe?" Dim varQueryResult As Variant varQueryResult = myScope.ReadNumber MsgBox "Range (variant):" + CStr(varQueryResult)
After running this program, the controller displays: Range (variant): 40
Reading Definite-Length Block Query Response Data
Definite-length block query response data allows any type of device-dependent data to be transmitted over the system interface as a series of 8-bit binary data bytes. This is particularly useful for sending large quantities of data or 8-bit extended ASCII codes. The syntax is a pound sign (#) followed by a non-zero digit representing the number of digits in the decimal integer. After the non-zero digit is the decimal integer that states the number of 8-bit data bytes being sent. This is followed by the actual data. For example, for transmitting 1000 bytes of data, the syntax would be:
72

Getting Started 3
Number of Digits That Follow
Actual Data
#800001000<1000 bytes of data><terminator>
Number of Bytes to be Transmitted
Figure 2 Definite-length block response data
The "8" states the number of digits that follow, and "00001000" states the number of bytes to be transmitted. The VISA COM library's ReadIEEEBlock and WriteIEEEBlock methods understand the definite-length block syntax, so you can simply use variables that contain the data:
' Read oscilloscope setup using ":SYSTem:SETup?" query. myScope.WriteString ":SYSTem:SETup?" Dim varQueryResult As Variant varQueryResult = myScope.ReadIEEEBlock(BinaryType_UI1)
' Write learn string back to oscilloscope using ":SYSTem:SETup" command: myScope.WriteIEEEBlock ":SYSTem:SETup ", varQueryResult
Sending Multiple Queries and Reading Results
You can send multiple queries to the instrument within a single command string, but you must also read them back as a single query result. This can be accomplished by reading them back into a single string variable, multiple string variables, or multiple numeric variables. For example, to read the :TIMebase:RANGe?;DELay? query result into a single string variable, you could use the commands:
myScope.WriteString ":TIMebase:RANGe?;DELay?" Dim strQueryResult As String strQueryResult = myScope.ReadString MsgBox "Timebase range; delay:" + strQueryResult
When you read the result of multiple queries into a single string variable, each response is separated by a semicolon. For example, the output of the previous example would be:
Timebase range; delay: <range_value>;<delay_value>
To read the :TIMebase:RANGe?;DELay? query result into multiple string variables, you could use the ReadList method to read the query results into a string array variable using the commands:
myScope.WriteString ":TIMebase:RANGe?;DELay?" Dim strResults() As String strResults() = myScope.ReadList(ASCIIType_BSTR) MsgBox "Timebase range: " + strResults(0) + ", delay: " + strResults(1)

3 Getting Started
To read the :TIMebase:RANGe?;DELay? query result into multiple numeric variables, you could use the ReadList method to read the query results into a variant array variable using the commands:
myScope.WriteString ":TIMebase:RANGe?;DELay?" Dim varResults() As Variant varResults() = myScope.ReadList MsgBox "Timebase range: " + FormatNumber(varResults(0) * 1000, 4) + _
" ms, delay: " + FormatNumber(varResults(1) * 1000000, 4) + " us"
Checking Instrument Status
Status registers track the current status of the instrument. By checking the instrument status, you can find out whether an operation has been completed, whether the instrument is receiving triggers, and more. For more information, see Chapter 37, "Status Reporting," starting on page 1131 which explains how to check the status of the instrument.

Other Ways of Sending Commands
Standard Commands for Programmable Instrumentation (SCPI) can also be sent via a Telnet socket or through the Browser Web Control: · "Telnet Sockets" on page 75 · "Sending SCPI Commands Using Browser Web Control" on page 75
Telnet Sockets
The following information is provided for programmers who wish to control the oscilloscope with SCPI commands in a Telnet session. To connect to the oscilloscope via a telnet socket, issue the following command:
telnet <hostname> 5024
where <hostname> is the hostname of the oscilloscope. This will give you a command line with prompt. For a command line without a prompt, use port 5025. For example:
telnet <hostname> 5025
Sending SCPI Commands Using Browser Web Control
To send SCPI commands using the Browser Web Control feature, establish a connection to the oscilloscope via LAN as described in the InfiniiVision 3000 X-Series Oscilloscopes User's Guide. When you make the connection to the oscilloscope via LAN and the instrument's welcome page is displayed, select the Browser Web Control tab, then select the Remote Programming link.

Number Format
NR1 specifies integer data. NR3 specifies exponential data in floating point format (for example, -1.0E-3).
<NL> (Line Terminator)
<NL> = new line or linefeed (ASCII decimal 10). The line terminator, or a leading colon, will send the parser to the "root" of the command tree.
[ ] (Optional Syntax Terms)
Items enclosed in square brackets, [ ], are optional.
{ } (Braces)
When several items are enclosed by braces, { }, only one of these elements may be selected. Vertical line ( | ) indicates "or". For example, {ON | OFF} indicates that only ON or OFF may be selected, not both.
::= (Defined As)
::= means "defined as". For example, <A> ::= <B> indicates that <A> can be replaced by <B> in any statement containing <A>.

< > Angle brackets enclose words or characters that symbolize a program code parameter or an interface command.
... (Ellipsis)
... An ellipsis (trailing dots) indicates that the preceding element may be repeated one or more times.
n,..,p (Value Ranges)
n,..,p ::= all integers between n and p inclusive.
d (Digits)
d ::= A single ASCII numeric character 0 - 9.
Quoted ASCII String
A quoted ASCII string is a string delimited by either double quotes (") or single quotes ('). Some command parameters require a quoted ASCII string. For example, when using the Keysight VISA COM library in Visual Basic, the command:
myScope.WriteString ":CHANNEL1:LABEL 'One'"
has a quoted ASCII string of:
'One'
In order to read quoted ASCII strings from query return values, some programming languages require special handling or syntax.
Definite-Length Block Response Data
Definite-length block response data allows any type of device-dependent data to be transmitted over the system interface as a series of 8-bit binary data bytes. This is particularly useful for sending large quantities of data or 8-bit extended ASCII codes. This syntax is a pound sign (#) followed by a non-zero digit representing the number of digits in the decimal integer. After the non-zero digit is the decimal integer that states the number of 8-bit data bytes being sent. This is followed by the actual data. For example, for transmitting 1000 bytes of data, the syntax would be
#800001000<1000 bytes of data> <NL>
8 is the number of digits that follow 00001000 is the number of bytes to be transmitted

Introduction to Common (*) Commands
The common commands are defined by the IEEE 488.2 standard. They are implemented by all instruments that comply with the IEEE 488.2 standard. They provide some of the basic instrument functions, such as instrument identification and reset, reading the instrument setup, and determining how status is read and cleared.
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
169
5 Common (*) Commands
NOTE
Common commands can be received and processed by the instrument whether they are sent over the interface as separate program messages or within other program messages. If an instrument subsystem has been selected and a common command is received by the instrument, the instrument remains in the selected subsystem. For example, if the program message ":ACQuire:TYPE AVERage; *CLS; COUNt 256" is received by the instrument, the instrument sets the acquire type, then clears the status information and sets the average count. In contrast, if a root level command or some other subsystem command is within the program message, you must re-enter the original subsystem after the command. For example, the program message ":ACQuire:TYPE AVERage; :AUToscale; :ACQuire:COUNt 256" sets the acquire type, completes the autoscale, then sets the acquire count. In this example, :ACQuire must be sent again after the :AUToscale command in order to re-enter the ACQuire subsystem and set the count.
Each of the status registers has an enable (mask) register. By setting the bits in the enable register, you can select the status information you want to use.
170
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
Common (*) Commands 5
*CLS (Clear Status)
Command Syntax
(see page 1164)
*CLS
The *CLS common command clears the status data structures, the device-defined error queue, and the Request-for-OPC flag.
NOTE
If the *CLS command immediately follows a program message terminator, the output queue and the MAV (message available) bit are cleared.

The *LRN? query result contains the current state of the instrument. This query is similar to the :SYSTem:SETup? (see page 888) query, except that it contains ":SYST:SET " before the binary block data. The query result is a valid command that can be used to restore instrument settings at a later time.
<learn_string><NL>
<learn_string> ::= :SYST:SET <setup_data>
<setup_data> ::= binary block data in IEEE 488.2 # format
<learn string> specifies the current instrument setup. The block size is subject to change with different firmware revisions.
NOTE
The *LRN? query return format has changed from previous Keysight oscilloscopes to match the IEEE 488.2 specification which says that the query result must contain ":SYST:SET " before the binary block data.

Introduction to Root (:)
Commands
Root level commands control many of the basic operations of the instrument. These commands are always recognized by the parser if they are prefixed with a colon, regardless of current command tree position. After executing a root-level command, the parser is positioned at the root of the command tree.

Root (:) Commands 6
:ACTivity
Command Syntax Query Syntax
(see page 1164)
:ACTivity
The :ACTivity command clears the cumulative edge variables for the next activity query.
:ACTivity?
The :ACTivity? query returns whether there has been activity (edges) on the digital channels since the last query, and returns the current logic levels.
NOTE
Because the :ACTivity? query returns edge activity since the last :ACTivity? query, you must send this query twice before the edge activity result is valid.
Return Format
<edges>,<levels><NL> <edges> ::= presence of edges (16-bit integer in NR1 format). <levels> ::= logical highs or lows (16-bit integer in NR1 format). bit 0 ::= DIGital 0 bit 15 ::= DIGital 15
NOTE
A bit = 0 (zero) in the <edges> result indicates that no edges were detected on that channel (across the specified threshold voltage) since the last query. A bit = 1 (one) in the <edges> result indicates that edges have been detected on that channel (across the specified threshold voltage) since the last query. (The threshold voltage must be set appropriately for the logic levels of the signals being probed.)

Query Syntax
:AER?
The AER query reads the Arm Event Register. After the Arm Event Register is read, it is cleared. A "1" indicates the trigger system is in the armed state, ready to accept a trigger. The Armed Event Register is summarized in the Wait Trig bit of the Operation Status Event Register. A Service Request can be generated when the Wait Trig bit transitions and the appropriate enable bits have been set in the Operation Status Enable Register (OPEE) and the Service Request Enable Register (SRE).

The :AUToscale command evaluates all input signals and sets the correct conditions to display the signals. This is the same as pressing the [Auto Scale] key on the front panel. If one or more sources are specified, those specified sources will be enabled and all others blanked. The autoscale channels mode (see ":AUToscale:CHANnels" on page 202) is set to DISPlayed channels. Then, the autoscale is performed. When the :AUToscale command is sent, the following conditions are affected and actions are taken: · Thresholds. · Channels with activity around the trigger point are turned on, others are turned
off. · Channels are reordered on screen; analog channel 1 first, followed by the
remaining analog channels, then the digital channels 0-15. · Delay is set to 0 seconds. · Time/Div. The :AUToscale command does not affect the following conditions: · Label names. · Trigger conditioning. The :AUToscale command turns off the following items: · Cursors. · Measurements. · Math waveforms. · Reference waveforms. · Zoomed (delayed) time base mode. For further information on :AUToscale, see the User's Guide.

<source> ::= {CHANnel<n> | DIGital<d> | POD{1 | 2} | BUS{1 | 2} | FUNCtion | MATH | SBUS{1 | 2} | WMEMory<r>} for the MSO models
<n> ::= 1 to (# analog channels) in NR1 format
<d> ::= 0 to (# digital channels - 1) in NR1 format
<r> ::= 1 to (# ref waveforms) in NR1 format
The :BLANk command turns off (stops displaying) the specified channel, digital pod, math function, or serial decode bus. The :BLANk command with no parameter turns off all sources.
NOTE
To turn on (start displaying) a channel, etc., use the :VIEW command. The DISPlay commands, :CHANnel<n>:DISPlay, :FUNCtion:DISPlay, :POD<n>:DISPlay, :DIGital<n>:DISPlay, :SBUS<n>:DISPlay, or :WMEMory<r>:DISPlay, are the preferred method to turn on/off a channel, etc.
NOTE
MATH is an alias for FUNCtion.

<source> ::= {CHANnel<n> | DIGital<d> | POD{1 | 2} | BUS{1 | 2} | FUNCtion | MATH | SBUS{1 | 2}} for the MSO models
<n> ::= 1 to (# analog channels) in NR1 format
<d> ::= 0 to (# digital channels - 1) in NR1 format
The <source> parameter may be repeated up to 5 times.
The :DIGitize command is a specialized RUN command. It causes the instrument to acquire waveforms according to the settings of the :ACQuire commands subsystem. When the acquisition is complete, the instrument is stopped. If no argument is given, :DIGitize acquires the channels currently displayed. If no channels are displayed, all channels are acquired.
NOTE
The :DIGitize command is only executed when the :TIMebase:MODE is MAIN or WINDow.
NOTE
To halt a :DIGitize in progress, use the device clear command.
NOTE
MATH is an alias for FUNCtion.

:OVLenable (Overload Event Enable Register)
(see page 1164) Command Syntax :OVLenable <enable_mask>
<enable_mask> ::= 16-bit integer
The overload enable mask is an integer representing an input as described in the following table. The :OVLenable command sets the mask in the Overload Event Enable Register and enables the reporting of the Overload Event Register. If an overvoltage is sensed on a 50 input, the input will automatically switch to 1 M input impedance. If enabled, such an event will set bit 11 in the Operation Status Register.
NOTE
You can set analog channel input impedance to 50 on the 300 MHz, 500 MHz, and 1 GHz bandwidth oscilloscope models. On these same bandwidth models, if there are only two analog channels, you can also set external trigger input impedance to 50.

Introduction to :ACQuire
Commands
The ACQuire subsystem controls the way in which waveforms are acquired. These acquisition types are available: normal, averaging, peak detect, and high resolution.
Normal
233
7 :ACQuire Commands
The :ACQuire:TYPE NORMal command sets the oscilloscope in the normal acquisition mode. For the majority of user models and signals, NORMal mode yields the best oscilloscope picture of the waveform. Averaging The :ACQuire:TYPE AVERage command sets the oscilloscope in the averaging mode. You can set the count by sending the :ACQuire:COUNt command followed by the number of averages. In this mode, the value for averages is an integer from 2 to 65536. The COUNt value determines the number of averages that must be acquired. High-Resolution The :ACQuire:TYPE HRESolution command sets the oscilloscope in the high-resolution mode (also known as smoothing). This mode is used to reduce noise at slower sweep speeds where the digitizer samples faster than needed to fill memory for the displayed time range. Instead of decimating samples, they are averaged together to provide the value for one display point. The slower the sweep speed, the greater the number of samples that are averaged together for each display point. Peak Detect The :ACQuire:TYPE PEAK command sets the oscilloscope in the peak detect mode. In this mode, :ACQuire:COUNt has no meaning. Reporting the Setup Use :ACQuire? to query setup information for the ACQuire subsystem. Return Format The following is a sample response from the :ACQuire? query. In this case, the query was issued following a *RST command.

:ACQuire:COMPlete
(see page 1164)
Command Syntax :ACQuire:COMPlete <complete>
Query Syntax Return Format
<complete> ::= 100; an integer in NR1 format
The :ACQuire:COMPlete command affects the operation of the :DIGitize command. It specifies the minimum completion criteria for an acquisition. The parameter determines the percentage of the time buckets that must be "full" before an acquisition is considered complete. If :ACQuire:TYPE is NORMal, it needs only one sample per time bucket for that time bucket to be considered full. The only legal value for the :COMPlete command is 100. All time buckets must contain data for the acquisition to be considered complete.
:ACQuire:COMPlete?
The :ACQuire:COMPlete? query returns the completion criteria (100) for the currently selected mode.

In averaging mode, the :ACQuire:COUNt command specifies the number of values to be averaged for each time bucket before the acquisition is considered to be complete for that time bucket. When :ACQuire:TYPE is set to AVERage, the count can be set to any value from 2 to 65536.
NOTE
The :ACQuire:COUNt 1 command has been deprecated. The AVERage acquisition type with a count of 1 is functionally equivalent to the HRESolution acquisition type; however, you should select the high-resolution acquisition mode with the :ACQuire:TYPE HRESolution command instead.

:ACQuire:TYPE
(see page 1164) Command Syntax :ACQuire:TYPE <type>
<type> ::= {NORMal | AVERage | HRESolution | PEAK}
The :ACQuire:TYPE command selects the type of data acquisition that is to take place. The acquisition types are: · NORMal -- sets the oscilloscope in the normal mode. · AVERage -- sets the oscilloscope in the averaging mode. You can set the count
by sending the :ACQuire:COUNt command followed by the number of averages. In this mode, the value for averages is an integer from 1 to 65536. The COUNt value determines the number of averages that must be acquired. The AVERage type is not available when in segmented memory mode (:ACQuire:MODE SEGMented). · HRESolution -- sets the oscilloscope in the high-resolution mode (also known as smoothing). This mode is used to reduce noise at slower sweep speeds where the digitizer samples faster than needed to fill memory for the displayed time range. For example, if the digitizer samples at 200 MSa/s, but the effective sample rate is 1 MSa/s (because of a slower sweep speed), only 1 out of every 200 samples needs to be stored. Instead of storing one sample (and throwing others away), the 200 samples are averaged together to provide the value for one display point. The slower the sweep speed, the greater the number of samples that are averaged together for each display point. · PEAK -- sets the oscilloscope in the peak detect mode. In this mode, :ACQuire:COUNt has no meaning. The AVERage and HRESolution types can give you extra bits of vertical resolution. See the User's Guide for an explanation. When getting waveform data acquired using the AVERage and HRESolution types, be sure to use the WORD or ASCii waveform data formats to get the extra bits of vertical resolution.

The obsolete command ACQuire:TYPE:REALtime is functionally equivalent to sending ACQuire:MODE RTIME; TYPE NORMal.

Introduction to :CHANnel<n>
Commands
<n> ::= 1 to (# analog channels) in NR1 format
The CHANnel<n> subsystem commands control an analog channel (vertical or Y-axis of the oscilloscope). Channels are independently programmable for all offset, probe, coupling, bandwidth limit, inversion, vernier, and range (scale) functions. The channel number (1, 2, 3, or 4) specified in the command selects the analog channel that is affected by the command. A label command provides identifying annotations of up to 10 characters. You can toggle the channel displays on and off with the :CHANnel<n>:DISPlay command as well as with the root level commands :VIEW and :BLANk.
NOTE
The obsolete CHANnel subsystem is supported.
Reporting the Setup Use :CHANnel1?, :CHANnel2?, :CHANnel3? or :CHANnel4? to query setup information for the CHANnel<n> subsystem.
Return Format The following are sample responses from the :CHANnel<n>? query. In this case, the query was issued following a *RST command.

When the analog channel input impedance is set to 50, the input channels are protected against overvoltage. When an overvoltage condition is sensed, the input impedance for the channel is automatically changed to 1 M. The :CHANnel<n>:PROTection[:CLEar] command is used to clear (reset) the overload protection. It allows the channel to be used again in 50 mode after the signal that caused the overload has been removed from the channel input. Reset the analog channel input impedance to 50 (see ":CHANnel<n>:IMPedance" on page 274) after clearing the overvoltage protection.
:CHANnel<n>:PROTection?
The :CHANnel<n>:PROTection query returns the state of the input protection for CHANnel<n>. If a channel input has experienced an overload, TRIP (tripped) will be returned; otherwise NORM (normal) is returned.

Introduction to :FUNCtion Commands
The FUNCtion subsystem controls the math functions in the oscilloscope. As selected by the OPERation command, these math functions are available: · Operators:
· ADD · SUBTract · MULTiply
Operators perform their function on two analog channel sources. · Transforms:
· DIFF -- Differentiate · INTegrate -- The INTegrate:IOFFset command lets you specify a DC offset
correction factor. · FFT -- The SPAN, CENTer, VTYPe, and WINDow commands are used for FFT
functions. When FFT is selected, the horizontal cursors change from time to frequency (Hz), and the vertical cursors change from volts to decibel (dB). · SQRT -- Square root
Transforms operate on a single analog channel source or on a g(t) function that is the addition, subtraction, or multiplication of analog channel sources (specified by the GOFT commands).
With the DSOX3ADVMATH advanced math measurements license, these additional math functions are available: · Operators:
· DIVide · Transforms:
· LINear -- Ax + B -- The LINear commands set the gain (A) and offset (B) values for this function.
· SQUare · ABSolute -- Absolute Value

:FUNCtion[:FFT]:WINDow
(see page 1164)
Command Syntax :FUNCtion[:FFT]:WINDow <window>
<window> ::= {RECTangular | HANNing | FLATtop | BHARris}
The :FUNCtion[:FFT]:WINDow command allows the selection of four different windowing transforms or operations for the FFT (Fast Fourier Transform) function.
Query Syntax
The FFT operation assumes that the time record repeats. Unless an integral number of sampled waveform cycles exist in the record, a discontinuity is created between the end of one record and the beginning of the next. This discontinuity introduces additional frequency components about the peaks into the spectrum. This is referred to as leakage. To minimize leakage, windows that approach zero smoothly at the start and end of the record are employed as filters to the FFTs. Each window is useful for certain classes of input signals. · RECTangular -- useful for transient signals, and signals where there are an
integral number of cycles in the time record. · HANNing -- useful for frequency resolution and general purpose use. It is good
for resolving two frequencies that are close together, or for making frequency measurements. This is the default window. · FLATtop -- best for making accurate amplitude measurements of frequency peaks. · BHARris (Blackman-Harris) -- reduces time resolution compared to the rectangular window, but it improves the capacity to detect smaller impulses due to lower secondary lobes (provides minimal spectral leakage).
:FUNCtion[:FFT]:WINDow?
The :FUNCtion[:FFT]:WINDow? query returns the value of the window selected for the FFT function.
Return Format <window><NL>

Introduction to :MARKer
Commands
The MARKer subsystem commands set and query the settings of X-axis markers (X1 and X2 cursors) and the Y-axis markers (Y1 and Y2 cursors). You can set and query the marker mode and source, the position of the X and Y cursors, and query delta X and delta Y cursor values.
Reporting the Setup Use :MARKer? to query setup information for the MARKer subsystem.
Return Format The following is a sample response from the :MARKer? query. In this case, the query was issued following a *RST and ":MARKer:MODE MANual" command.
:MARK:X1Y1 CHAN1;X2Y2 CHAN1;MODE MAN

:MARKer:MODE
(see page 1164)
Command Syntax :MARKer:MODE <mode>
<mode> ::= {OFF | MEASurement | MANual | WAVeform}
The :MARKer:MODE command sets the cursors mode: · OFF -- removes the cursor information from the display. · MANual -- enables manual placement of the X and Y cursors.
Query Syntax Return Format
If the front-panel cursors are off, or are set to the front-panel Hex or Binary mode, setting :MARKer:MODE MANual will put the cursors in the front-panel Normal mode. · MEASurement -- cursors track the most recent measurement. Setting the mode to MEASurement sets the marker sources (:MARKer:X1Y1source and :MARKer:X2Y2source) to the measurement source (:MEASure:SOURce). Setting the measurement source remotely always sets the marker sources. · WAVeform -- the Y1 cursor tracks the voltage value at the X1 cursor of the waveform specified by the X1Y1source, and the Y2 cursor does the same for the X2 cursor and its X2Y2source.
:MARKer:MODE?
The :MARKer:MODE? query returns the current cursors mode.

:MARKer:YUNits:USE
When PERCent is selected for :MARKer:YUNits, the :MARKer:YUNits:USE command sets the current Y1 location as 0 percent and the current Y2 location as 100 percent. Once the 0 and 100 percent locations are set, inputs to and outputs from the :MARKer:Y1Position, :MARKer:Y2Position, and :MARKer:YDELta commands/queries are relative to the set locations. · "Introduction to :MARKer Commands" on page 390 · ":MARKer:YUNits" on page 404 · ":MARKer:X1Y1source" on page 393 · ":MARKer:X2Y2source" on page 395 · ":MEASure:SOURce" on page 460 · ":MARKer:Y1Position" on page 399 · ":MARKer:Y2Position" on page 401 · ":MARKer:YDELta" on page 403

Measurement Error If a measurement cannot be made (typically because the proper portion of the waveform is not displayed), the value +9.9E+37 is returned for that measurement. Making Measurements If more than one waveform, edge, or pulse is displayed, time measurements are made on the portion of the displayed waveform closest to the trigger reference (left, center, or right). When making measurements in the zoomed (delayed) time base mode (:TIMebase:MODE WINDow), the oscilloscope will attempt to make the measurement inside the zoomed sweep window. If the measurement is an average and there are not three edges, the oscilloscope will revert to the mode of making the measurement at the start of the main sweep. When the command form is used, the measurement result is displayed on the instrument. When the query form of these measurements is used, the measurement is made one time, and the measurement result is returned over the bus. Measurements are made on the displayed waveforms specified by the :MEASure:SOURce command. The MATH source is an alias for the FUNCtion source. Not all measurements are available on the digital channels or FFT (Fast Fourier Transform). Reporting the Setup Use the :MEASure? query to obtain setup information for the MEASure subsystem. (Currently, this is only :MEASure:SOURce.) Return Format The following is a sample response from the :MEASure? query. In this case, the query was issued following a *RST command.

The :MEASure:DELay command places the instrument in the continuous measurement mode and starts a delay measurement. The measurement is taken as:
delay = t(<edge spec 2>) - t(<edge spec 1>) where the <edge spec> definitions are set by the :MEASure:DEFine command
NOTE
The :MEASure:DELay command and the front-panel delay measurement differ from the :MEASure:DELay? query.
The delay command or front-panel measurement run the delay measurement in auto-edge select mode. In this mode, you can select the edge polarity, but the instrument will select the edges that will make the best possible delay measurement. The source1 edge chosen will be the edge that meets the polarity specified and is closest to the timebase reference point. The source2 edge selected will be that edge of the specified polarity that gives the first of the following criteria: · The smallest positive delay value that is less than source1 period. · The smallest negative delay that is less than source1 period. · The smallest absolute value of delay. The :MEASure:DELay? query will make the measurement using the edges specified by the :MEASure:DEFine command.
Query Syntax
:MEASure:DELay? [<source1>][,<source2>]
The :MEASure:DELay? query measures and returns the delay between source1 and source2. The delay measurement is made from the user-defined slope and edge count of the signal connected to source1, to the defined slope and edge count of the signal connected to source2. Delay measurement slope and edge parameters are selected using the :MEASure:DEFine command. Also in the :MEASure:DEFine command, you can set upper, middle, and lower threshold values. It is the middle threshold value that is used when performing the delay query. The standard upper, middle, and lower measurement thresholds are

Query Syntax
:MEASure:OVERshoot? [<source>]
The :MEASure:OVERshoot? query measures and returns the overshoot of the edge closest to the trigger reference, displayed on the screen. The method used to determine overshoot is to make three different vertical value measurements: Vtop, Vbase, and either Vmax or Vmin, depending on whether the edge is rising or falling. For a rising edge:
overshoot = ((Vmax-Vtop) / (Vtop-Vbase)) x 100 For a falling edge:
Return Format
overshoot = ((Vbase-Vmin) / (Vtop-Vbase)) x 100 Vtop and Vbase are taken from the normal histogram of all waveform vertical values. The extremum of Vmax or Vmin is taken from the waveform interval right after the chosen edge, halfway to the next edge. This more restricted definition is used instead of the normal one, because it is conceivable that a signal may have more preshoot than overshoot, and the normal extremum would then be dominated by the preshoot of the following edge.

:MEASure:STATistics:INCRement
This command updates the statistics once (incrementing the count by one) using the current measurement values. It corresponds to the front panel Increment Statistics softkey in the Measurement Statistics Menu. This command lets you, for example, gather statistics over multiple pulses captured in a single acquisition. To do this, change the horizontal position and enter the command for each new pulse that is measured. This command is only allowed when the oscilloscope is stopped and quick measurements are on. The command is allowed in segmented acquisition mode even though the corresponding front panel softkey is not available. · "Introduction to :MEASure Commands" on page 420 · ":MEASure:STATistics" on page 462 · ":MEASure:STATistics:DISPlay" on page 463 · ":MEASure:STATistics:RESet" on page 466 · ":MEASure:RESults" on page 454

:MEASure:TEDGe
(see page 1164) Query Syntax :MEASure:TEDGe? <slope><occurrence>[,<source>]
<slope> ::= direction of the waveform. A rising slope is indicated by a space or plus sign (+). A falling edge is indicated by a minus sign (-).
<occurrence> ::= the transition to be reported. If the occurrence number is one, the first crossing from the left screen edge is reported. If the number is two, the second crossing is reported, etc.
<source> ::= {<digital channels> | CHANnel<n> | FUNCtion | MATH | WMEMory<r>}
<digital channels> ::= DIGital<d> for the MSO models <n> ::= 1 to (# of analog channels) in NR1 format <r> ::= 1-2 in NR1 format <d> ::= 0 to (# digital channels - 1) in NR1 format
When the :MEASure:TEDGe query is sent, the displayed signal is searched for the specified transition. The time interval between the trigger event and this occurrence is returned as the response to the query. The sign of the slope selects a rising (+) or falling (-) edge. If no sign is specified for the slope, it is assumed to be the rising edge. The magnitude of occurrence defines the occurrence to be reported. For example, +3 returns the time for the third time the waveform crosses the midpoint threshold in the positive direction. Once this crossing is found, the oscilloscope reports the time at that crossing in seconds, with the trigger point (time zero) as the reference. If the specified crossing cannot be found, the oscilloscope reports +9.9E+37. This value is returned if the waveform does not cross the specified vertical value, or if the waveform does not cross the specified vertical value for the specific number of times in the direction specified. You can make delay and phase measurements using the MEASure:TEDGe command:
Delay = time at the nth rising or falling edge of the channel - time at the same edge of another channel Phase = (delay between channels / period of channel) x 360 For an example of making a delay and phase measurement, see ":MEASure:TEDGe Code" on page 469. If the optional source parameter is specified, the current source is modified.

:MEASure:TVALue
(see page 1164) Query Syntax :MEASure:TVALue? <value>, [<slope>]<occurrence>[,<source>]
<value> ::= the vertical value that the waveform must cross. The value can be volts or a math function value such as dB, Vs, or V/s.
<slope> ::= direction of the waveform. A rising slope is indicated by a plus sign (+). A falling edge is indicated by a minus sign (-).
<occurrence> ::= the transition to be reported. If the occurrence number is one, the first crossing is reported. If the number is two, the second crossing is reported, etc.
<source> ::= {CHANnel<n> | FUNCtion | MATH | WMEMory<r>}
<n> ::= 1 to (# analog channels) in NR1 format
<r> ::= 1-2 in NR1 format
When the :MEASure:TVALue? query is sent, the displayed signal is searched for the specified value level and transition. The time interval between the trigger event and this defined occurrence is returned as the response to the query. The specified value can be negative or positive. To specify a negative value, use a minus sign (-). The sign of the slope selects a rising (+) or falling (-) edge. If no sign is specified for the slope, it is assumed to be the rising edge. The magnitude of the occurrence defines the occurrence to be reported. For example, +3 returns the time for the third time the waveform crosses the specified value level in the positive direction. Once this value crossing is found, the oscilloscope reports the time at that crossing in seconds, with the trigger point (time zero) as the reference. If the specified crossing cannot be found, the oscilloscope reports +9.9E+37. This value is returned if the waveform does not cross the specified value, or if the waveform does not cross the specified value for the specified number of times in the direction specified. If the optional source parameter is specified, the current source is modified.

Introduction to :MTESt Commands
Mask testing automatically compares the current displayed waveform with the boundaries of a set of polygons that you define. Any waveform or sample that falls within the boundaries of one or more polygons is recorded as a failure.
Reporting the Setup Use :MTESt? to query setup information for the MTESt subsystem.
Return Format The following is a sample response from the :MTESt? query. In this case, the query was issued following a *RST command.

:MTESt:AMASk:CREate
The :MTESt:AMASk:CREate command automatically constructs a mask around the current selected channel, using the tolerance parameters defined by the :MTESt:AMASk:XDELta, :MTESt:AMASk:YDELta, and :MTESt:AMASk:UNITs commands. The mask only encompasses the portion of the waveform visible on the display, so you must ensure that the waveform is acquired and displayed consistently to obtain repeatable results. The :MTESt:SOURce command selects the channel and should be set before using this command. · "Introduction to :MTESt Commands" on page 507 · ":MTESt:AMASk:XDELta" on page 514 · ":MTESt:AMASk:YDELta" on page 515 · ":MTESt:AMASk:UNITs" on page 513 · ":MTESt:AMASk:SOURce" on page 512 · ":MTESt:SOURce" on page 537 · "Example Code" on page 507

:MTESt:AMASk:SOURce
(see page 1164)
Command Syntax :MTESt:AMASk:SOURce <source>
<source> ::= CHANnel<n>
<n> ::= 1 to (# analog channels) in NR1 format
The :MTESt:AMASk:SOURce command selects the source for the interpretation of the :MTESt:AMASk:XDELta and :MTESt:AMASk:YDELta parameters when :MTESt:AMASk:UNITs is set to CURRent.
When UNITs are CURRent, the XDELta and YDELta parameters are defined in terms of the channel units, as set by the :CHANnel<n>:UNITs command, of the selected source. Suppose that UNITs are CURRent and that you set SOURce to CHANNEL1, which is using units of volts. Then you can define AMASk:XDELta in terms of volts and AMASk:YDELta in terms of seconds.
Query Syntax Return Format
This command is the same as the :MTESt:SOURce command.
:MTESt:AMASk:SOURce?

:MTESt:AMASk:UNITs
(see page 1164)
Command Syntax :MTESt:AMASk:UNITs <units>
Query Syntax
<units> ::= {CURRent | DIVisions}
The :MTESt:AMASk:UNITs command alters the way the mask test subsystem interprets the tolerance parameters for automasking as defined by :MTESt:AMASk:XDELta and :MTESt:AMASk:YDELta commands. · CURRent -- the mask test subsystem uses the units as set by the
:CHANnel<n>:UNITs command, usually time for X and voltage for Y. · DIVisions -- the mask test subsystem uses the graticule as the measurement
system, so tolerance settings are specified as parts of a screen division. The mask test subsystem maintains separate XDELta and YDELta settings for CURRent and DIVisions. Thus, XDELta and YDELta are not converted to new values when the UNITs setting is changed.
:MTESt:AMASk:UNITs?
The :MTESt:AMASk:UNITs query returns the current measurement units setting for the mask test automask feature.

:MTESt:AMASk:XDELta
(see page 1164)
Command Syntax :MTESt:AMASk:XDELta <value>
Query Syntax Return Format
<value> ::= X delta value in NR3 format
The :MTESt:AMASk:XDELta command sets the tolerance in the X direction around the waveform for the automasking feature. The absolute value of the tolerance will be added and subtracted to horizontal values of the waveform to determine the boundaries of the mask. The horizontal tolerance value is interpreted based on the setting specified by the :MTESt:AMASk:UNITs command; thus, if you specify 250-E3, the setting for :MTESt:AMASk:UNITs is CURRent, and the current setting specifies time in the horizontal direction, the tolerance will be ±250 ms. If the setting for :MTESt:AMASk:UNITs is DIVisions, the same X delta value will set the tolerance to ±250 millidivisions, or 1/4 of a division.
:MTESt:AMASk:XDELta?
The :MTEST:AMASk:XDELta? query returns the current setting of the X tolerance for automasking. If your computer program will interpret this value, it should also request the current measurement system using the :MTESt:AMASk:UNITs query.

(see page 1164)
Command Syntax :MTESt:AMASk:YDELta <value>
Query Syntax Return Format
<value> ::= Y delta value in NR3 format
The :MTESt:AMASk:YDELta command sets the vertical tolerance around the waveform for the automasking feature. The absolute value of the tolerance will be added and subtracted to vertical values of the waveform to determine the boundaries of the mask. The vertical tolerance value is interpreted based on the setting specified by the :MTESt:AMASk:UNITs command; thus, if you specify 250-E3, the setting for :MTESt:AMASk:UNITs is CURRent, and the current setting specifies voltage in the vertical direction, the tolerance will be ±250 mV. If the setting for :MTESt:AMASk:UNITs is DIVisions, the same Y delta value will set the tolerance to ±250 millidivisions, or 1/4 of a division.
:MTESt:AMASk:YDELta?
The :MTESt:AMASk:YDELta? query returns the current setting of the Y tolerance for automasking. If your computer program will interpret this value, it should also request the current measurement system using the :MTESt:AMASk:UNITs query.

:MTESt:SCALe:X1
(see page 1164)
Command Syntax :MTESt:SCALe:X1 <x1_value>
<x1_value> ::= X1 value in NR3 format
The :MTESt:SCALe:X1 command defines where X=0 in the base coordinate system used for mask testing. The other X-coordinate is defined by the :MTESt:SCALe:XDELta command. Once the X1 and XDELta coordinates are set, all X values of vertices in the mask regions are defined with respect to this value, according to the equation:
Query Syntax Return Format
X = (X * X) + X1
Thus, if you set X1 to 100 ms, and XDELta to 100 ms, an X value of 0.100 is a vertex at 110 ms. The oscilloscope uses this equation to normalize vertices. This simplifies reprogramming to handle different data rates. For example, if you halve the period of the waveform of interest, you need only to adjust the XDELta value to set up the mask for the new waveform. The X1 value is a time value specifying the location of the X1 coordinate, which will then be treated as X=0 for mask regions coordinates.
:MTESt:SCALe:X1?
The :MTESt:SCALe:X1? query returns the current X1 coordinate setting.

:MTESt:SCALe:XDELta
(see page 1164)
Command Syntax :MTESt:SCALe:XDELta <xdelta_value>
<xdelta_value> ::= X delta value in NR3 format
The :MTESt:SCALe:XDELta command defines the position of the X2 marker with respect to the X1 marker. In the mask test coordinate system, the X1 marker defines where X=0; thus, the X2 marker defines where X=1. Because all X vertices of the regions defined for mask testing are normalized with respect to X1 and X, redefining X also moves those vertices to stay in the same locations with respect to X1 and X. Thus, in many applications, it is best if you define XDELta as a pulse width or bit period. Then, a change in data rate without corresponding changes in the waveform can easily be handled by changing X. The X-coordinate of polygon vertices is normalized using this equation:
Query Syntax Return Format
X = (X * X) + X1
The X delta value is a time value specifying the distance of the X2 marker with respect to the X1 marker. For example, if the period of the waveform you wish to test is 1 ms, setting X to 1 ms ensures that the waveform's period is between the X1 and X2 markers.
:MTESt:SCALe:XDELta?
The :MTESt:SCALe:XDELta? query returns the current value of X.

Command Syntax
(see page 1164)
:MTESt:SCALe:Y1 <y1_value>
<y1_value> ::= Y1 value in NR3 format
The :MTESt:SCALe:Y1 command defines where Y=0 in the coordinate system for mask testing. All Y values of vertices in the coordinate system are defined with respect to the boundaries set by SCALe:Y1 and SCALe:Y2 according to the equation:
Query Syntax Return Format
Y = (Y * (Y2 - Y1)) + Y1
Thus, if you set Y1 to 100 mV, and Y2 to 1 V, a Y value of 0.100 in a vertex is at 190 mV. The Y1 value is a voltage value specifying the point at which Y=0.
:MTESt:SCALe:Y1?

:POWer Commands 24
:POWer:DESKew
Command Syntax
(see page 1164)
:POWer:DESKew
The :POWer:DESKew command launches the auto deskew process on the oscilloscope. Before sending this command: 1 Demagnetize and zero-adjust the current probe.
Refer to the current probe's documentation for instructions on how to do this. 2 Make connections to the U1880A deskew fixture as described in the
oscilloscope's connection dialog or in the DSOX3PWR Power Measurement Application User's Guide. 3 Make sure the voltage probe and current probe channels are specified appropriately using the :POWer:SIGNals:SOURce:VOLTage1 and :POWer:SIGNals:SOURce:CURRent1 commands.
NOTE
Use the lowest attenuation setting on the high voltage differential probes whenever possible because the voltage levels on the deskew fixture are very small. Using a higher attenuation setting may yield inaccurate skew values (and affect the measurements made) because the noise level is magnified as well.
See Also
The deskew values are saved in the oscilloscope until a factory default or secure erase is performed. The next time you run the Power Application, you can use the saved deskew values or perform the deskew again. Generally, you need to perform the deskew again when part of the test setup changes (for example, a different probe, different oscilloscope channel, etc.) or when the ambient temperature has changed. · ":POWer:SIGNals:SOURce:VOLTage<i>" on page 599 · ":POWer:SIGNals:SOURce:CURRent<i>" on page 598

:POWer:EFFiciency:APPLy
The :POWer:EFFiciency:APPLy command applies the effieciency power analysis. Efficiency analysis tests the overall efficiency of the power supply by measuring the output power over the input power.
NOTE
Efficiency analysis requires a 4-channel oscilloscope because input voltage, input current, output voltage, and output current are measured.

:POWer:HARMonics:APPLy
The :POWer:HARMonics:APPLy command applies the current harmonics analysis. Switching power supplies draw a range of harmonics from the AC mains. Standard limits are set for these harmonics because these harmonics can travel back to the supply grid and cause problems with other devices on the grid. Use the Current Harmonics analysis to test a switching power supply's current harmonics to pre-compliance standard of IEC61000-3-2 (Class A, B, C, or D). The analysis presents up to 40 harmonics. · ":POWer:HARMonics:DATA" on page 555 · ":POWer:HARMonics:DISPlay" on page 556 · ":POWer:HARMonics:FAILcount" on page 557 · ":POWer:HARMonics:LINE" on page 558 · ":POWer:HARMonics:POWerfactor" on page 559 · ":POWer:HARMonics:STANdard" on page 561 · ":POWer:HARMonics:STATus" on page 562 · ":POWer:HARMonics:RUNCount" on page 560 · ":POWer:HARMonics:THD" on page 563

:POWer:PSRR:APPLy
The :POWer:PSRR:APPLy command applies the power supply rejection ratio (PSRR) analysis. The Power Supply Rejection Ratio (PSRR) test is used to determine how well a voltage regulator rejects ripple noise over different frequency range. This analysis provides a signal from the oscilloscope's waveform generator that sweeps its frequency. This signal is used to inject ripple to the DC voltage that feeds the voltage regulator. The AC RMS ratio of the input over the output is measured and is plotted over the range of frequencies. · ":POWer:PSRR:FREQuency:MAXimum" on page 575 · ":POWer:PSRR:FREQuency:MINimum" on page 576 · ":POWer:PSRR:RMAXimum" on page 577

:POWer:QUALity:APPLy
The :POWer:QUALity:APPLy command applies the selected power quality analysis type (:POWer:QUALity:TYPE). The power quality analysis shows the quality of the AC input line. Some AC current may flow back into and back out of the load without delivering energy. This current, called reactive or harmonic current, gives rise to an "apparent" power which is larger than the actual power consumed. Power quality is gauged by these measurements: power factor, apparent power, true power, reactive power, crest factor, and phase angle of the current and voltage of the AC line. · ":POWer:QUALity:TYPE" on page 579 · ":MEASure:FACTor" on page 494 · ":MEASure:REAL" on page 502 · ":MEASure:APParent" on page 489 · ":MEASure:REACtive" on page 501 · ":MEASure:CRESt" on page 491 · ":MEASure:ANGLe" on page 488

<quality> ::= {FACTor | REAL | APParent | REACtive | CRESt | ANGLe}
The :POWer:QUALity:TYPE command selects the type of measurement to make in the power quality analysis: · FACTor -- Power Factor -- Ratio of the actual power to the apparent power. · REAL -- Real (Actual) Power -- The portion of power flow that, averaged over a
complete cycle of the AC waveform, results in net transfer of energy in one direction. · APParent -- Apparent Power -- The portion of power flow due to stored energy, which returns to the source in each cycle. · REACtive -- Reactive Power -- The difference between apparent power and real power due to reactance. · CRESt -- Crest Factor -- Crest factor is the ratio between the instantaneous peak current/voltage required by the load and the RMS current/voltage (RMS stands for Root Mean Square, which is a type of average). · ANGLe -- Phase Angle -- In the power triangle (the right triangle where apparent_power2 = real_power2 + reactive_power2), phase angle is the angle between the apparent power and the real power, indicating the amount of reactive power.
:POWer:QUALity:TYPE?
The :POWer:QUALity:TYPE query returns the selected power quality measurement type.

Introduction to The :RECall subsystem provides commands to recall previously saved oscilloscope :RECall Commands setups, reference waveforms, and masks.
Reporting the Setup Use :RECall? to query setup information for the RECall subsystem.
Return Format The following is a sample response from the :RECall? query. In this case, the query was issued following the *RST command.

Recalling Files From a USB Storage Device When :RECall commands have a "quoted ASCII string" <file_name> parameter, you can recall files from a connected USB storage device. For example:
' To recall a setup file from a connected USB storage device: myScope.WriteString ":RECall:SETup:STARt ""\usb\my_setup_file.scp"""

For internal locations, the <column> parameter is ignored. For external (USB storage device) files, the column parameter is optional. If no <column> parameter is entered, and it is a 2-column file, the 2nd column (assumed to be voltage) is automatically be selected. If the <column> parameter is entered, and that column does not exist in the file, the operation fails. When recalling arbitrary waveforms (from an external USB storage device) that were not saved from the oscilloscope, be aware that the oscilloscope uses a maximum of 8192 points for an arbitrary waveform. For more efficient recalls, make sure your arbitrary waveforms are 8192 points or less. · "Introduction to :RECall Commands" on page 614 · ":RECall:FILename" on page 616 · ":SAVE:ARBitrary[:STARt]" on page 624

Introduction to :SAVE Commands
The :SAVE subsystem provides commands to save oscilloscope setups, screen images, and data. :SAV is an acceptable short form for :SAVE.
Reporting the Setup Use :SAVE? to query setup information for the SAVE subsystem.
Return Format The following is a sample response from the :SAVE? query. In this case, the query was issued following the *RST command.
:SAVE:FIL "";:SAVE:IMAG:AREA GRAT;FACT 0;FORM TIFF;INKS 0;PAL MON;:SAVE:PWD "C:/setups/";:SAVE:WAV:FORM NONE;LENG 1000;SEGM CURR
Saving Files to a USB Storage Device When :SAVE commands have a "quoted ASCII string" <file_name> parameter, you can save files to a connected USB storage device. For example:
' To save a setup file to a connected USB storage device: myScope.WriteString ":SAVE:SETup:STARt ""\usb\my_setup_file.scp"""

The :SBUS subsystem commands control the serial decode bus viewing, mode, and other options.
These commands are only valid on oscilloscope models when a serial decode option has been licensed.
The following serial bus decode/trigger types are available (see ":TRIGger:MODE" on page 912). · CAN (Controller Area Network) triggering-- will trigger on CAN version 2.0A and
2.0B signals. Setup consists of connecting the oscilloscope to a CAN signal. Baud rate, signal source, and signal polarity, and type of data to trigger on can be specified. You can trigger on CAN data and identifier patterns and you can set the bit sample point. · I2S (Inter-IC Sound or Integrated Interchip Sound bus) triggering-- consists of connecting the oscilloscope to the serial clock, word select, and serial data lines, then triggering on a data value.
645
27 :SBUS<n> Commands
NOTE
· IIC (Inter-IC bus) triggering-- consists of connecting the oscilloscope to the serial data (SDA) line and the serial clock (SCL) line, then triggering on a stop/start condition, a restart, a missing acknowledge, or on a read/write frame with a specific device address and data value.
· LIN (Local Interconnect Network) triggering-- will trigger on LIN sync break at the beginning of a message frame.You can trigger on Sync Break, Frame IDs, or Frame IDs and Data.
· SPI (Serial Peripheral Interface) triggering-- consists of connecting the oscilloscope to a clock, data (MOSI or MISO), and framing signal. You can then trigger on a data pattern during a specific framing period. The serial data string can be specified to be from 4 to 64 bits long.
· UART/RS-232 triggering (with Option 232) -- lets you trigger on RS-232 serial data.
Two I2S buses or two SPI buses cannot be decoded on both SBUS1 and SBUS2 at the same time.
Reporting the Setup Use :SBUS<n>? to query setup information for the :SBUS<n> subsystem.
Return Format The following is a sample response from the :SBUS1? query. In this case, the query was issued following a *RST command.

:SBUS<n>:I2S:TRIGger
(see page 1164) Command Syntax :SBUS<n>:I2S:TRIGger <operator>
<operator> ::= {EQUal | NOTequal | LESSthan | GREaterthan | INRange | OUTRange | INCReasing | DECReasing}
The :SBUS<n>:I2S:TRIGger command sets the I2S trigger operator: · EQUal-- triggers on the specified audio channel's data word when it equals the
specified word. · NOTequal -- triggers on any word other than the specified word. · LESSthan -- triggers when the channel's data word is less than the specified
value. · GREaterthan -- triggers when the channel's data word is greater than the
specified value. · INRange -- enter upper and lower values to specify the range in which to
trigger. · OUTRange -- enter upper and lower values to specify range in which trigger will
not occur. · INCReasing -- triggers when the data value makes a certain increase over time
and the specified value is met or exceeded. Use the :SBUS<n>:I2S:TRIGger:RANGe command to set "Trigger" and "Armed" values. The "Trigger" value is the value that must be met or exceeded to cause the trigger. The "Armed" value is the value the data must go below in order to re-arm the oscilloscope (ready it to trigger again).

:SBUS<n>:I2S:TRIGger:PATTern:DATA
(see page 1164) Command Syntax :SBUS<n>:I2S:TRIGger:PATTern:DATA <string>
<string> ::= "n" where n ::= 32-bit integer in signed decimal when <base> = DECimal
<string> ::= "nn...n" where n ::= {0 | 1 | X | $} when <base> = BINary
<string> ::= "0xnn...n" where n ::= {0,..,9 | A,..,F | X | $} when <base> = HEX
NOTE
<base> is specified with the :SBUS<n>:I2S:TRIGger:PATTern:FORMat command. The default <base> is DECimal.
NOTE NOTE
The :SBUS<n>:I2S:TRIGger:PATTern:DATA command specifies the I2S trigger data pattern searched for in each I2S message. Set a <string> bit to "0" or "1" to set the corresponding bit in the data pattern to low or high, respectively. Set a <string> bit to "X" to ignore (mask off) that bit in the data pattern. Use the "$" character to indicate that the value of the corresponding bit will not be changed (the existing bit value is used). When <base> = DECimal, the "X" and "$" characters cannot be entered. When queried, the "$" character is returned when any bits in the pattern have the value of "X" and <base> = DECimal. When any bits in a given nibble have the value of "X" and <base> = HEX, the "$" character is returned for the corresponding nibble.
The :SBUS<n>:I2S:TRIGger:PATTern:DATA command specifies the I2S trigger data pattern used by the EQUal, NOTequal, GREaterthan, and LESSthan trigger conditions. If the GREaterthan or LESSthan trigger condition is selected, the bits specified to be masked off ("X") will be interpreted as 0's.
The length of the trigger data value is determined by the :SBUS<n>:I2S:RWIDth and :SBUS<n>:I2S:TWIDth commands. When the receiver word size is less than the transmitter word size, the data length is equal to the receiver word size. When the receiver word size is greater than the transmitter word size, the data length is equal to the transmitter word size.
NOTE
If more bits are sent for <string> than the specified trigger data length, the most significant bits will be truncated. If the word size is changed after the <string> is programmed, the added or deleted bits will be added to or deleted from the least significant bits.

<string> ::= "0xnn...n" where n ::= {0,..,9 | A,..,F} for hexadecimal
The :SBUS<n>:I2S:TRIGger:RANGe command sets the lower and upper range boundaries used by the INRange, OUTRange, INCReasing, and DECReasing trigger conditions. You can enter the parameters in any order -- the smaller value becomes the <lower> and the larger value becomes the <upper>. Note that for INCReasing and DECReasing, the <lower> and <upper> values correspond to the "Armed" and "Trigger" softkeys.
NOTE
The length of the <lower> and <upper> values is determined by the :SBUS<n>:I2S:RWIDth and :SBUS<n>:I2S:TWIDth commands. When the receiver word size is less than the transmitter word size, the length is equal to the receiver word size. When the receiver word size is greater than the transmitter word size, the length is equal to the transmitter word size.

<string> ::= "0xnn...n" where n ::= {0,..,9 | A,..,F | X | $} when <base> = HEX
NOTE
<base> is specified with the :SBUS<n>:LIN:TRIGger:PATTern:FORMat command. The default <base> is BINary.
NOTE
The :SBUS<n>:LIN:TRIGger:PATTern:DATA command specifies the LIN trigger data pattern searched for in each LIN data field. Set a <string> bit to "0" or "1" to set the corresponding bit in the data pattern to low or high, respectively. Set a <string> bit to "X" to ignore (mask off) that bit in the data pattern. Use the "$" character to indicate that the value of the corresponding bit will not be changed (the existing bit value is used). When <base> = DECimal, the "X" and "$" characters cannot be entered. When queried, the "$" character is returned when any bits in the pattern have the value of "X" and <base> = DECimal. When any bits in a given nibble have the value of "X" and <base> = HEX, the "$" character is returned for the corresponding nibble.
The length of the trigger data value is determined by the :SBUS<n>:LIN:TRIGger:PATTern:DATA:LENGth command.
NOTE
If more bits are sent for <string> than the specified trigger pattern data length, the most significant bits will be truncated. If the data length size is changed after the <string> is programmed, the added or deleted bits will be added to or deleted from the least significant bits.
Query Syntax Return Format
:SBUS<n>:LIN:TRIGger:PATTern:DATA?

Introduction to :TIMebase Commands
The TIMebase subsystem commands control the horizontal (X-axis) functions and set the oscilloscope to X-Y mode (where channel 1 becomes the X input and channel 2 becomes the Y input). The time per division, delay, vernier control, and reference can be controlled for the main and window (zoomed) time bases.
Reporting the Setup Use :TIMebase? to query setup information for the TIMebase subsystem.
Return Format The following is a sample response from the :TIMebase? query. In this case, the query was issued following a *RST command.

Introduction to :TRIGger
Commands
Control the trigger modes and parameters for each trigger type. See: · "Introduction to :TRIGger Commands" on page 903 · "General :TRIGger Commands" on page 905 · ":TRIGger:DELay Commands" on page 915 · ":TRIGger:EBURst Commands" on page 922 · ":TRIGger[:EDGE] Commands" on page 927 · ":TRIGger:GLITch Commands" on page 933 (Pulse Width trigger) · ":TRIGger:OR Commands" on page 942 · ":TRIGger:PATTern Commands" on page 944 · ":TRIGger:RUNT Commands" on page 952 · ":TRIGger:SHOLd Commands" on page 957 · ":TRIGger:TRANsition Commands" on page 963 · ":TRIGger:TV Commands" on page 968 · ":TRIGger:USB Commands" on page 978
The commands in the TRIGger subsystem define the conditions for an internal trigger. Many of these commands are valid in multiple trigger modes.
The default trigger mode is :EDGE.
The trigger subsystem controls the trigger sweep mode and the trigger specification. The trigger sweep (see ":TRIGger:SWEep" on page 914) can be AUTO or NORMal. · NORMal mode -- displays a waveform only if a trigger signal is present and the
trigger conditions are met. Otherwise the oscilloscope does not trigger and the display is not updated. This mode is useful for low-repetitive-rate signals. · AUTO trigger mode -- generates an artificial trigger event if the trigger specification is not satisfied within a preset time, acquires unsynchronized data and displays it.
AUTO mode is useful for signals other than low-repetitive-rate signals. You must use this mode to display a DC signal because there are no edges on which to trigger.
903
31 :TRIGger Commands
The following trigger types are available (see ":TRIGger:MODE" on page 912). · Edge triggering-- identifies a trigger by looking for a specified slope and voltage
level on a waveform. · Nth Edge Burst triggering-- lets you trigger on the Nth edge of a burst that occurs
after an idle time. · Pulse width triggering-- (:TRIGger:GLITch commands) sets the oscilloscope to
trigger on a positive pulse or on a negative pulse of a specified width. · Pattern triggering-- identifies a trigger condition by looking for a specified
pattern. This pattern is a logical AND combination of the channels. You can also trigger on a specified time duration of a pattern. · TV triggering-- is used to capture the complicated waveforms of television equipment. The trigger circuitry detects the vertical and horizontal interval of the waveform and produces triggers based on the TV trigger settings you selected. TV triggering requires greater than ¼ division of sync amplitude with any analog channel as the trigger source. · USB (Universal Serial Bus) triggering-- will trigger on a Start of Packet (SOP), End of Packet (EOP), Reset Complete, Enter Suspend, or Exit Suspend signal on the differential USB data lines. USB Low Speed and Full Speed are supported by this trigger.
Reporting the Setup Use :TRIGger? to query setup information for the TRIGger subsystem.
Return Format The return format for the TRIGger? query varies depending on the current mode. The following is a sample response from the :TRIGger? query. In this case, the query was issued following a *RST command.

(see page 1164)
Command Syntax :TRIGger:HOLDoff <holdoff_time>
Query Syntax Return Format
<holdoff_time> ::= 40 ns to 10 s in NR3 format
The :TRIGger:HOLDoff command defines the holdoff time value in seconds. Holdoff keeps a trigger from occurring until after a certain amount of time has passed since the last trigger. This feature is valuable when a waveform crosses the trigger level multiple times during one period of the waveform. Without holdoff, the oscilloscope could trigger on each of the crossings, producing a confusing waveform. With holdoff set correctly, the oscilloscope always triggers on the same crossing. The correct holdoff setting is typically slightly less than one period.
:TRIGger:HOLDoff?
The :TRIGger:HOLDoff? query returns the holdoff time value for the current trigger mode.

:TRIGger[:EDGE]:COUPling
(see page 1164) Command Syntax :TRIGger[:EDGE]:COUPling <coupling>
<coupling> ::= {AC | DC | LFReject}
The :TRIGger[:EDGE]:COUPling command sets the input coupling for the selected trigger sources. The coupling can be set to AC, DC, or LFReject. · AC coupling places a high-pass filter (10 Hz for analog channels, and 3.5 Hz for
all External trigger inputs) in the trigger path, removing dc offset voltage from the trigger waveform. Use AC coupling to get a stable edge trigger when your waveform has a large dc offset. · LFReject coupling places a 50 KHz high-pass filter in the trigger path. · DC coupling allows dc and ac signals into the trigger path.
NOTE
The :TRIGger[:EDGE]:COUPling and the :TRIGger[:EDGE]:REJect selections are coupled. Changing the setting of the :TRIGger[:EDGE]:REJect can change the COUPling setting.

:TRIGger:PATTern
(see page 1164) Command Syntax :TRIGger:PATTern <pattern>
<pattern> ::= <string>[,<edge_source>,<edge>]
<string> ::= "nn...n" where n ::= {0 | 1 | X | R | F} when <base> = ASCii
<string> ::= "0xnn...n" where n ::= {0,..,9 | A,..,F | X | $} when <base> = HEX
<edge_source> ::= {CHANnel<n> | NONE} for DSO models
<edge_source> ::= {CHANnel<n> | DIGital<d> | NONE} for MSO models
<n> ::= 1 to (# of analog channels) in NR1 format
<d> ::= 0 to (# digital channels - 1) in NR1 format
<edge> ::= {POSitive | NEGative}
The :TRIGger:PATTern command specifies the channel values to be used in the pattern trigger. In the <string> parameter, each bit corresponds to a channel as described in the following table:
Oscilloscope Models 4 analog + 16 digital channels (mixed-signal)
2 analog + 16 digital channels (mixed-signal) 4 analog channels only 2 analog channels only
Value and Mask Bit Assignments Bits 0 through 15 - digital channels 0 through 15. Bits 16 through 19 - analog channels 4 through 1. Bits 0 through 15 - digital channels 0 through 15. Bits 16 and 17 - analog channels 2 and 1. Bits 0 through 3 - analog channels 4 through 1. Bits 0 and 1 - analog channels 2 and 1.
The format of the <string> parameter depends on the :TRIGger:PATTern:FORMat command setting: · When the format is ASCii, the string looks just like the string you see on the
oscilloscope's front panel, made up of 0, 1, X (don't care), R (rising edge), and F (falling edge) characters. · When the format is HEX, the string begins with "0x" and contains hex digit characters or X (don't care for all four bits in the nibble).
With the hex format string, you can use the <edge_source> and <edge> parameters to specify an edge on one of the channels.

(see page 1164)
Command Syntax :TRIGger:PATTern:QUALifier <qualifier>
<qualifier> ::= {ENTered | GREaterthan | LESSthan | INRange | OUTRange | TIMeout}
The :TRIGger:PATTern:QUALifier command qualifies when the trigger occurs: · ENTered -- when the pattern is entered. · LESSthan -- when the pattern is present for less than a time value. · GREaterthan -- when the pattern is present for greater than a time value. The
trigger occurs when the pattern exits (not when the GREaterthan time value is exceeded). · TIMeout -- when the pattern is present for greater than a time value. In this case, the trigger occurs when the GREaterthan time value is exceeded (not when the pattern exits). · INRange -- when the pattern is present for a time within a range of values. · OUTRange -- when the pattern is present for a time outside of range of values.
Pattern durations are evaluated using a timer. The timer starts on the last edge that makes the pattern (logical AND) true. Except when the TIMeout qualifier is selected, the trigger occurs on the first edge that makes the pattern false, provided the time qualifier criteria has been met.
Set the GREaterthan qualifier value with the :TRIGger:PATTern:GREaterthan command.

Set the LESSthan qualifier value with the :TRIGger:PATTern:LESSthan command. Set the INRange and OUTRange qualifier values with the :TRIGger:PATTern:RANGe command. Set the TIMeout qualifier value with the :TRIGger:PATTern:GREaterthan command.

The :TRIGger:TV:UDTV:HSYNc command enables or disables the horizontal sync control in the Generic video trigger. For interleaved video, enabling the HSYNc control and setting the HTIMe adjustment to the sync time of the probed video signal allows the ENUMber function to count only lines and not double count during equalization. Additionally, the Field Holdoff can be adjusted so that the oscilloscope triggers once per frame. Similarly, for progressive video with a tri-level sync, enabling the HSYNc control and setting the HTIMe adjustment to the sync time of the probed video signal allows the ENUMber function to count only lines and not double count during vertical sync. This command is available with the DSOX3VID extended Video triggering license.

Introduction to :WAVeform Commands
The WAVeform subsystem is used to transfer data to a controller from the oscilloscope waveform memories. The queries in this subsystem will only operate when the channel selected by :WAVeform:SOURce is on.
Waveform Data and Preamble The waveform record is actually contained in two portions: the preamble and waveform data. The waveform record must be read from the oscilloscope by the controller using two separate commands, :WAVeform:DATA (see page 993) and :WAVeform:PREamble (see page 1000). The waveform data is the actual data acquired for each point in the specified source. The preamble contains the information for interpreting the waveform data, which includes the number of points acquired, the format of acquired data, and the type of acquired data. The preamble also contains the X and Y increments, origins, and references for the acquired data, so that word and byte data can be translated to time and voltage values.
Data Acquisition Types
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
985
32 :WAVeform Commands
There are four types of waveform acquisitions that can be selected for analog channels with the :ACQuire:TYPE command (see page 245): NORMal, AVERage, PEAK, and HRESolution. Digital channels are always acquired using NORMal. When the data is acquired using the :DIGitize command (see page 205) or :RUN command (see page 225), the data is placed in the channel buffer of the specified source. Once you have acquired data with the :DIGitize command, the instrument is stopped. If the instrument is restarted (via the programming interface or the front panel), or if any instrument setting is changed, the data acquired with the :DIGitize command may be overwritten.You should first acquire the data with the :DIGitize command, then immediately read the data with the :WAVeform:DATA? query (see page 993) before changing any instrument setup. A waveform record consists of either all of the acquired points or a subset of the acquired points. The number of points acquired may be queried using :ACQuire:POINts? (see page 238). Helpful Hints: The number of points transferred to the computer is controlled using the :WAVeform:POINts command (see page 996). If :WAVeform:POINts MAXimum is specified and the instrument is not running (stopped), all of the points that are displayed are transferred. This can be as many as 4,000,000 in some operating modes or as many as 8,000,000 for a digital channel on the mixed signal oscilloscope. Fewer points may be specified to speed data transfers and minimize controller analysis time. The :WAVeform:POINts may be varied even after data on a channel is acquired. However, this decimation may result in lost pulses and transitions. The number of points selected for transfer using :WAVeform:POINts must be an even divisor of 1,000 or be set to MAXimum. :WAVeform:POINts determines the increment between time buckets that will be transferred. If POINts = MAXimum, the data cannot be decimated. For example: · :WAVeform:POINts 1000 -- returns time buckets 0, 1, 2, 3, 4 ,.., 999. · :WAVeform:POINts 500 -- returns time buckets 0, 2, 4, 6, 8 ,.., 998. · :WAVeform:POINts 250 -- returns time buckets 0, 4, 8, 12, 16 ,.., 996. · :WAVeform:POINts 100 -- returns time buckets 0, 10, 20, 30, 40 ,.., 990.
Analog Channel Data
NORMal Data Normal data consists of the last data point (hit) in each time bucket. This data is transmitted over the programming interface in a linear fashion starting with time bucket 0 and going through time bucket n - 1, where n is the number returned by the :WAVeform:POINts? query (see page 996). Only the magnitude values of each data point are transmitted. The first voltage value corresponds to the first time bucket on the left side of the screen and the last value corresponds to the
986
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
:WAVeform Commands 32
next-to-last time bucket on the right side of the screen. Time buckets without data return 0. The time values for each data point correspond to the position of the data point in the data array. These time values are not transmitted. AVERage Data AVERage data consists of the average of the first n hits in a time bucket, where n is the value returned by the :ACQuire:COUNt query (see page 236). Time buckets that have fewer than n hits return the average of the data they do have. If a time bucket does not have any data in it, it returns 0. This data is transmitted over the interface linearly, starting with time bucket 0 and proceeding through time bucket n-1, where n is the number returned by the :WAVeform:POINts? query (see page 996). The first value corresponds to a point at the left side of the screen and the last value corresponds to one point away from the right side of the screen. The maximum number of points that can be returned in average mode is 1000 unless ACQuire:COUNt has been set to 1. PEAK Data Peak detect display mode is used to detect glitches for time base settings of 500 us/div and slower. In this mode, the oscilloscope can sample more data than it can store and display. So, when peak detect is turned on, the oscilloscope scans through the extra data, picks up the minimum and maximum for each time bucket, then stores the data in an array. Each time bucket contains two data sample. The array is transmitted over the interface bus linearly, starting with time bucket 0 proceeding through time bucket n-1, where n is the number returned by the :WAVeform:POINts? query (see page 996). In each time bucket, two values are transmitted, first the minimum, followed by the maximum. The first pair of values corresponds to the time bucket at the leftmost side of the screen. The last pair of values corresponds to the time bucket at the far right side of the screen. In :ACQuire:TYPE PEAK mode (see page 245), the value returned by the :WAVeform:XINCrement query (see page 1013) should be doubled to find the time difference between the min-max pairs. HRESolution Data The high resolution (smoothing) mode is used to reduce noise at slower sweep speeds where the digitizer samples faster than needed to fill memory for the displayed time range. Data Conversion Word or byte data sent from the oscilloscope must be scaled for useful interpretation. The values used to interpret the data are the X and Y references, X and Y origins, and X and Y increments. These values are read from the waveform preamble. Each channel has its own waveform preamble. In converting a data value to a voltage value, the following formula is used:
voltage = [(data value - yreference) * yincrement] + yorigin

987
32 :WAVeform Commands
If the :WAVeform:FORMat data format is ASCii (see page 995), the data values are converted internally and sent as floating point values separated by commas. In converting a data value to time, the time value of a data point can be determined by the position of the data point. For example, the fourth data point sent with :WAVeform:XORigin = 16 ns, :WAVeform:XREFerence = 0, and :WAVeform:XINCrement = 2 ns, can be calculated using the following formula:
time = [(data point number - xreference) * xincrement] + xorigin This would result in the following calculation for time bucket 3:
time = [(3 - 0) * 2 ns] + 16 ns = 22 ns In :ACQuire:TYPE PEAK mode (see page 245), because data is acquired in max-min pairs, modify the previous time formula to the following:
time=[(data pair number - xreference) * xincrement * 2] + xorigin Data Format for Transfer There are three formats for transferring waveform data over the interface: BYTE, WORD and ASCii (see ":WAVeform:FORMat" on page 995). BYTE, WORD and ASCii formatted waveform records are transmitted using the arbitrary block program data format specified in IEEE 488.2. When you use the block data format, the ASCII character string "#8<DD...D>" is sent prior to sending the actual data. The 8 indicates how many Ds follow. The Ds are ASCII numbers that indicate how many data bytes follow. For example, if 1000 points will be transferred, and the WORD format was specified, the block header "#800001000" would be sent. The 8 indicates that eight length bytes follow, and 00001000 indicates that 1000 binary data bytes follow. Use the :WAVeform:UNSigned command (see page 1011) to control whether data values are sent as unsigned or signed integers. This command can be used to match the instrument's internal data type to the data type used by the programming language. This command has no effect if the data format is ASCii. Data Format for Transfer - ASCii format
The ASCii format (see ":WAVeform:FORMat" on page 995) provides access to the waveform data as real Y-axis values without using Y origin, Y reference, and Y increment to convert the binary data. Values are transferred as ASCii digits in floating point format separated by commas. In ASCii format, holes are represented by the value 9.9e+37. The setting of :WAVeform:BYTeorder (see page 991) and :WAVeform:UNSigned (see page 1011) have no effect when the format is ASCii. Data Format for Transfer - WORD format
988
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
:WAVeform Commands 32
WORD format (see ":WAVeform:FORMat" on page 995) provides 16-bit access to the waveform data. In the WORD format, the number of data bytes is twice the number of data points. The number of data points is the value returned by the :WAVeform:POINts? query (see page 996). If the data intrinsically has less than 16 bits of resolution, the data is left-shifted to provide 16 bits of resolution and the least significant bits are set to 0. Currently, the greatest intrinsic resolution of any data is 12 bits, so at least the lowest 4 bits of data will be 0. If there is a hole in the data, the hole is represented by a 16 bit value equal to 0. Use :WAVeform:BYTeorder (see page 991) to determine if the least significant byte or most significant byte is to be transferred first. The :BYTeorder command can be used to alter the transmit sequence to match the storage sequence of an integer in the programming language being used.
Data Format for Transfer - BYTE format The BYTE format (see ":WAVeform:FORMat" on page 995 ) allows 8-bit access to the waveform data. If the data intrinsically has more than 8 bits of resolution (averaged data), the data is right-shifted (truncated) to fit into 8 bits. If there is a hole in the data, the hole is represented by a value of 0. The BYTE-formatted data transfers over the programming interface faster than ASCii or WORD-formatted data, because in ASCii format, as many as 13 bytes per point are transferred, in BYTE format one byte per point is transferred, and in WORD format two bytes per point are transferred. The :WAVeform:BYTeorder command (see page 991) has no effect when the data format is BYTE.
Digital Channel Data (MSO models only) The waveform record for digital channels is similar to that of analog channels. The main difference is that the data points represent either DIGital0,..,7 (POD1), DIGital8,..,15 (POD2), or any grouping of digital channels (BUS1 or BUS2). For digital channels, :WAVeform:UNSigned (see page 1011) must be set to ON. Digital Channel POD Data Format Data for digital channels is only available in groups of 8 bits (Pod1 = D0 - D7, Pod2 = D8 - D15). The bytes are organized as:
:WAVeform:SOURce POD1 POD2
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
D7
D6
D5
D4
D3
D2
D1
D0
D15 D14 D13 D12 D11 D10 D9
D8
If the :WAVeform:FORMat is WORD (see page 995) is WORD, every other data byte will be 0. The setting of :WAVeform:BYTeorder (see page 991) controls which byte is 0.

If a digital channel is not displayed, its bit value in the pod data byte is not defined. Digital Channel BUS Data Format Digital channel BUS definitions can include any or all of the digital channels. Therefore, data is always returned as 16-bit values. :BUS commands (see page 247) are used to select the digital channels for a bus.

The binary data is formatted according to the settings of the :WAVeform:UNSigned, :WAVeform:BYTeorder, :WAVeform:FORMat, and :WAVeform:SOURce commands. The number of points returned is controlled by the :WAVeform:POINts command. In BYTE or WORD waveform formats, these data values have special meaning: · 0x00 or 0x0000 -- Hole. Holes are locations where data has not yet been
acquired. Another situation where there can be zeros in the data, incorrectly, is when programming over telnet port 5024. Port 5024 provides a command prompt and is intended for ASCII transfers. Use telnet port 5025 instead. · 0x01 or 0x0001 -- Clipped low. These are locations where the waveform is clipped at the bottom of the oscilloscope display. · 0xFF or 0xFFFF -- Clipped high.

NOTE
The <points_mode> option is deprecated. Use the :WAVeform:POINts:MODE command instead.
Query Syntax
The :WAVeform:POINts command sets the number of waveform points to be transferred with the :WAVeform:DATA? query. This value represents the points contained in the waveform selected with the :WAVeform:SOURce command. For the analog or digital sources, the records that can be transferred depend on the waveform points mode. The maximum number of points returned for math (function) waveforms is determined by the NORMal waveform points mode. See the :WAVeform:POINts:MODE command (see page 998) for more information. Only data visible on the display will be returned. When the :WAVeform:SOURce is the serial decode bus (SBUS1 or SBUS2), this command is ignored, and all available serial decode bus data is returned.
:WAVeform:POINts?
The :WAVeform:POINts query returns the number of waveform points to be transferred when using the :WAVeform:DATA? query. Setting the points mode will affect what data is transferred (see the :WAVeform:POINts:MODE command (see page 998) for more information). When the :WAVeform:SOURce is the serial decode bus (SBUS1 or SBUS2), this query returns the number of messages that were decoded.

(see page 1164) Command Syntax :WAVeform:POINts:MODE <points_mode>
<points_mode> ::= {NORMal | MAXimum | RAW}
The :WAVeform:POINts:MODE command sets the data record to be transferred with the :WAVeform:DATA? query. For the analog or digital sources, there are two different records that can be transferred: · The first is the raw acquisition record. The maximum number of points available
in this record is returned by the :ACQuire:POINts? query. The raw acquisition record can only be transferred when the oscilloscope is not running and can only be retrieved from the analog or digital sources. · The second is referred to as the measurement record and is a 62,500-point (maximum) representation of the raw acquisition record. The measurement record can be retrieved from any source. If the <points_mode> is NORMal the measurement record is retrieved. If the <points_mode> is RAW, the raw acquisition record is used. Under some conditions, such as when the oscilloscope is running, this data record is unavailable. If the <points_mode> is MAXimum, whichever record contains the maximum amount of points is used. Usually, this is the raw acquisition record. But, if the raw acquisition record is unavailable (for example, when the oscilloscope is running), the measurement record may have more data. If data is being retrieved as the oscilloscope is stopped and as the data displayed is changing, the data being retrieved can switch between the measurement and raw acquisition records.
NOTE
If the :WAVeform:SOURce is not an analog or digital source, the only valid parameters for WAVeform:POINts:MODE is NORMal or MAXimum.
Considerations for MAXimum or RAW
data retrieval
· The instrument must be stopped (see the :STOP command (see page 229) or the :DIGitize command (see page 205) in the root subsystem) in order to return more than the measurement record.
· :TIMebase:MODE must be set to MAIN. · :ACQuire:TYPE must be set to NORMal or HRESolution. · MAXimum or RAW will allow up to 4,000,000 points to be returned. The
number of points returned will vary as the instrument's configuration is changed. Use the :WAVeform:POINts? MAXimum query to determine the maximum number of points that can be retrieved at the current settings.

Query Syntax
<r> ::= {1 | 2}
The :WAVeform:SOURce command selects the analog channel, function, digital pod, digital bus, reference waveform, or serial decode bus to be used as the source for the :WAVeform commands. Function capabilities include add, subtract, multiply, integrate, differentiate, and FFT (Fast Fourier Transform) operations. When the :WAVeform:SOURce is the serial decode bus (SBUS1 or SBUS2), ASCii is the only waveform format allowed, and the :WAVeform:DATA? query returns a string with timestamps and associated bus decode information. With MSO oscilloscope models, you can choose a POD or BUS as the waveform source. There are some differences between POD and BUS when formatting and getting data from the oscilloscope: · When POD1 or POD2 is selected as the waveform source, you can choose the
BYTE, WORD, or ASCii formats (see ":WAVeform:FORMat" on page 995). When the WORD format is chosen, every other data byte will be 0. The setting of :WAVeform:BYTeorder controls which byte is 0. When the ASCii format is chosen, the :WAVeform:DATA? query returns a string with unsigned decimal values separated by commas. · When BUS1 or BUS2 is selected as the waveform source, you can choose the WORD or ASCii formats (but not BYTE because bus values are always returned as 16-bit values). When the ASCii format is chosen, the :WAVeform:DATA? query returns a string with hexadecimal bus values, for example: 0x1938,0xff38,...

(see page 1164)
Command Syntax :WAVeform:SOURce:SUBSource <subsource>
<subsource> ::= {{SUB0 | RX | MOSI} | {SUB1 | TX | MISO}}
If the :WAVeform:SOURce is SBUS<n> (serial decode), more than one data set may be available, and this command lets you choose from the available data sets.
When using UART serial decode, this option lets you get "TX" data. (TX is an alias for SUB1.) The default, SUB0, specifies "RX" data. (RX is an alias for SUB0.) When using SPI serial decode, this option lets you get "MISO" data. (MISO is an alias for SUB1.) The default, SUB0, specifies "MOSI" data. (MOSI is an alias for SUB0.)
Query Syntax Return Format
If the :WAVeform:SOURce is not SBUS, or the :SBUS<n>:MODE is not UART or SPI, the only valid subsource is SUB0.

:WGEN:MODulation:NOISe
(see page 1164)
Command Syntax :WGEN:MODulation:NOISe <percent>
Query Syntax Return Format
<percent> ::= 0 to 100
The :WGEN:MODulation:NOISe command adds noise to the currently selected signal. The sum of the amplitude between the original signal and injected noise is limited to the regular amplitude limit (for example, 5 Vpp in 1 MOhm), so the range for <percent> varies according to current amplitude. Note that adding noise affects edge triggering on the waveform generator source as well as the waveform generator sync pulse output signal (which can be sent to TRIG OUT). This is because the trigger comparator is located after the noise source.
:WGEN:MODulation:NOISe?
The :WGEN:MODulation:NOISe query returns the percent of added noise.

:MEASure:TVOLt
(see page 1164) Query Syntax :MEASure:TVOLt? <value>, [<slope>]<occurrence>[,<source>]
<value> ::= the voltage level that the waveform must cross.
<slope> ::= direction of the waveform. A rising slope is indicated by a plus sign (+). A falling edge is indicated by a minus sign (-).
<occurrence> ::= the transition to be reported. If the occurrence number is one, the first crossing is reported. If the number is two, the second crossing is reported, etc.
<source> ::= {<digital channels> | CHANnel<n> | FUNCtion | MATH}
<digital channels> ::= {DIGital<d>} for the MSO models
<n> ::= 1 to (# analog channels) in NR1 format
<d> ::= 0 to (# digital channels - 1) in NR1 format
When the :MEASure:TVOLt? query is sent, the displayed signal is searched for the specified voltage level and transition. The time interval between the trigger event and this defined occurrence is returned as the response to the query. The specified voltage can be negative or positive. To specify a negative voltage, use a minus sign (-). The sign of the slope selects a rising (+) or falling (-) edge. If no sign is specified for the slope, it is assumed to be the rising edge. The magnitude of the occurrence defines the occurrence to be reported. For example, +3 returns the time for the third time the waveform crosses the specified voltage level in the positive direction. Once this voltage crossing is found, the oscilloscope reports the time at that crossing in seconds, with the trigger point (time zero) as the reference. If the specified crossing cannot be found, the oscilloscope reports +9.9E+37. This value is returned if the waveform does not cross the specified voltage, or if the waveform does not cross the specified voltage for the specified number of times in the direction specified. If the optional source parameter is specified, the current source is modified.
NOTE
The :MEASure:TVOLt command is obsolete and is provided for backward compatibility to previous oscilloscopes. Use the :MEASure:TVALue command (see page 470).

IEEE 488.2 defines data structures, commands, and common bit definitions for status reporting (for example, the Status Byte Register and the Standard Event Status Register). There are also instrument-defined structures and bits (for example, the Operation Status Event Register and the Overload Event Register). An overview of the oscilloscope's status reporting structure is shown in the following block diagram. The status reporting structure allows monitoring specified events in the oscilloscope. The ability to monitor and report these events allows determination of such things as the status of an operation, the availability and reliability of the measured data, and more.

· To monitor an event, first clear the event; then, enable the event. All of the events are cleared when you initialize the instrument.
· To allow a service request (SRQ) interrupt to an external controller, enable at least one bit in the Status Byte Register (by setting, or unmasking, the bit in the Service Request Enable register).
The Status Byte Register, the Standard Event Status Register group, and the Output Queue are defined as the Standard Status Data Structure Model in IEEE 488.2-1987. The bits in the status byte act as summary bits for the data structures residing behind them. In the case of queues, the summary bit is set if the queue is not empty. For registers, the summary bit is set if any enabled bit in the event register is set. The events are enabled with the corresponding event enable register. Events captured by an event register remain set until the register is read or cleared. Registers are read with their associated commands. The *CLS command clears all event registers and all queues except the output queue. If you send *CLS immediately after a program message terminator, the output queue is also cleared.

37 Status Reporting
The status register bits are described in more detail in the following tables: · Table 68 · Table 66 · Table 73 · Table 74 · Table 76 · Table 71 · Table 78 The status registers picture above shows how the different status reporting data structures work together. To make it possible for any of the Standard Event Status Register bits to generate a summary bit, the bits must be enabled. These bits are enabled by using the *ESE common command to set the corresponding bit in the Standard Event Status Enable Register. To generate a service request (SRQ) interrupt to an external controller, at least one bit in the Status Byte Register must be enabled. These bits are enabled by using the *SRE common command to set the corresponding bit in the Service Request Enable Register. These enabled bits can then set RQS and MSS (bit 6) in the Status Byte Register.
1134
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
Status Reporting 37
Status Byte Register (STB)
The Status Byte Register is the summary-level register in the status reporting structure. It contains summary bits that monitor activity in the other status registers and queues. The Status Byte Register is a live register. That is, its summary bits are set and cleared by the presence and absence of a summary bit from other event registers or queues. If the Status Byte Register is to be used with the Service Request Enable Register to set bit 6 (RQS/MSS) and to generate an SRQ, at least one of the summary bits must be enabled, then set. Also, event bits in all other status registers must be specifically enabled to generate the summary bit that sets the associated summary bit in the Status Byte Register. The Status Byte Register can be read using either the *STB? Common Command or the programming interface serial poll command. Both commands return the decimal-weighted sum of all set bits in the register. The difference between the two methods is that the serial poll command reads bit 6 as the Request Service (RQS) bit and clears the bit which clears the SRQ interrupt. The *STB? command reads bit 6 as the Master Summary Status (MSS) and does not clear the bit or have any affect on the SRQ interrupt. The value returned is the total bit weights of all of the bits that are set at the present time. The use of bit 6 can be confusing. This bit was defined to cover all possible computer interfaces, including a computer that could not do a serial poll. The important point to remember is that, if you are using an SRQ interrupt to an external computer, the serial poll command clears bit 6. Clearing bit 6 allows the oscilloscope to generate another SRQ interrupt when another enabled event occurs. No other bits in the Status Byte Register are cleared by either the *STB? query or the serial poll, except the Message Available bit (bit 4). If there are no other messages in the Output Queue, bit 4 (MAV) can be cleared as a result of reading the response to the *STB? command. If bit 4 (weight = 16) and bit 5 (weight = 32) are set, the program prints the sum of the two weights. Since these bits were not enabled to generate an SRQ, bit 6 (weight = 64) is not set. The following example uses the *STB? query to read the contents of the oscilloscope's Status Byte Register.
myScope.WriteString "*STB?" varQueryResult = myScope.ReadNumber MsgBox "Status Byte Register, Read: 0x" + Hex(varQueryResult)
The next program prints 0xD1 and clears bit 6 (RQS) and bit 4 (MAV) of the Status Byte Register. The difference in the output value between this example and the previous one is the value of bit 6 (weight = 64). Bit 6 is set when the first enabled summary bit is set and is cleared when the Status Byte Register is read by the serial poll command.

Example The following example uses the resource session object's ReadSTB method to read the contents of the oscilloscope's Status Byte Register.
varQueryResult = myScope.IO.ReadSTB MsgBox "Status Byte Register, Serial Poll: 0x" + Hex(varQueryResult)
NOTE
Use Serial Polling to Read Status Byte Register. Serial polling is the preferred method to read the contents of the Status Byte Register because it resets bit 6 and allows the next enabled event that occurs to generate a new SRQ interrupt.

Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
Status Reporting 37
Service Request Enable Register (SRE)
Example
Setting the Service Request Enable Register bits enable corresponding bits in the Status Byte Register. These enabled bits can then set RQS and MSS (bit 6) in the Status Byte Register. Bits are set in the Service Request Enable Register using the *SRE command and the bits that are set are read with the *SRE? query. The following example sets bit 4 (MAV) and bit 5 (ESB) in the Service Request Enable Register.
myScope.WriteString "*SRE " + CStr(CInt("&H30"))
This example uses the decimal parameter value of 48, the string returned by CStr(CInt("&H30")), to enable the oscilloscope to generate an SRQ interrupt under the following conditions: · When one or more bytes in the Output Queue set bit 4 (MAV). · When an enabled event in the Standard Event Status Register generates a
summary bit that sets bit 5 (ESB).

37 Status Reporting
Trigger Event Register (TER)
This register sets the TRG bit in the status byte when a trigger event occurs. The TER event register stays set until it is cleared by reading the register or using the *CLS command. If your application needs to detect multiple triggers, the TER event register must be cleared after each one. If you are using the Service Request to interrupt a program or controller operation, you must clear the event register each time the trigger bit is set.

Status Reporting 37
Output Queue
The output queue stores the oscilloscope-to-controller responses that are generated by certain instrument commands and queries. The output queue generates the Message Available summary bit when the output queue contains one or more bytes. This summary bit sets the MAV bit (bit 4) in the Status Byte Register. When using the Keysight VISA COM library, the output queue may be read with the FormattedIO488 object's ReadString, ReadNumber, ReadList, or ReadIEEEBlock methods.

37 Status Reporting
Message Queue
The message queue contains the text of the last message written to the advisory line on the screen of the oscilloscope. The length of the oscilloscope's message queue is 1. Note that messages sent with the :SYSTem:DSP command do not set the MSG status bit in the Status Byte Register.
1140
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
Status Reporting 37
(Standard) Event Status Register (ESR)
Example
The (Standard) Event Status Register (ESR) monitors the following oscilloscope status events: · PON - Power On · URQ - User Request · CME - Command Error · EXE - Execution Error · DDE - Device Dependent Error · QYE - Query Error · RQC - Request Control · OPC - Operation Complete
When one of these events occur, the event sets the corresponding bit in the register. If the bits are enabled in the Standard Event Status Enable Register, the bits set in this register generate a summary bit to set bit 5 (ESB) in the Status Byte Register.
You can read the contents of the Standard Event Status Register and clear the register by sending the *ESR? query. The value returned is the total bit weights of all of the bits that are set at the present time.
The following example uses the *ESR query to read the contents of the Standard Event Status Register.
myScope.WriteString "*ESR?" varQueryResult = myScope.ReadNumber MsgBox "Standard Event Status Register: 0x" + Hex(varQueryResult)
If bit 4 (weight = 16) and bit 5 (weight = 32) are set, the program prints the sum of the two weights.
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
1141
37 Status Reporting
(Standard) Event Status Enable Register (ESE)
Example
To allow any of the (Standard) Event Status Register (ESR) bits to generate a summary bit, you must first enable that bit. Enable the bit by using the *ESE (Event Status Enable) common command to set the corresponding bit in the (Standard) Event Status Enable Register (ESE). Set bits are read with the *ESE? query. Suppose your application requires an interrupt whenever any type of error occurs. The error related bits in the (Standard) Event Status Register are bits 2 through 5 (hexadecimal value 0x3C). Therefore, you can enable any of these bits to generate the summary bit by sending:
myScope.WriteString "*ESE " + CStr(CInt("&H3C"))
Whenever an error occurs, it sets one of these bits in the (Standard) Event Status Register. Because all the error related bits are enabled, a summary bit is generated to set bit 5 (ESB) in the Status Byte Register. If bit 5 (ESB) in the Status Byte Register is enabled (via the *SRE command), an SRQ service request interrupt is sent to the controller PC.
NOTE
Disabled (Standard) Event Status Register bits respond but do not generate a summary bit. (Standard) Event Status Register bits that are not enabled still respond to their corresponding conditions (that is, they are set if the corresponding event occurs). However, because they are not enabled, they do not generate a summary bit to the Status Byte Register.
1142
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
Status Reporting 37
Error Queue
As errors are detected, they are placed in an error queue. This queue is first in, first out. If the error queue overflows, the last error in the queue is replaced with error 350, Queue overflow. Any time the queue overflows, the least recent errors remain in the queue, and the most recent error is discarded. The length of the oscilloscope's error queue is 30 (29 positions for the error messages, and 1 position for the Queue overflow message). The error queue is read with the :SYSTem:ERRor? query. Executing this query reads and removes the oldest error from the head of the queue, which opens a position at the tail of the queue for a new error. When all the errors have been read from the queue, subsequent error queries return "0, No error". The error queue is cleared when: · the instrument is powered up, · the instrument receives the *CLS common command, or · the last item is read from the error queue.

The most common example is when an acquisition is started using the :DIGitize, :RUN, or :SINGle commands. Before a measurement result can be queried, the acquisition must complete. Too often fixed delays are used to accomplish this wait, but fixed delays often use excessive time or the time may not be long enough. A better solution is to use synchronous commands and status to know when the oscilloscope is ready for the next request.

Synchronization in the Programming Flow
Most remote programming follows these three general steps: 1 Set up the oscilloscope and device under test (see page 1154). 2 Acquire a waveform (see page 1154). 3 Retrieve results (see page 1154).
Set Up the Oscilloscope
Before making changes to the oscilloscope setup, it is best to make sure it is stopped using the :STOP command followed by the *OPC? query.
NOTE
It is not necessary to use *OPC?, hard coded waits, or status checking when setting up the oscilloscope. After the oscilloscope is configured, it is ready for an acquisition.
Acquire a Waveform
When acquiring a waveform there are two possible methods used to wait for the acquisition to complete. These methods are blocking and polling. The table below details when each method should be chosen and why.
Use When Advantages Disadvantages
Implementation Details
Blocking Wait You know the oscilloscope will trigger based on the oscilloscope setup and device under test. No need for polling. Fastest method. Remote interface may timeout. Device clear only way to get control of oscilloscope if there is no trigger.
See "Blocking Synchronization" on page 1155.
Polling Wait You know the oscilloscope may or may not trigger on the oscilloscope setup and device under test. Remote interface will not timeout No need for device clear if no trigger. Slower method. Requires polling loop. Requires known maximum wait time. See "Polling Synchronization With Timeout" on page 1156.
Retrieve Results
Once the acquisition is complete, it is safe to retrieve measurements and statistics.

Blocking Synchronization
Use the :DIGitize command to start the acquisition. This blocks subsequent queries until the acquisition and processing is complete. For example:

Synchronizing with a Single-Shot Device Under Test (DUT)
NOTE
The examples in "Blocking Synchronization" on page 1155 and "Polling Synchronization With Timeout" on page 1156 assume the DUT is continually running and therefore the oscilloscope will have more than one opportunity to trigger. With a single shot DUT, there is only one opportunity for the oscilloscope to trigger, so it is necessary for the oscilloscope to be armed and ready before the DUT is enabled. The blocking :DIGitize command cannot be used for a single shot DUT because once the :DIGitize command is issued, the oscilloscope is blocked from any further commands until the acquisition is complete.
This example is the same "Polling Synchronization With Timeout" on page 1156 with the addition of checking for the armed event status.

Synchronization with an Averaging Acquisition
When averaging, it is necessary to know when the average count has been reached. The :SINGle command does not average. If it is known that a trigger will occur, a :DIGitize will acquire the complete number of averages, but if the number of averages is large, a timeout on the connection can occur. The example below polls during the :DIGitize to prevent a timeout on the connection.

Command Classifications
To help you use existing programs with your oscilloscope, or use current programs with the next generation of Keysight InfiniiVision oscilloscopes, commands are classified by the following categories: · "Core Commands" on page 1164 · "Non-Core Commands" on page 1164 · "Obsolete Commands" on page 1164
Core Commands
Core commands are a common set of commands that provide basic oscilloscope functionality on this oscilloscope and future Keysight InfiniiVision oscilloscopes. Core commands are unlikely to be modified in the future. If you restrict your programs to core commands, the programs should work across product offerings in the future, assuming appropriate programming methods are employed.
Non-Core Commands
Non-core commands are commands that provide specific features, but are not universal across all Keysight InfiniiVision oscilloscope models. Non-core commands may be modified or deleted in the future. With a command structure as complex as the one for your oscilloscope, some evolution over time is inevitable. Keysight's intent is to continue to expand command subsystems, such as the rich and evolving trigger feature set.
Obsolete Commands
Obsolete commands are older forms of commands that are provided to reduce customer rework for existing systems and programs. Generally, these commands are mapped onto some of the Core and Non-core commands, but may not strictly have the same behavior as the new command. None of the obsolete commands are guaranteed to remain functional in future products. New systems and programs should use the Core (and Non-core) commands. Obsolete commands are listed in: · Chapter 35, "Obsolete and Discontinued Commands," starting on page 1071

Program Message Syntax
To program the instrument remotely, you must understand the command format and structure expected by the instrument. The IEEE 488.2 syntax rules govern how individual elements such as headers, separators, program data, and terminators may be grouped together to form complete instructions. Syntax definitions are also given to show how query responses are formatted. The following figure shows the main syntactical parts of a typical program statement.
1SPHSBN.FTTBHF
":DISPLAY:LABEL ON"
*OTUSVDUJPO)FBEFS 4FQBSBUPS
1SPHSBN%BUB
Instruction Header
Instructions (both commands and queries) normally appear as a string embedded in a statement of your host language, such as Visual Basic or C/C++. The only time a parameter is not meant to be expressed as a string is when the instruction's syntax definition specifies <block data>, such as <learn string>. There are only a few instructions that use block data. Program messages can have long or short form commands (and data in some cases -- see "Long Form to Short Form Truncation Rules" on page 1166), and upper and/or lower case ASCII characters may be used. (Query responses, however, are always returned in upper case.) Instructions are composed of two main parts: · The header, which specifies the command or query to be sent. · The program data, which provide additional information needed to clarify the
meaning of the instruction. The instruction header is one or more mnemonics separated by colons (:) that represent the operation to be performed by the instrument. ":DISPlay:LABel ON" is a command. Queries are indicated by adding a question mark (?) to the end of the header, for example, ":DISPlay:LABel?". Many instructions can be used as either commands or queries, depending on whether or
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide

White Space (Separator)
Program Data
Program Message Terminator
not you have included the question mark. The command and query forms of an instruction usually have different program data. Many queries do not use any program data. There are three types of headers: · "Simple Command Headers" on page 1167 · "Compound Command Headers" on page 1167 · "Common Command Headers" on page 1167 White space is used to separate the instruction header from the program data. If the instruction does not require any program data parameters, you do not need to include any white space. White space is defined as one or more space characters. ASCII defines a space to be character 32 (in decimal). Program data are used to clarify the meaning of the command or query. They provide necessary information, such as whether a function should be on or off, or which waveform is to be displayed. Each instruction's syntax definition shows the program data, as well as the values they accept. "Program Data Syntax Rules" on page 1168 describes all of the general rules about acceptable values. When there is more than one data parameter, they are separated by commas(,). Spaces can be added around the commas to improve readability. The program instructions within a data message are executed after the program message terminator is received. The terminator may be either an NL (New Line) character, an EOI (End-Or-Identify) asserted in the programming interface, or a combination of the two. Asserting the EOI sets the EOI control line low on the last byte of the data message. The NL character is an ASCII linefeed (decimal 10).
NOTE
New Line Terminator Functions. The NL (New Line) terminator has the same function as an EOS (End Of String) and EOT (End Of Text) terminator.
Long Form to Short Form Truncation Rules
To get the short form of a command/keyword: · When the command/keyword is longer than four characters, use the first four
characters of the command/keyword unless the fourth character is a vowel; when the fourth character is a vowel, use the first three characters of the command/keyword. · When the command/keyword is four or fewer characters, use all of the characters.
Long Form RANGe PATTern
Short form RANG PATT

More About Oscilloscope Commands 39
Long Form TIMebase DELay TYPE
Short form TIM DEL TYPE
In the oscilloscope programmer's documentation, the short form of a command is indicated by uppercase characters. Programs written in long form are easily read and are almost self-documenting. The short form syntax conserves the amount of controller memory needed for program storage and reduces I/O activity.
Simple Command Headers
Simple command headers contain a single mnemonic. :AUToscale and :DIGitize are examples of simple command headers typically used in the oscilloscope. The syntax is:
<program mnemonic><terminator>
Simple command headers must occur at the beginning of a program message; if not, they must be preceded by a colon. When program data must be included with the simple command header (for example, :DIGitize CHANnel1), white space is added to separate the data from the header. The syntax is:
<program mnemonic><separator><program data><terminator>
Compound Command Headers
Compound command headers are a combination of two or more program mnemonics. The first mnemonic selects the subsystem, and the second mnemonic selects the function within that subsystem. The mnemonics within the compound message are separated by colons. For example, to execute a single function within a subsystem:
:<subsystem>:<function><separator><program data><terminator>
For example, :CHANnel1:BWLimit ON
Common Command Headers
Common command headers control IEEE 488.2 functions within the instrument (such as clear status). Their syntax is:
*<command header><terminator>
No space or separator is allowed between the asterisk (*) and the command header. *CLS is an example of a common command header.
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
1167
39 More About Oscilloscope Commands
Program Data Syntax Rules
Program data is used to convey a parameter information related to the command header. At least one space must separate the command header or query header from the program data.
<program mnemonic><separator><data><terminator>
When a program mnemonic or query has multiple program data, a comma separates sequential program data.
Character Program Data
Numeric Program Data
<program mnemonic><separator><data>,<data><terminator>
For example, :MEASure:DELay CHANnel1,CHANnel2 has two program data: CHANnel1 and CHANnel2. Two main types of program data are used in commands: character and numeric. Character program data is used to convey parameter information as alpha or alphanumeric strings. For example, the :TIMebase:MODE command can be set to normal, zoomed (delayed), XY, or ROLL. The character program data in this case may be MAIN, WINDow, XY, or ROLL. The command :TIMebase:MODE WINDow sets the time base mode to zoomed. The available mnemonics for character program data are always included with the command's syntax definition. When sending commands, you may either the long form or short form (if one exists). Uppercase and lowercase letters may be mixed freely. When receiving query responses, uppercase letters are used exclusively. Some command headers require program data to be expressed numerically. For example, :TIMebase:RANGe requires the desired full scale range to be expressed numerically. For numeric program data, you have the option of using exponential notation or using suffix multipliers to indicate the numeric value. The following numbers are all equal:
28 = 0.28E2 = 280e-1 = 28000m = 0.028K = 28e-3K.
When a syntax definition specifies that a number is an integer, that means that the number should be whole. Any fractional part will be ignored, truncating the number. Numeric data parameters accept fractional values are called real numbers. All numbers must be strings of ASCII characters. Thus, when sending the number 9, you would send a byte representing the ASCII code for the character 9 (which is 57). A three-digit number like 102 would take up three bytes (ASCII codes 49, 48, and 50). This is handled automatically when you include the entire instruction in a string.

Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
More About Oscilloscope Commands 39
Duplicate Mnemonics
Identical function mnemonics can be used in more than one subsystem. For example, the function mnemonic RANGe may be used to change the vertical range or to change the horizontal range:
:CHANnel1:RANGe .4
Sets the vertical range of channel 1 to 0.4 volts full scale.
:TIMebase:RANGe 1
Sets the horizontal time base to 1 second full scale. :CHANnel1 and :TIMebase are subsystem selectors and determine which range is being modified.
Tree Traversal Rules and Multiple Commands
Command headers are created by traversing down the command tree. A legal command header would be :TIMebase:RANGe. This is referred to as a compound header. A compound header is a header made of two or more mnemonics separated by colons. The mnemonic created contains no spaces. The following rules apply to traversing the tree: · A leading colon (<NL> or EOI true on the last byte) places the parser at the root
of the command tree. A leading colon is a colon that is the first character of a program header. Executing a subsystem command lets you access that subsystem until a leading colon or a program message terminator (<NL>) or EOI true is found. · In the command tree, use the last mnemonic in the compound header as the reference point (for example, RANGe). Then find the last colon above that mnemonic (TIMebase:). That is the point where the parser resides. Any command below that point can be sent within the current program message without sending the mnemonics which appear above them (for example, POSition). The output statements in the examples are written using the Keysight VISA COM library in Visual Basic. The quoted string is placed on the bus, followed by a carriage return and linefeed (CRLF). To execute more than one function within the same subsystem, separate the functions with a semicolon (;):
:<subsystem>:<function><separator><data>;<function><separator><data><ter minator>
For example:
myScope.WriteString ":TIMebase:RANGe 0.5;POSition 0"
Keysight InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide
1169
39 More About Oscilloscope Commands
NOTE
The colon between TIMebase and RANGe is necessary because TIMebase:RANGe is a compound command. The semicolon between the RANGe command and the POSition command is the required program message unit separator. The POSition command does not need TIMebase preceding it because the TIMebase:RANGe command sets the parser to the TIMebase node in the tree.
Example 2: Program Message
Terminator Sets Parser Back to
Root
myScope.WriteString ":TIMebase:REFerence CENTer;POSition 0.00001"
or
myScope.WriteString ":TIMebase:REFerence CENTer" myScope.WriteString ":TIMebase:POSition 0.00001"
NOTE
In the first line of example 2, the subsystem selector is implied for the POSition command in the compound command. The POSition command must be in the same program message as the REFerence command because the program message terminator places the parser back at the root of the command tree.
Example 3: Selecting Multiple
Subsystems
A second way to send these commands is by placing TIMebase: before the POSition command as shown in the second part of example 2. The space after POSition is required. You can send multiple program commands and program queries for different subsystems on the same line by separating each command with a semicolon. The colon following the semicolon enables you to enter a new subsystem. For example:
<program mnemonic><data>;:<program mnemonic><data><terminator>
For example:
myScope.WriteString ":TIMebase:REFerence CENTer;:DISPlay:VECTors ON"
NOTE
The leading colon before DISPlay:VECTors ON tells the parser to go back to the root of the command tree. The parser can then see the DISPlay:VECTors ON command. The space between REFerence and CENter is required; so is the space between VECTors and ON.
Multiple commands may be any combination of compound and simple commands.

Query Return Values
NOTE
Command headers immediately followed by a question mark (?) are queries. Queries are used to get results of measurements made by the instrument or to find out how the instrument is currently configured. After receiving a query, the instrument interrogates the requested function and places the answer in its output queue. The answer remains in the output queue until it is read or another command is issued. When read, the answer is transmitted across the bus to the designated listener (typically a controller). For example, the query :TIMebase:RANGe? places the current time base setting in the output queue. When using the Keysight VISA COM library in Visual Basic, the controller statements:
Dim strQueryResult As String myScope.WriteString ":TIMebase:RANGe?" strQueryResult = myScope.ReadString
pass the value across the bus to the controller and place it in the variable strQueryResult.
Read Query Results Before Sending Another Command. Sending another command or query before reading the result of a query clears the output buffer (the current response) and places a Query INTERRUPTED error in the error queue.
Infinity The representation of infinity is +9.9E+37. This is also the value returned when a Representation measurement cannot be made.

Sequential vs. Overlapped Commands
IEEE 488.2 makes the distinction between sequential and overlapped commands: · Sequential commands finish their task before the execution of the next
command starts. Most oscilloscope commands are sequential. · Overlapped commands run concurrently. Commands following an overlapped command may be started before the overlapped command is completed. Some oscilloscope commands are overlapped. For example, the oscilloscope's save and recall commands are overlapped as well as some commands that perform analysis. With overlapped commands, you can use the *OPC? query to prevent any more commands from being executed until the overlapped command is complete. This may be necessary when a command that follows an overlapped command interferes with the overlapped command's processing or analysis. For example:

VISA COM Example in Python
You can use the Python programming language with the "comtypes" package to control Keysight oscilloscopes. The Python language and "comtypes" package can be downloaded from the web at http://www.python.org/ and http://starship.python.net/crew/theller/comtypes/, respectively. To run this example with Python and "comtypes": 1 Cut-and-paste the code that follows into a file named "example.py". 2 Edit the program to use the VISA address of your oscilloscope. 3 If "python.exe" can be found via your PATH environment variable, open a
Command Prompt window; then, change to the folder that contains the "example.py" file, and enter:
python example.py

VISA Example in C#
To compile and run this example in Microsoft Visual Studio 2008: 1 Open Visual Studio. 2 Create a new Visual C#, Windows, Console Application project. 3 Cut-and-paste the code that follows into the C# source file. 4 Edit the program to use the VISA address of your oscilloscope. 5 Add Keysight's VISA header file to your project:
a Right-click the project you wish to modify (not the solution) in the Solution Explorer window of the Microsoft Visual Studio environment.
b Click Add and then click Add Existing Item... c Navigate to the header file, visa32.cs (installed with Keysight IO Libraries
Suite and found in the Program Files (x86)\IVI Foundation\VISA\WinNT\ Include directory), select it, but do not click the Open button. d Click the down arrow to the right of the Add button, and choose Add as Link. You should now see the file underneath your project in the Solution Explorer. It will have a little arrow icon in its lower left corner, indicating that it is a link. 6 Build and run the program. For more information, see the tutorial on using VISA in Microsoft .NET in the VISA Help that comes with Keysight IO Libraries Suite.
