IEC/IEEE-Bus: Introduction

Remote Control
3.1
Introduction
• UPL may be equipped with option UPL-B4 permitting remote control via an IEC/IEEE-bus interface to
IEC 625.1/IEEE 488.2 standard and an
• RS-232 interface at the COM2 port.
In addition, UPL may be equipped with option UPL-B10 permitting sequence control for automatic
measurements.
Note:
The sections below mainly describe remote control via the IEC/IEEE-bus interface but most of them also
applies to remote control via the RS-232 interface and the Universal Sequence Controller
UPL-B10. If this is not the case reference will be made to the applicable section.
Note:
If the remote-control option UPL-B4 was not originally ordered with the UPL, it may be obtained via the
local sales engineer (for Order No. see data sheet). After entering an enable code as described in the
supplied instructions, the IEC/IEEE-bus option and the RS-232 interface are ready for use without any
additional hardware installations being required.
Note:
If the remote control option UPL-B4 is not enabled, UPL should not be connected to other
instruments via the IEC/IEEE bus as in this case problem-free operation cannot be guaranteed.
The connectors for the IEC/IEEE-bus and the RS-232 interface (COM2) are located at the rear of the
instrument. They allow a controller to be connected for remote control. The instrument supports SCPI
version 1993.0 (Standard Commands for Programmable Instruments). The SCPI standard is based on
standard IEEE 488.2 and aims at the standardization of device-specific commands, error handling and
status registers (see section 3.5.1 SCPI Introduction).
Note:
In the IEC/IEEE-bus command lists given below, all commands confirmed or approved by the SCPI
committee are written in normal characters. Other innovative commands or commands required for
general measurements are in italics and in the form and style as specified by SCPI (not part of SCPI
definition).
This section assumes a basic knowledge of IEC/IEEE-bus programming and controller operation. A
description of the interface commands is to be obtained from the relevant manuals.
The requirements of the SCPI standard placed on command syntax, error handling and configuration of
status registers are explained in detail in the respective sections. Tables provide a fast overview of the
bit assignment in the status registers. The tables are supplemented by a comprehensive description of
the status registers. For detailed program examples of the main functions see 3.15 Examples of
IEC/IEEE-Bus Programming.

IEC/IEEE-Bus: Introduction
UPL
All program examples for IEC/IEEE-bus control are written in R&S BASIC, likewise all program
examples in the UPL software in the paths
C:\UPL\IEC EXAM\EXAM1.BAS ff and
C:\UPL\B10 EXAM\EXAM1.BAS ff.
Examples C:\UPL\IEC EXAM\EXAM1.BAS ff can be directly run on a controller using a suitable
IEC/IEEE-bus card and R&S BASIC. Files with the extension .SAC are setup files required by the
program examples for setting the UPL. Files with the extension .TXT provide the program code of the
examples as an ASCII file and can be accessed by any editor.
Examples C:\UPL\B10 EXAM\EXAM1.BAS ff can be run on an UPL using the Universal Sequence
Controller UPL-B10. Meaning of files with the extensions .SAC and .TXT as described above.

UPL
IEC/IEEE-Bus: First Steps
3.2
First Steps (Read-in of Measured Values)
The short and simple operating sequence below permits rapid setup of the instrument and of its basic
functions.
A condition is, however, that the IEC/IEEE-bus address, which is factory-set to 20, is not changed.
Program example:
Triggering 10 measurement results and display on the screen.
1. Interconnect instrument and controller using the IEC/IEEE-bus cable.
2. Write the following program on the controller and start it with RUN (F2):
10 IEC TERM 10: ’
Controller expects LF as a delimiter of an UPL reply
20 IEC TIME 5000:
’Controller waits max. 5 s for a reply from
30 ’
UPL before sending an IEC/IEEE-bus timeout
40 IEC OUT 20,"*RST": ’
UPL default setup
45 IEC OUT 20,"INP:TYPE GEN2": ’ Internal connection to generator channel 2
50 IEC OUT 20,"*CLS": ’
Resets IEC/IEEE-bus status register
60 FOR I = 1 TO 10
70 IEC OUT 20,"INIT:CONT OFF;*WAI": ’
Triggers a single measurement
80 IEC OUT 20,"SENS:DATA?": ’
Requests a measurement result
90 IEC IN 20, M$:
’Read-in of measurement result
100 PRINT M$:
’Output of measurement result
110 NEXT I
120 END
As a result of the default setup with *RST (see annex A UPL Default Setup in the UPL manual), the
UPL generator produces a 1-kHz sinewave signal with a level of 0.5 V.
Command INP:TYPE GEN2 establishes an internal connection between generator channel 2 and
analyzer channel 1 so that no cabling of outputs and inputs is required for this first test. The UPL
analyzer carries out 10 RMS measurement, indicates the measurement results in the display and
outputs them continuously on the controller display.
Note:
A measurement result must be triggered before it can be displayed on the screen (line 70). The settled
result available after triggering can be requested (line 80), read-in (line 90) and output to the controller
display (line 100).
3. Press the [LOCAL] key on the front panel to return to manual operation.

IEC/IEEE-Bus: Switchover to Remote Control
3.3
UPL
Switchover to Remote Control
After power-on, the instrument is always in the manual operating state (LOCAL state) and can be
operated from the front panel or the keyboard. It is switched to remote control (REMOTE state shown by
REMOTE caption in the screen center) as soon as it receives an addressed command from a controller.
If the UPL has been set to the manual status from REMOTE with the LOCAL key, then each command
via
R&S BASIC switches the UPL to the REMOTE status, because R&S BASIC sends each command in
addressed form to the UPL. If the
NI GPIB device driver is used, the first IEC/IEEE command should be send addressed. This
addressing for board-specific programming is for example the command ibcmd (board address,
20, 1) or for device-specific programming the repeat addressing setting in the NI GPIB device
driver – or ibloc(0) before the first IEC/IEEE command. If the UPL in the LOCAL state is sent a
non-addressed command, the latter will be carried out but the screen will show the old manual
settings and not the expected empty screen with the REMOTE caption.
During remote control, operation from the front panel is disabled. The instrument remains in the remote
state until it is reset to manual operation via the front panel or the IEC/IEEE bus (see section 3.3.3
Return to Manual Operation). Switching from manual operation to remote control and vice versa has no
effect on the instrument setup.

Indications During Remote Control
• The remote-control status is signalled by the word REMOTE in the display center and by the REM
LED on the UPL front panel.
• Measurement results (active) are indicated in the upper part of the display.
• Error messages occurring during IEC/IEEE-bus control are displayed in plain text in the lower part of
the UPL display (see also section 3.14 List of Error Messages).

Return to Manual Operation
Return to manual control can be made from the front panel or via the IEC/IEEE bus.
Manual:
Press the [LOCAL] key, the REM LED goes out.
Prior to the switchover, command processing must be completed as otherwise
remote control is immediately switched on again.
Note: LLO state (Local Lockout):
The [LOCAL] key can be locked by the universal command LLO in order to
prevent inadvertent switchover:
R&S-BASIC:
R&S BASIC command IECLLO
NI-GPIB-Treiber:
NI command SendLLO(0)
This state can be cancelled only by switching the "REN" line of the IEC/IEEE
bus from 0 to 1:
R&S-BASIC:
R&S BASIC commands IECNREN, followed by IECREN.
NI-GPIB-Treiber:
NI commands ibsre(0,0); followed by ibsre(0,1);.

IEC/IEEE-Bus: Messages
3.4
UPL
IEC/IEEE-Bus Messages
The messages transmitted on the data lines of the IEC/IEEE bus can be subdivided into two groups:
• interface messages and
• device-dependent messages
3.4.1
Interface Messages
Interface messages are transmitted on the data lines of the IEC/IEEE bus, with the control line "ATN"
being active. They are used for communication between the controller and the instrument and can only
be sent by a controller with controller function on the IEC/IEEE bus.
There are two groups of interface messages:
• common commands and
• addressed commands
See 3.13.1, Universal Commands and 3.13.2, Addressed Commands
Common commands affect all devices connected to the IEC/IEEE bus without any addressing being
required, whereas addressed commands only affect devices addressed as a listener. The relevant
interface messages for the UPL are listed in annex A.

3.4.2
Device-Dependent Messages (Commands and Responses)
The device-dependent messages are transmitted on the data lines of the IEC/IEEE bus, with the control
line ATN being not active. The ASCII code is used for data transmission. Device-dependent messages
are differentiated according to the direction in which they are sent via the IEC/IEEE bus:
• Commands
are messages sent by the controller to the UPL. They control the device functions
and request information.
The commands are subdivided according to two criteria:
1. According to the effect they have on the device:
Setting commands
cause device settings to be made, e.g. the resetting of
the UPL or the setting of the output level to 1 Volt.
Queries
cause data to be provided for output via the
IEC/IEEE bus, eg for device identification or query of
the active input.
2. According to their definition in the IEEE 488.2 standard:
Common commands are precisely defined in their function and notation in
the IEEE 488.2 standard. They refer to functions as for
instance the management of the standardized status
registers, resetting and selftest
Device-specific
commands
refer to functions that depend on the device
characteristics, such as frequency setting. A large
number of these commands has also been
standardized by the SCPI Consortium (see section
3.5.1 SCPI Introduction)
• Responses
are messages sent by the UPL to the controller following a query. They may
contain results, device settings or information on the device status (see section
3.5.4 Responses to Queries).
The section below describes structure and syntax of device-dependent messages. As from section
3.10 IEC-bus Commands onwards, the commands are listed independent of their function,
described in brief and listed in alphabetical order.

SCPI Introduction
SCPI (Standard Commands for Programmable Instruments) describes a standardized command set for
the programming of instruments regardless of the type of instrument or manufacturer. The goal of the
SCPI Consortium is to standardize device-specific commands to a large extent. For this purpose an
instrument model has been developed which defines identical functions within an instrument or of
different instruments. Command systems have been generated and assigned to these functions so that
it is possible to address identical functions by the same commands. The command systems have a
hierarchical structure. Fig. 3-1 shows this tree structure, using a detail from the SOURce command
system for controlling the signal sources of the instrument. The other examples of syntax and structure
of the commands are taken from this command system.
SCPI is based on the IEEE 488.2 standard, ie it uses the same syntax elements as well as the "common
commands" defined therein. The syntax of the responses is partly subjected to stricter rules than laid
down in the IEEE 488.2 standard).
3.5.2
Command Structure
The commands consist of a so-called header and usually one or several parameters. Header and
parameters are separated by a "white space" (ASCII code 0 to 9, 11 to 32 decimal, eg space). The
headers may be composed of several keywords. The query form is generated by appending a question
mark directly to the header.
Common Commands
Common commands consist of a header preceded by an asterisk "*"
and one or several parameters.
Examples
"*RST"
"*ESE 253"
"*ESR?"
RESET, resets the UPL
EVENT STATUS ENABLE, sets the bits of
the Event Status Enable Registers
EVENT STATUS QUERY, queries the
contents of the Event Status Register.
Universal Sequence Controller (UPL-B10)
RS-232 interface
Common commands to be used can be looked up in Table 3.9 Common Commands.
Device-specific commands
Hierarchy
Device-specific commands have a hierarchical structure (see Fig. 3-1).
The various levels are represented by compound headers. Headers of
the highest level (root level) have one keyword only. This keyword
stands fro a whole command system.
Example:
SENSe
This keyword denotes the command system
SENSe (see section 3.5.7
Programming
Model of UPL Generator)
For lower-level commands the full path has to be specified, starting with
the highest level in the left-most position. The individual keywords are
separated by a colon ":".

Tree structure of SCPI command system, SENSe being shown
as an example
Some command systems permit certain keywords to be optionally inserted
into the header or omitted. In the manual these keywords are marked by
square brackets. For reasons of compatibility with the SCPI standard, the
instrument must be able to recognize the full command length. Some of the
commands become considerably shorter when the optional keywords are
omitted.
Example: "DISPlay[:WINDow]:TEXT[:DATA] ’String’"
The following command has the same effect:
"DISPlay:TEXT ’String’"
(text in graphic display)
The keywords have a long and a short form. The short form or the long
form can be entered, other abbreviations are not permissible
Example: "STATus:QUEStionable:ENABle 1"
The following command has the same effect:
"STAT:QUES:ENAB 1" (0 bit of Status Questionable Register
enabled)
Note:
The short form uses uppercase characters, the long form gives the whole
keyword. Uppercase and lowercase letters are used for identification in the
manual, the UPL itself does not differentiate between uppercase and
lowercase characters.
Parameter:
The parameter must be separated from the header by a "white space". If a
command contains several parameters, they have to be separated by a
comma ",". Some of the queries permit the parameters MINimum and
MAXimum to be entered. For a description of the various types of
parameter see section 3.5.5 Types of Parameters.
Example: "SENSe:FREQuency:STARt? MAXimum"
Response: 21641.8
(query requesting the maximum value for starting a frequency sweep)
Numeric suffix:
If a device has several identical functions or features, eg inputs, the
desired function can be selected by a suffix added to the command.
Example: "SENSe2:Voltage:REFerence 1V"
(reference value for a relative INPUT peak measurement)
Note: Entries without suffix are interpreted like entries with suffix 1

IEC/IEEE-Bus: Structure and Syntax of Messages
3.5.3
Structure of a Command Line
The UPL can process IEC/IEEE-bus commands containing up to 240 characters. If this length is
exceeded, an error message is output.
A command line may take up more than one line on the controller display. The end of a line is
determined by a delimiter.
Delimiters for a command set to the UPL:
A command line to the UPL may contain one or several commands. It is terminated by a
(ASCII code, 10 decimal) or (EOI line active) together with the last useful character of the
command line or by . Since a character (ASCII code, 13 decimal) as a
filler before the delimiter has no effect, the combination is permissible.
Example for generating the various delimiter combinations:
++ (default setting of IEC/IEEE-bus controller):
10 IECEOI
20 IECOUT 20,"XYZ"
If no
’;’ is sent at the line end, is added.
+:
10 IECEOI
20 IECOUT 20,"XYZ"+CHR$(10);
’;’ ensures that no is added.
:
10 IECEOI
20 IECOUT 20,"XYZ";
’;’ ensures that no is added.
:
10 IECNEOI
20 IECOUT 20,"XYZ"+CHR$(10);
’;’ ensures that no is added.
+:
10 IECNEOI
20 IECOUT 20,"XYZ"
If no ’;’ is sent at the line end, is added.

Sequencing of commands:
Commands may be lined up unless they exceed 240 characters in length.
Several commands in a command line are separated by a semicolon
";". If the next command belongs
to a different system, the semicolon is followed by a colon ":"
Example:
IECOUT 20,"SOUR:FREQ:STAR 20Hz;:SYST:BEEP:STAT ON"
(switches on beeper for error messages)
This command line contains two commands. The first command belongs to the SOURce
system and is used to set the start frequency for a generator sweep. The second command
is part of SYSTem and switches on an acoustic alarm in the case of errors.
If the successive commands belong to the same system and therefore have one or several common
levels, the command line may be shortened. The second command following the semicolon then starts
at the level that is below the common levels (see also Fig. 3-1). The colon after the semicolon has to be
omitted.
Example:
IECOUT 20,"SOUR:FREQ:STAR 20Hz;:SYST:BEEP:STAT ON"
(Start- and stop command for sweep)
This command line is shown in full length and contains two commands separated by a
semicolon. Both commands belong to the SOURce command system, FREQency
subsystem, ie they have two common levels.
In the shortened command line the second command starts at the level below
SOURce:FREQ. The colon after the semicolon has to be omitted.
The abbreviated form of the command line is:
IECOUT 20,"SOURce:FREQ:STAR;STOP 15kHz"
A new command line always begins with the complete path.
Example:
IECOUT 20,"SOUR:FREQ:START 20Hz"
IECOUT 20,"SOUR:FREQ:STOP 15 kHz
(Start- and stop command for sweep)
When common commands starting with an asterisk ’*’ are linked in a command string, they are
preceded by a semicolon ’;’ and not by ’;:’ as is the case with linked UPL commands.
Example:
IECOUT 20,"INIT;*WAI;:SENS:DATA1?"

(triggers measurement, selects result of function measurement on channel 1 and sends next command only
after completion of the measurement!)

Responses to Queries
Delimiters of responses sent by the UPL:
All responses sent by the UPL to the IEC/IEEE-bus controller are terminated by (ASCII
code, 10 decimal) and (EOI line active). With the aid of the IECTERM command, the IEC/IEEEbus controller can be set to various delimiters, but only the setting
IECTERM 10 is useful.
• IECTERM 10 causes the IEC/IEEE-bus controller to respond to the delimiter . With
• IECTERM 1 (EOI only) ), the response string from the UPL displayed on the monitor of the IEC/IEEEbus controller is followed by an empty line, as before is interpreted as part of the
response string.
• IECTERM 0 (+), the response string from the UPL displayed on the
monitor of the IEC/IEEE-bus controller will again be followed by an empty line, as the is interpreted as part of the response string and changed into a line feed command by the
IEC/IEEE-bus controller.
All other settings cause a TIMEOUT.

Possible queries
Unless explicitly specified otherwise, a query is defined for each setting command. The query is
generated by appending a question mark to the associated setting command. Some of the SCPI rules
imposed on the query responses are stricter than those of the IEEE 488.2 standard:
1. The requested parameter is sent without header.
Example:
Setting:
"INPut:TYPE BAL"
Query:
"INPut:TYPE?"
Response: BAL
(input BAL for analog analyzer)
2. Maximum and minimum values requested by the character data MAXimum and MINimum are
returned as numeric values
Example:
Setting:
"SENSe:FREQuency MAX|MIN|any value"
Query:
"SENSe:FREQuency? MAX"
Response: 21641.8
Query:
"SENSe:FREQuency? MIN"
Response: 2.0
(maximum or minimum value depend on current setting)
3. Numeric values with floating decimal point are output in the same unit as entered.
Example:
Setting:
"SENSe:FREQuency:STARt 20kHz?"
Query:
"SENSe:FREQuency:STARt?"
Response: 20.0 for 20 kHz
(sweep start frequency)
4. Integral values are returned as such.
Example:
Setting:
"INST:NSEL 1"
Query:
"INST:NSEL?"
Response: 1
(25-kHz analog generator)
5. Text (character data) are returned in short form (see sections 3.5.1 and 3.5.4).
Example:
Setting:
"OUTPut:TYPE BALanced"
Query:
"OUTPut:TYPE?"
Response: BAL
(generator output channel 1 XLR balanced)

6.
Character strings are output in the same way as they are input, ie the simple and
double quotation marks are also output (see section 3.5.6 Overview of Syntax Elements).
Example:
Setting:
"MMEMory:STORe:STATe 2,’LASTSAVE.SCO’"
Response: ’LASTSAVE.SCO’
Query:
"MMEMory:STORe:STATe? 2"
(storage of UPL setting under ’LASTSAVE.SCO’
7. Data blocks are output as ASCII characters or in binary form depending on the IEC/IEEE-bus
commands FORM ASC and FORM REAL.
Example:
Five floating-point values in the form of a trace are available after a sweep.
Setting: "FORM ASC"
Query:
"TRACe? TRACe"
Response: 1.1,1.2,1.3,1.4,1.5
(load Y values of curve A into the UPL)
Setting:
Query:
"FORM REAL"
"TRACe? TRACe"
The response is sent as a binary data stream. Floating-point values are 4 bytes long
and output in the IEEE format (LSB first):
# 2 2 0
--- 1.1 ---
--- 1.2 ---
--- 1.3 ---
--- 1.4 ---
--- 1.5 ---
23 32 32 30 cd cc 8c 3f 9a 99 99 3f 66 66 a6 3f 33 33 b3 3f 00 00 c0 3f
1st value
2nd value
3rd value
4th value
Hexadecimal
form
5th value
Number of following bytes in ASCII. This value divided by 4 yields
the number of the subsequent floating-point values in IEEE format.
Number of digits of subsequently indicated length in ASCII
The ASCII character ’#’ introduces a binary block transfer.
To receive the binary data stream in its full length, set EOI (in R&S-BASIC: IEC
TERM 1) in the controller program and not LF (0Ah = 10d) (in R&S-BASIC: IEC
TERM 10) as would normally be set for the reception of ASCII strings. This is to
avoid the binary data stream being interrupted if the bit combination 0Ah occurs.

Types of Parameters
Most commands require the specification of a parameter. The parameters must be separated from the
header by a "white space" (ASCII code, 0 to 9, 11 to 32 decimal, generally a blank). Parameters may be
specified as numeric values, Boolean parameters, character data, character strings and block data. The
type of parameter required for the specific command as well as the permitted range of values are
described together with the commands (see section 3.10 IEC-bus Commands).
Numeric values
Numeric values may be entered in any customary form, ie with sign, decimal
point and exponent. If the values exceed the resolution of the UPL, they will be
rounded off. The number including the exponent may comprise up to 20
characters. The number of digits of mantissa and exponent is only limited by
this condition. The exponent is denoted by an "E" or "e". The exponent alone
must not be used. Physical quantities may be stated with the unit. Permissible
prefixes for the unit (also called engineering) are M (Mega), K (Kilo), m (milli)
and u (micro). The units for which these prefixes may be used can be seen
from the tables in section 2.4 Units in the UPL manual. With no unit stated,
the basic unit is assumed (see section 3.10 IEC-bus Commands column
Basic unit of UPL manual).
Examples:
"SOURce:FREQuency 1.5 kHz"
1.5E3
1.5E 3
+1.5E3
Special
numeric values
MIN/MAX
1500 Hz
1.5E+3
1.5E 03
001.5E3
The parameters MINimum, MAXimum, UP and DOWN are interpreted as
special numeric values.
MINimum and MAXimum denote the minimum and maximum value.
Upon a query the numeric value will be returned.
Example: Setting command: "SOURce:VOLTage MAXimum"
Query:
"SOURce:VOLTage?"
Response: 24
(maximum generator level)
UP/DOWN
NAN
Boolean parameter
UP increments, DOWN decrements the current numeric value by 0.001%.
Not A Number represents the value 9,91E37, is only sent as a device
response and denotes missing or illegal values.
Boolean parameters represent two states. The on state (true condition) is
represented by ON, the off state (false condition) by OFF.
Example: Setting command: "SENS:FUNC:WEIG ON"
Query:
"SENS:FUNC:WEIG?"
Response: ON
(W&F weighting filter on)
Character data
Character data follow the syntax rules for keywords, ie they also have a short
and a long form. Like any other parameter, they must be separated from the
header by a ’white space’. A query returns the short form of the character data.
Example: Setting command: "DISPlay:MODE COLB"
Query:
"DISPlay:MODE?"
Response: COLB
(Coloured representation on internal and external display)
1078.2008.02

E-10
IEC/IEEE-Bus: Structure and Syntax of Messages
Character string
UPL
According to SCPI strings must always be given in single or double quotation
marks. Normally single quotes are used as the double quotes are used for
identifying the total IEC/IEEE-bus command as a string.
Example: "MMEMory:DELete
’C:\UPL\USER\MYSETUP.SCO’"
(clearing of specified file)
Data strings
Numeric values are to be separated by commas, decimal digits by a ’.’.
Example: "TRAC LIST1, 100.0,1000.0,5000.0,15000.0"
(setting the X values in a graphics display)
"SOUR:LIST:FREQ 1.1,1.2,1.3,1.4,1.5"
(setting the frequencies for a frequency sweep)
Whether the data strings start with a comma or a blank depends on the
command and is defined by SCPI.

Instrument Model and Command Processing
The instrument model shown in the following figure has been configured under the aspect of processing

simultaneously. They communicate with each other by means of so-called messages.

Instrument model with remote control via IEC/IEEE-bus
Input Unit
The input unit receives the commands in the form of characters from the IEC/IEEE bus and collects
them in the input buffer. The input buffer has a capacity of 1024 characters. As soon as the input buffer
is full or receives the interface message DCL, transfer on the IEC/IEEE bus is stopped and the received
data are sent to the parser where the commands are checked for syntax and semantic errors and the
hardware is set in the sequence in which the commands arrived. Data transfer on the IEC/IEEE bus is
then continued. However, if the buffer is not yet full when a terminator is received, the input unit can
receive the next command while the previous command is identified and executed. Reception of a DCL
clears
the
input
buffer.

3.18
E-10
UPL
3.6.2
IEC/IEEE-Bus: Instrument Model and Command Processing
Parser
The parser (to parse = grammatically analyze) analyzes the data received from the input unit proceeding
in the order in which the data are received. A GET (Group Execute Trigger), for example, is only
processed when the previously received commands are executed. A DCL command will be given
priority. Each command identified as correct will immediately be executed and causes a hardware
setting.
Syntax and semantic errors are recognized and passed on to the status reporting system. The
remaining part of a command line after the syntax error will be further analyzed as far as possible and
processed.
While the parser is setting the hardware, the input unit can collect new commands in the input buffer.
This means that further commands can already be processed while settings are being made in the
hardware ("overlapping execution").
3.6.3
Setting the Device Hardware
The term "device hardware" refers to that part of the UPL which performs the instrument function
proper: signal generation, measurements, etc. This does not include the controller.
An IEC/IEEE-bus command line which may contain several setting commands is sent to the parser,
which checks the IEC/IEEE-bus commands for syntax and semantic errors. If a command is identified
as correct, a check is made with the aid of the current settings whether the command is permissible.
Permissible commands are taken over into the UPL data set (corresponds to hardware settings) and
the device hardware is set. If it turns out that the command is illegal because of the existing settings, as
for example a generator level of 20 V on the unbalanced outputs, an "execution error" message is sent
to the status reporting system and no new settings will be made in the device hardware for this
command. Subsequent commands which prove to be permissible are executed as described in the
following section.
This strictly hierarchical sequence ensures that at no time illegal device states will be set.
3.6.4
Why is a Specific Operating Sequence Sometimes Required?
• Each IEC/IEEE-bus command received by the UPL is immediately checked whether it is permissible.
This check can only be carried out if the UPL knows which instrument or function the command is
intended for, ie if the addressed instrument or command has been activated before.
Example1:
Selecting an input impedance of 600 Ohm is permissible for the balanced input, not for the
unbalanced one.
If this check and the respective error messages were to be omitted, measurements would be carried
out with incorrect instrument settings or would not be possible at all and the user would not even
know about it.
Example2:
Setting: generator, unbalanced outputs.
Remote programming of 20 V generator level.
This is not possible, however, as the balanced output allows only 12 V to be set.
–
–
–
–
–
Should the UPL accept this incorrect setting without signalling an error because the user might
afterwards select unbalanced outputs which can handle 20 V.
What will happen when this subsequent selection is not made?
Should the incorrect voltage be output?
Or, should an error message be output when the switchover is not performed?
And when should this error be signalled?
1078.2008.02
3.19
E-10
IEC/IEEE-Bus: Instrument Model and Command Processing
UPL
These conflicts can be avoided by observing the required operating sequence!
• Since similar menu items of different instruments or functions are addressed with the same command
in remote control, they can only be distinguished by a reference to the currently used instrument or
function.
Example:
Command "INPut:SELect CH1" may be used for all 3 analyzer units.
To provide the possibility for presetting also parameters of non-active functions, information on the
instrument or function to be addressed would have to be added to each IEC/IEEE-bus command.
Thus the internal address management of UPL commands would have to be carried out by the
IEC/IEEE-bus programmer. This would make programming unnecessarily difficult and the number of
commands would increase by many times. The UPL uses approx. 6000 menu items which would
then have to be "called up" separately by the user.
• An important operational feature of the UPL is its capability to note the settings for the individual
generator and analyzer functions and to restore all required parameters when one of these functions
is selected.
This eliminates the need to reset each parameter when a new function is selected.
Example:
Settings: Generator, MOD DIST function with frequencies 400 Hz and 7 kHz.
Switchover to DFD function
The frequency pair 11 and 12 kHz, which was set when the DFD function was used last, is
automatically reset.
This function of the UPL is also available for operation via IEC/IEEE bus, ie even in the case of
remote control a function switchover triggers an automatic reset of all pertaining parameters. This is
a much quicker and more reliable than a reset of each parameter every time by the user via IEC/IEEE
bus.
If settings for non-active instruments would be permissible as well, this automatic function could no
longer be used, as in this case already set parameters would also be overwritten.
• As the same internal data sets are used for manual and remote control (combined manual and
remote control should be possible), the same method of internal parameter processing can only be
allowed for the two modes. Since automatic parameter restoration is indispensable for manual
control, it must also be used in the case of remote operation.
To relieve the user from having to pay attention to such not so obvious conditions, the following applies
for manual and remote control of the UPL:
Any setting that is not permissible cannot become effective in the UPL
This has sometimes the disadvantage that a certain sequence has to be observed even in the case of
remote-control. However, this is more than compensated for by the fact that setting errors are
immediately signalled.
Note:
The command logging capability offered by the Universal Sequence Controller for UPL, option UPL-B10,
minimized the risk of incorrect settings (see 3.15.3 Command Logging - Converting B10 into IEC/IEEEBus Commands)

Status Reporting System
The status reporting system collects information on the device status and makes it available to the
output unit on request. Structure and function are described in detail in section 3.7 Status Reporting
System.
3.6.6
Output Unit
The output unit collects the information requested by the controller. It processes such information in line
with the SCPI rules and makes it available in the 1024-character output buffer. If the requested
information is longer it will be made available in blocks in a way that is not noticeable to the controller.
If the UPL is addressed as a talker and the output buffer does not contain any data or expect data from
the data set management, the output unit sends the error message "Query UNTERMINATED" to the
status reporting system. No data will be sent on the IEC/IEEE bus and the controller waits for the set
time limit. This procedure is prescribed by SCPI.
3.6.7
Triggering a Measurement/Sweep
A measurement or a sweep can be triggered in three different ways:
• With the SCPI-specific command
IEC OUT 20,"INIT"
• With the Common Command
IEC OUT 20,"*TRG"
• With the addressed command "Group Execute Trigger" IEC LAD 20: IEC GET
The three trigger modes take about the same execution time.

The addressed GET command is illegal.
Another three commands are available for waiting for a triggered measurement result. They are
described in section 3.6.8.3 Comparison of Synchronization Capabilities. The synchronization
command "*WAI" is used in the program examples below and in 3.15.15.1
Command
Synchronization with *WAI for demonstrating the three trigger modes for a single measurement.
3.6.8
Command Synchronization
There are two events in the UPL, which have to be waited for before the next command can be
executed to make sure that subsequent commands meet clear conditions:
• End of a calibration
• End of a measurement (measurement result ready to be fetched)
Through programming, the controller can be forced to wait for the end of a calibration or measurement
(see table 3-2 Comparison of synchronization capabilities). Commands "*OPC", "*OPC?" or "*WAI"
are used to ensure that a calibration or measurement is completed before a new command is sent (see
section 3.6.8.3 Comparison of Synchronization Capabilities).
In the examples below synchronization by means of the *WAI command is described.

When analog analyzer instruments are called up with commands
IECOUT 20,"INSTrument2 A22;*WAI"
IECOUT 20,"INSTrument2 A110;*WAI"
with calibration switched on in the current setup ("CALibrate:ZERO:AUTO ON")
or upon loading a setup with commands

(current setup)
IECOUT 20,"MMEMory:LOAD:STATe 2, ’filename’;*WAI"

IECOUT 20,"*RST;*WAI"

with calibration switched on in the setup to be loaded ("CALibrate:ZERO:AUTO ON")
or after calling up a calibration with commands
IECOUT 20,"CALibrate:LDG:AUTO ONCE;*WAI" or "CALibrate LDG;*WAI"
IECOUT 20,"CALibrate:ZERO:AUTO ON;*WAI"
or "CALibrate AUTO;*WAI"
IECOUT 20,"CALibrate:ZERO:AUTO ONCE;*WAI" or "CALibrate DCC;*WAI"
Without this forced synchronization, a subsequent generator or analyzer setting command would trigger
a new calibration procedure.
3.6.8.2
Wait for End of Measurement/Sweep
Note:
In the explanations below the term measurement result denotes either a single measurement result or a
sequence of results obtained in a single sweep.
A measurement or a sweep can be triggered by means of INIT , *TRG or GET (see section 3.6.8.2
Wait for End of Measurement/Sweep).
INIT will be used in the examples below.
With IEC/IEEE-bus commands assuming a settled measurement result, synchronization with *WAI,
*OPC? or *OPC must be effected by means of an SRQ. The use of the three synchronization methods
is described in section 3.6.8.3 Comparison of Synchronization Capabilities.
*WAI will be used in the examples below.
The effect of the various combinations of measurement or sweep trigger with a synchronization
command is described in the table below.

Description
A single measurement or sweep is triggered. Subsequent commands are processed
after the measurement or sweep is completed.
Generator and analyzer setting commands do not trigger a new measurement.
A new measurement has to be triggered with
IECOUT 20,"INIT;*WAI".
This command is the simplest to use and should preferably be used for triggering a
measurement.
"INIT:CONT OFF"
without *WAI
When a generator or analyzer setting command is sent during a single measurement,
ie before the measurement is completed, the measurement is restarted to avoid
incorrect results (incorrect results could be obtained, for instance, when the generator
voltage is varied during the measurement).
Generator or analyzer setting commands sent after the single measurement has been
terminated will not trigger a new measurement.
A new measurement has to be triggered with
IECOUT 20,"INIT" .
"INIT:CONT ON;*WAI"
Generator and analyzer setting commands will only be processed when the
measurement is terminated. They will not trigger a new measurements.
A new measurement has to be triggered with
IECOUT 20,"INIT;*WAI" .
"INIT:CONT ON"
without *WAI
Each generator or analyzer setting command restarts a measurement to avoid incorrect
measurement results (incorrect results could be obtained, for instance, when the
generator voltage is varied during the measurement).
Note:
A synchronization of commands other than analyzer, generator, INIT, status loading or calibration
commands is ineffective and should be avoided considering that synchronization commands are .

Status Reporting System
The status reporting system (see Fig. 3-6, Overview of Status Register) stores all information on the
current operating status of the UPL, eg AUTORANGE being performed, and on errors. Such information
is stored in the status registers and in the error queue. The contents of the status registers and of the
error queue can be queried via the IEC/IEEE bus.
The information is hierarchically structured. The topmost level is formed by the Status Byte Register
(STB) defined by IEEE 488.2 and the associated mask register Service Request Enable (SRE). The
STB receives its information from the Standard Event Status Register (ESR) also defined in IEEE 488.2
and the associated mask register Standard Event Status Enable (ESE) as well as from the SCPIdefined STATus:OPERation and STATus:QUEStionable registers and the UPL-specific register
STATus:XQUEstionable, which contain detailed information on the UPL.
The status reporting system also includes the IST flag (Individual STatus) and the Parallel Poll Enable
Register (PPE) assigned to it. The IST flag, just as SRQ, combines the complete device status in a
single bit. The PPE for the IST flag has an analog function like the SRE has for the Service Request.

3.7.1
Structure of SCPI Status Register
The STATus:OPERation Register and the STATus:QUEStionable Register (see section 3.7.3.4
STATus:OPERation Register and) consists of five registers of 16 bits each with different functions (See
Fig. 3-5). The individual bits are independent of each other, ie each hardware status is assigned a bit
number which is the same for all five registers. Bit 5 of the STATus OPERation Registers, for instance,
is assigned in all five registers to the hardware status "wait for trigger". Bit 15 (the most significant bit) is
set to zero in all registers. Thus the contents of the registers can be processed by the controller as a
positive integer.

Status register model
CONDition register
The CONDition register is directly written to by the hardware or the summary
bit of the next lower register. Its contents reflects the current device status.
This register can only be read, but neither written to nor cleared. After an SRQ
has been caused by an entry in one of the status registers, reading the
CONDition register does not trigger another SRQ. Further SRQs are only
possible when the EVENT register of the status register is read.
Reading the register does not change its contents.
PTRansition register
1078.2008.02
The Positive TRansition register acts as a transition filter. Upon transition of a
bit of the CONDition register from 0 to 1, the associated PTR bit decides
whether the EVENt bit will be set to 1
PTR bit = 1: the EVENt bit is set.
PTR bit = 0: the EVENt bit is not set.
This register can be written and read.
Reading the register does not change its contents.
3.25
E-10
IEC/IEEE-Bus: Status Reporting System
NTRansition register
UPL
The Negative TRansition register also acts as a transition filter. Upon
transition of a bit of the CONDition register from 1 to 0, the associated NTR bit
decides whether the EVENt bit is set to 1.
NTR bit = 1: the EVENt bit is set.
NTR bit = 0: the EVENt bit is not set.
This register can be written and read.
Reading the register does not change its contents.
With the aid of these two transition registers the user can define the status
change of the CONDition register (none, 0 to 1, 1 to 0 or both) that is to be
stored in the EVENt register.
EVENt register
The EVENt register reports whether an event has occurred since its last
reading, it is the memory of the CONDition register. It registers events that
have been reported by the transition registers. The EVENt register is
continuously updated by the instrument. It can only be read by the user.
Reading this register clears its contents. After an SRQ has been caused
by an entry in a status register, another SRQ is only possible when the EVENt
register of the status register is read. Reading the CONDition register does
not cause another SRQ.
This register is frequently referred to as the overall register.
ENABle register
The ENABle register determines whether the EVENt bit affects the summary
bit (see below). Each bit of the EVENt register is ANDed (symbol ’&’) with the
associated ENABle bit. The events of all logical operations of this register are
ORed (symbol ’+’) and passed on to the summary bit.
ENAB bit = 0: the associated EVENt bit does not affect the summary bit.
ENAB bit = 1: if the associated EVENt is "1", the summary bit is also
set to "1".
This register can be written and read by the user.
Reading the register does not change its contents.
Summary bit
As stated above, the summary bit for each register is derived from the EVENt
and the ENABle registers. The result is entered into a bit of the CONDition
register of the next higher register.
The instrument automatically generates the summary bit for each register. An
event, eg a non-locking PLL, may thus cause a service request through all
hierarchical levels.
Note:
The Service Request Enable Register SRE defined in IEEE 488.2 may be considered as the ENABle
register of the STB provided that the STB is configured in conformance with SCPI. Accordingly, the ESE
may be considered as the ENABLe register of the ESR.

Description of Status Registers
3.7.3.1
Status Byte (STB) and Service Request Enable Register (SRE)
The STB is already defined in IEEE 488.2. It provides a rough overview of the UPL status, collecting
information from the lower-level registers. It is comparable with the CONDition register of a
SCPI-defined register and is at the highest level of the SCPI hierarchy. Its special feature is that bit 6
acts as the summary bit of all other bits of the Status Byte Register.
The Status Byte Register is read out by the query *STB? or a Serial Poll .
The SRE is associated with the STB. The function of the SRE corresponds to that of the ENABle
register of the SCPI registers. Each bit of the STB is assigned a bit in the SRE. Bit 6 of the SRE is
ignored. If a bit is set in the SRE and the associated bit in the STB changes from 0 to 1, a Service
Request (SRQ) will be generated on the IEC/IEEE bus, which triggers an interrupt in the controller
configured for this purpose, and can be further processed by the controller.
The SRE can be set by the command *SRE and read out by the query *SRE?.
Its contents are not set to zero during reading.
If the EVENt part of a status register is read, the associated bit in the status byte register is deleted (eg
STAT:OPER:EVEN? deletes the OPER bit (d7) in the OPERation register).

Setting of this bit denotes a serious error which can be specified in greater detail by querying the Event Status
Registers with "*ESR?".
6
MSS bit (master status summary bit)
This bit is set if the UPL triggers a service request. This is the case if one of the other bits of this register is set
together with its mask bit in the Service Request Enable Register SRE.
7
OPERation Status Register summary bit
This bit is set if an EVENt bit is set in the OPERation Status Register and the associated ENABle bit is set to 1.
A set bit denotes that an action is just being performed by the UPL. Information on the type of the action can be
obtained by querying the OPERation Status Register with "STATus:OPERation:CONDition?" or
"STATus:OPERation[:EVENt]?".

IEC/IEEE-Bus: Status Reporting System
3.7.4
Use of Status Reporting System
For an efficient use of the status reporting system, the information contained therein has to be
transferred to the controller and further processed. There are various methods which are described in
the following. Detailed program examples are given in 3.15
Examples of IEC/IEEE-Bus
Programming.
3.7.4.1
Service Request, Use of Hierarchical Structure
Under certain conditions, the UPL may send a service request (SRQ) to the controller. This service
request usually causes an interrupt at the controller to which the controller program can respond by a
suitable action. As shown in Fig. 3-6 (Section 3.7.2 Overview of Status Register), a SRQ will always be
triggered if one or several of the bits 3, 5 or 7 have been set in the Status Byte Register and enabled in
the SRE. Each of these bits combines the information from a further status register. By setting the
ENABle registers of the status registers accordingly, any bit in any status register will be able to trigger a
SRQ. To utilize the possibilities of the service request, all bits in the enable registers SRE and ESE
should be set to "1".
Examples:
(see also Fig 3-6 , Section 3.7.2 Overview of Status Register ):
Use command "*OPC" for generating an SRQ. While waiting for the SRQ, the program may perform
other tasks.
• Setting bit 0 (Operation Complete) in the ESE
• Setting bit 5 (ESB) in the SRE
Upon completion of the settings, the UPL generates an SRQ.
Indicating the end of a sweep by an SRQ via bit 3 in the STATus OPERation Register. While waiting for
the SRQ the program may perform other tasks.
• Setting bit 7 (summary bit of STATus:OPERation Register) in the SRE
• Setting bit 3 (Sweep Terminated) in the STATus:OPERation:ENABle Register.
• Setting bit 3 in the STATus:OPERation:NTRansition to ensure that the transition of sweeping bit 3
from 1 to 0 (Sweep-Terminated) is also stored in the EVENt register. Calling up the *CLS command
causes all bits of the NTRansition and PTRansition to be set to 1 so that any bit change is recorded.
Enabling the desired enable bit, in this case bit 3, will normally be sufficient.
After having completed the sweep, the UPL generates an SRQ.
The SRQ is thus the only way for the UPL to become active of its own. A controller program should set
the UPL so that a service request will be generated in case of malfunctions. The program should
suitably respond to the service request. A detailed example of a service request routine is given in
section 3.15.15 Command Synchronization.

Serial Poll
Serial Poll is mainly used for obtaining a quick overview of the status of several devices connected to
the IEC/IEEE bus
In the case of a Serial Poll, the status byte of a device can be queried with
IECOUT 20,"*STB?"
IEC IN 20,A%
However, querying the status byte is normally implemented by interface messages (see annex A,
Interface Messages) which means that a single byte is set to the hardware.
The R&S BASIC command for the execution of a Serial Poll is
IEC SPL 20,A%
It is much quicker than the Common Command "*STB?".
The serial poll method has already been defined in the IEEE 488.1 standard and used to be the only
standard method for querying the status byte of several devices. This method also works with
instruments which neither conform to SCPI nor to IEEE 488.2.

Control via
Parallel Poll
In the parallel poll mode up to eight devices are simultaneously requested by a command from the
controller to transmit 1 bit of information on the assigned data line, ie to pull the assigned data line to
logic 0 or 1. Similar to the SRE register which defines the conditions under which an SRQ will be
generated, there is a Parallel Poll Enable Register (PPE), which is also ANDed bit by bit with the STB –
taking into account bit 6. The result is ORed and is then returned (may be inverted) as a reply to a
parallel poll of the controller. The result can also be read out without parallel poll by the query *IST.
The UPL must first be set for the parallel poll using the R&S BASIC command IEC PCON.
Example:
IECPCON 20,1,6:
UPL identifies itself by a 1 on line 6.
This command assigns a data line to the device on which it sends an SRQ. The parallel poll itself is
made by IEC PPL Pp%.
The parallel poll mode is mainly used to find out quickly which of the devices connected to the IEC/IEEE
bus has caused an SRQ. For this purpose SRE and PPE must be set to the same value. A detailed
example of parallel poll is given in section 3.15.16.1.2 Serial Poll SRQ Routine.

IEC/IEEE-Bus: Status Reporting System
Queries
Each individual register of a status register can be read out by queries. The individual queries are given
in the detailed description of the registers in Section 3.7.3 Description of Status Registers. The queries
always return a number representing the bit pattern of the queried register. This number is evaluated by
the controller program.
Queries are mainly used after a SRQ to obtain detailed information on the cause for the SRQ.
3.7.4.5
Error Queue Query
• Each error condition in the instrument causes an entry in the error queue. The entries in the error
queue are detailed error messages in plain text which can be read out via IEC/IEEE bus by the query
SYSTem:ERRor?. Each query SYSTem:ERRor? returns an entry from the error queue. If there are
no more error messages in the error queue, 0 = "No error" is returned by the instrument
• The error queue should be queried in the controller program after each SRQ since the queue entries
provide a more precise description of the error cause than the status registers. In particular in the test
phase of a controller program the error queue should be queried at regular intervals since it also
registers faulty commands from the controller to the UPL.
Note:
In addition to an entry in the Error Queue, each error causes a plain-text message to be output on the
UPL display so that the IEC/IEEE-bus control program can be checked in the REMOTE control mode
without reading out the Error Queue.

All commands implemented in the UPL according to the command system are tabulated and described
in detail in section 3.10 IEC-bus Commands. The notation is in line with the SCPI standard provided
the committee has defined a command for the required function.
Command table in section 3.10 IEC-bus Commands
Command:
In this column the complete command without parameters is listed.
Parameter:
Here the required parameters and their range of values are stated. If the
command is only available in the form of a query, ’Query only’ is marked in
this column.

Brief description of command.
Reference to the detailed function description in the case of manual
operation, mainly section 2 of the UPL manual.
Upper/lower case
Upper/lowercase characters are used to differentiate between the long
form and the short form of the keywords of a command. The UPL itself
does not distinguish between uppercase and lowercase letters.
Special character |
For some commands there is a choice of keywords having the same effect.
These keywords are stated in the same line and separated by a vertical
bar. Only one of these keywords need to be stated in the header of the
command. The effect of the command is independent of the keyword
selected.
Example:"SOURce:FREQuency:CW|:FIXed"
(setting generator to a constant frequency of 1 kHz)
The two commands below have an identical effect
"SOURce:FREQuency:CW 1E3"≡ "SOURce:FREQuency:FIXed 1E3"
A vertical bar in the notation of the parameters is used to separate
alternative options and is to be seen as "or". The effect of the command
differs according to the parameter stated.
Example:Selection of parameters for the command
"SENSe:VOLTage:UNIT V|DBV|DBU"
(measurement result may be displayed in Volt, dBV or dBu)
Special characters [ ]
Keywords in square brackets may be omitted in compound headers (see
section 3.5.3 Structure of a Command Line). For reasons of compatibility
with the SCPI standard, the instrument must be able to accept the full
length of the command.
Parameters in square brackets may also be optionally inserted in the
command or omitted.
Example: "SENSe[1][:VOLTage|POWer]:REFerence:MODE ..."
has the same effect as
"SENSe:REFerence:MODE ..."

*OPC
OPERATION COMPLETE sets bit 0 in the Event Status Register if all preceding commands have
been executed. This bit may be used to assert a Service Request (see section 3.6.8.3 Comparison
of Synchronization Capabilities, 3.7.3.3 Event Status Reg. (ESR), Event Status Enable Reg. (ESE),
and section 3.15.15.3 Command Synchronization with *OPC and SRQ
*OPC?
OPERATION COMPLETE QUERY places an ASCII character "1" in the output buffer as soon as all
preceding commands have been executed (see 3.6.8.3 Comparison of Synchronization Capabilities
and section 3.15.15.3 Command Synchronization with *OPC and SRQ.
*PCB 0 to 30
PASS CONTROL BACK notifies the address of the controller to which the IEC/IEEE-bus control is to
returned.
*PRE 0 to 255
PARALLEL POLL REGISTER ENABLE sets the Parallel Poll Enable Register to the defined value.
The query *PRE? returns the contents of the Parallel Poll Enable Registers in decimal form
*RST
RESET sets the UPL to a defined default state. The parameter-Link (see 2.15.8 Transfer of
Parameters (Parameter Link Function)) is switched off to ensure that the default state as described
in Annex A UPL Default Setup is maintained after a change of instrument or function.
*SRE 0...255
SERVICE REQUEST ENABLE sets the Service Request Enable Register to the defined value. Bit 6
(MSS mask bit) remains 0. This command determines the conditions under which a Service Request
will be asserted. The query *SRE? outputs the contents of the Service Request Enable Registers in
decimal form.
Bit 6 is always 0.
*STB?
READ STATUS BYTE QUERY outputs the contents of the status byte in decimal form.
Its contents are not set to zero during reading.
If the EVENt part of a status register is read, the associated bit in the status byte register is deleted
(eg STAT:OPER:EVEN? deletes the OPER bit (d7) in the OPERation register).
*TRG
TRIGGER starts all actions waiting for a trigger event.
See sections 3.6.7 Triggering a Measurement/Sweep; 3.6.8.2 Wait for End of Measurement/Sweep
and section 3.15.8.1 Readout of Triggered Measurements.
*TST?
SELF TEST QUERY causes a brief selftest of the UPL and outputs an error code in decimal form (’0’
for ok., ’1’ for error)
*WAI
WAIT-to-CONTINUE allows processing of commands only after all preceding commands have been
executed, all signals settled and current measurements are terminated (see sections 3.6.8.2 Wait

far as possible to the input signal. Maximum algorithmic error:
→ 1%
→ 1‰.
→ A special mode is available for RMS measurements, permitting a single
delay-free measurement with selectable measurement time to be carried
out as soon as the signal exceeds a set trigger threshold for the first
time.In conjunction with the generator burst signal this measurement
mode permits the first period of a signal to be measured and is particularly
suitable for echo-free measurements on loudspeakers.
→ Measurement over (at least) one whole period of the generator signal. If
required, the generator frequency is matched to the analyzer sampling
rate. In the case of high frequencies the measurement time is extended to
several periods to increase the measurement accuracy. Particularly
suitable for measuring very noisy or distorted signals and for extremely
fast sweeps. This measurement method guarantees maximum
measurement accuracy at minimum measurement times and should
therefore be given preference.
If the MODDIST signal is used as generator signal, the measurement time
is referred to the LOWER Frequency, which normally dominates.
