SCPI Command Overview
SCPI (Standard Commands for Programmable Instruments) is a standardized instrument programming
language that is built upon the standard IEEE488.1 and IEEE 488.2 and conforms to various standards
(such as the floating point operation rule in IEEE754 standard, ISO646 7-bit coded character for
information interchange (equivalent to ASCll programming)). The SCPI commands provide a hierarchical
tree structure. Each command subsystem consists of a root keyword and on or more sub-keywords.

Syntax
The command string usually starts with ":"; the keywords are separated by ":" and are followed by the
parameter settings available; "?" is added at the end of the command string to indicate query; the
command and parameter are separated by space.
For example,
:ACQuire:TYPE
:ACQuire:TYPE?
ACQuire is the root keyword of the command. TYPE is the second-level keyword. The command string starts
with ":" which is also used to separate the multiple-level keywords. represents the parameters
available for setting. "?" represents query. The command :ACQuire:TYPE and parameter are
separated by space.
"," is generally used for separating multiple parameters contained in the same command, for example,
:TRIGger:PATTern:PATTern ,,,

Symbol Description
The following symbols will not be sent with the commands.
1.

Braces {}
The parameters enclosed in the braces are optional and are usually separated by the vertical bar "|".
When using the command, one of the parameters must be selected.

Vertical Bar |
The vertical bar is used to separate multiple parameters and one of the parameters must be selected
when using the command.

Square Brackets []
The content in the square brackets can be omitted.

Triangle Brackets <>
The parameter enclosed in the triangle brackets must be replaced by an effective value.

Chapter 1 Programming Overview

Parameter Type
1.

Bool
The parameter could be OFF, ON, 0 or 1. For example,
:MEASure:ADISplay
:MEASure:ADISplay?
Wherein,
can be set to {{0|OFF}|{1|ON}}.
The query returns 0 or 1.

Discrete
The parameter could be any of the values listed. For example,
:ACQuire:TYPE
:ACQuire:TYPE?
Wherein,
can be set to NORMal|AVERages|PEAK|HRESolution.
The query returns the abbreviations (NORM, AVER, PEAK or HRES).

Integer
Unless otherwise noted, the parameter can be any integer (NR1 format) within the effective value
range. Note that do not set the parameter to a decimal, otherwise errors will occur. For example,
:DISPlay:GBRightness
:DISPlay:GBRightness?
Wherein,
can be set to any integer between 0 and 100.
The query returns an integer between 0 and 100.

Real
The parameter can be any real number within the effective value range and this command accepts
decimal (NR2 format) and scientific notation (NR3 format) parameter input. For example,
:TRIGger:TIMeout:TIMe
:TRIGger:TIMeout:TIMe?
Wherein,
can be set to any real number between 1.600000e-08 (namely 16ns) to 0.1e+02 (namely 10s).
The query returns a real number in scientific notation.

ASCII String
The parameter should be the combinations of ASCII characters.
For example,
:SYSTem:OPTion:INSTall
Wherein,
can be set to PDUY9N9QTS9PQSWPLAETRD3UJHYA.

Command Abbreviation
All the commands are case-insensitive and you can use any of them. If abbreviation is used, all the capital
letters in the command must be written completely. For example, the :MEASure:ADISplay? command can
be abbreviated to :MEAS:ADIS?.

RIGOL

Chapter 2 Command System

:AUToscale
Syntax

:AUToscale

Description

Enable the waveform auto setting function. The oscilloscope will automatically adjust the
vertical scale, horizontal timebase and trigger mode according to the input signal to
realize optimum waveform display. This command is equivalent to pressing the AUTO key
at the front panel.

Explanation



Theoretically, waveform auto setting function requires that the frequency of sine is no
lower than 41Hz; the duty cycle should be greater than 1% and the amplitude must
be at least 20mVpp for square.



When the pass/fail function is enabled (see the :MASK:ENABle command), if you sent
this command, the oscilloscope will disable the pass/fail function firstly and then
execute the waveform auto setting function.



When the waveform record function is enabled or during the playback of the
recorded waveform, this command is invalid.

:CLEar
Syntax
Description

Related
Command

:CLEar
Clear all the waveforms on the screen. If the oscilloscope is in the RUN state, waveform

AUTO



When a single channel is on: {AUTO|12000|120000|1200000|12000000|24000000}
When dual channels are on: {AUTO|6000|60000|600000|6000000|12000000}
When four channels are on: {AUTO|3000|30000|300000|3000000|6000000}
Wherein, 24000000, 12000000 and 6000000 are options.



The relationship among the memory depth, sample rate and waveform length
satisfies the following equation:
Memory Depth ＝ Sample Rate × Waveform Length
Wherein, the Waveform Length is the product of the horizontal timebase (set by
the :TIMebase[:MAIN]:SCALe command) times the number of the horizontal scales
(12 for DS1000Z).
When AUTO is selected, the oscilloscope will select the memory depth automatically
according to the current sample rate.

{NORMal|AVERages|PEAK|HRESolution}

NORMal



NORMal: in this mode, the oscilloscope samples the signal at equal time interval to
rebuild the waveform. For most of the waveforms, the best display effect can be
obtained using this mode.



AVERages: in this mode, the oscilloscope averages the waveforms from multiple
samples to reduce the random noise of the input signal and improve the vertical
resolution. The number of averages can be set by the:ACQuire:AVERages command.
The greater the number of averages is, the lower the noise will be and the higher the
vertical resolution will be but the slower the response of the displayed waveform to
the waveform changes will be.



PEAK (Peak Detect): in this mode, the oscilloscope acquires the maximum and
minimum values of the signal within the sample interval to get the envelope of the
signal or the narrow pulse of the signal that might be lost. In this mode, signal
confusion can be prevented but the noise displayed would be larger.



HRESolution (High Resolution): this mode uses a kind of ultra-sample technique to
average the neighboring points of the sample waveform to reduce the random noise
on the input signal and generate much smoother waveforms on the screen. This is
generally used when the sample rate of the digital converter is higher than the
storage rate of the acquisition memory.

The query returns NORM, AVER, PEAK or HRES.

:ACQuire:SRATe?
Syntax

:ACQuire:SRATe?

Description

Query the current sample rate. The default unit is Sa/s.

Explanation



Sample rate is the sample frequency of the oscilloscope, namely the waveform points
sampled per second.



The relationship among the memory depth, sample rate and waveform length
satisfies the following equation:
Memory Depth ＝ Sample Rate × Waveform Length
Wherein, the Memory Depth can be set using the :ACQuire:MDEPth command, and
the Waveform Length is the product of the horizontal timebase (set by
the :TIMebase[:MAIN]:SCALe command) times the number of the horizontal scales
(12 for DS1000Z).

Syntax

:DISPlay:DATA?

Description

Read the bitmap data stream of the image currently displayed.

Explanation

The command is sent from the PC to the instrument through the VISA interface. The
instrument responds to the command and directly returns the bitmap data stream of the
image currently displayed to the buffer area of the PC.

Return
Format

Th format of the bitmap data stream is as follows.
Component

TMC
Blockheader

Size
(length)

Example

Explanation

N[1]+2

#9001152054

TMC Blockheader ::= #NXXXXXX is
used to describe the length of the
data stream. Wherein, # is the start
denoter of the data stream; N is less
than or equal to 9 and the N figures
following it denote the length of the
data stream in bytes. For example,
#9001152054; wherein, N is 9 and
001152054 denotes that the data
stream contains 1152054 bytes of
effective data.

800*480*3+
54=1152054

BM…

Specific bitmap data.

[2]

Note[1]: N is the width used to describe the data length in the TMC header. For example,
#90000.
Note[2]: The width is 800, the height is 480, the bit depth is 24 bit = 3 byte, 54 is the size
of the bitmap file header.
Example

2-30

Make sure that the buffer is large enough to receive the data stream, otherwise the
program might be abnormal when reading the data stream.

The returned data stream contains the TMC data header which should be removed to
make the data stream a standard bitmap data stream.

When the data size is larger than 1 M and the communication speed of the interface
is not fast enough, you need to set an appropriate timeout time.

The terminator '\n'(0X0A) at the end of the data should be removed.

The :MATH commands are used to set the operations between the waveforms of multiple channels.
Note:
 The operations can be divided into two types.
Analog Operations: A+B, A-B, A×B, A/B, FFT, intg, diff, sqrt, lg, ln, exp and abs
Logic Operation: A&&B, A||B, A^B and !A
 For the logic operation, the waveform data to be operated is compared with the preset threshold and is
converted to 0 or 1. Thus, the result will also be 0 or 1.
 For the analog operation or logic operation which needs only one source, only the :MATH:SOURce1
command will be used.

is negative. The area measured is the algeraic sum of the area of the waveform within the whole period.
Note that when the waveform on the screen is less than a period, the period area measured is 0.

When the align phase operation is performed, the instrument re-configures the two
channels to make them output with the specified frequency and phase.
For two signals whose frequencies are the same or in multiple, this operation will align
their phases. For example, assume Source1 output a 1kHz, 5Vpp, 0° sine waveform and
Source2 outputs a 1kHz, 5Vpp, 180° sine waveform. Sample the two waveforms using
another oscilloscope and display them stably; you will see that the waveforms shown on
the oscilloscope do not always have a phase deviation of 180°. At this point, execute the
align phase operation and the waveforms shown on the oscilloscope will have a phase
deviation of 180° without any manual adjustment of the start phase of the generator.

500ns

The maximum of is the main timebase scale currently set and the
minimum is related to the current sample rate (satisfying the inequality: current
sample rate * delayed timebase scale * 7 ≥ 14) and is no less than 1ns.
The delayed timebase scale can only be the maximum or the value decreased
from the maximum in 1-2-5 step. If the minimum calculated by the inequality
mentioned above is not a settable value, the larger settable value that is nearest
to the calculated value will be used as the minimum. If the value set is between
two settable values, the smaller one will be used as the delayed timebase scale
automatically.
For example, when the main timebase scale currently set is 10.00μs and the
sample rate is 500MSa/s, the maximum of is 10.00μs. The
minimum is calculated using the inequality: ≥ 14 / (500MSa/s * 7) = 40ns. Taking
the larger settable value that is nearest to the calculated value, the minimum is
50ns. At this point, if 0.000009 (namely 9μs) is set, the instrument sets the
delayed timebase scale to 5μs.

16ns



Trigger holdoff can be used to stably trigger the complex waveforms (such as pulse
series). Holdoff time is the time that the oscilloscope waits before re-arming the
trigger circuitry. The oscilloscope will not trigger until the holdoff time expires.



When the trigger type is video, RS232, I2C or SPI, this setting will be not available.

The query retuns the trigger holdoff time in scientific notation.

Matlab Programming Demo
The program used in this demo: MATLAB R2009a
The function realized in this demo: make FFT operation on the waveform data and draw the
waveform.
1.

Run the Matlab software and modify the current directory (namely modify the Current Directory at
the top of the software). In this demo, the current directory is modified to E:\DS1000Z_Demo.

Click File  New  Blank M-File in the Matlab interface to create an empty M file.

Add the following codes in the M file:
% Create VISA object
DS1000z = visa('ni','USB0::0x1AB1::0x04CE::DS1T00000006::INSTR');
% Set the device property. In this demo, the length of the input buffer is set to 2048.
DS1000z.InputBufferSize = 2048;
% Open the VISA object created
fopen(DS1000z);
% Read the waveform data
fprintf(DS1000z, ':wav:data?' );
% Request the data
[data,len]= fread(DS1000z,2048);
% Close the VISA object
fclose(DS1000z);
delete(DS1000z);
clear DS1000z;
% Data processing. The waveform data read contains the TMC header. The length of the header is 11
bytes, wherein, the first 2 bytes are the TMC header denoter (#) and the width descriptor (9)
respectively, the 9 bytes following are the length of the data which is followed by the waveform data
and the last byte is the terminator (0x0A). Therefore, the effective waveform points read is from the
12nd to the next to last.
wave = data(12:len-1);
wave = wave';
subplot(211);
plot(wave);
fftSpec = fft(wave',2048);
fftRms = abs(fftSpec');
fftLg = 20*log(fftRms);

Chapter 3 Programming Demos

Open the Block Diagram interface. Right-click on the VISA resource name and you can select and
add the following functions from VISA Palette from the pop-up menu: VISA Write, VISA Read,
VISA Open and VISA Close.

Connect the VISA resource name with the VISA Open. Then, connect the VISA resource name
outputs of all the functions with the VISA resource name and connect the error output with the
error input as shown in the figure below.

Add text boxes in the write buffer areas of the VISA Write control and input “:WAV:SOR CH1”,
":WAV:FORM BYTE" and ":WAV:DATA CHAN1" respectively. The first sets the channel source to CH1,
the second sets the waveform reading format to BYTE and the last reads the screen waveform data.
Waveform data is read through the VISA Read function which requires users to input the total
number of bytes to be read. In this example, the total number of bytes of waveform data to be read is
less than 2048. Close the VISA resource after the VISA operation is finished.

The data format is TMC header + waveform data points + terminator. The TMC header is in #NXXXXXX
format, wherein, # is the TMC header denoter, N represents that there are N bytes following. The
length of the waveform data points is described in ASCII character, and the terminator represents the
ending of the communication. For example, for #9000001200XXXX, 9 bytes are used to describe the
length of the data, 000001200 represents the length of the waveform data (namely 1200 bytes). Use
the String Subset and Decimal String To Number functions to get the value of N.
