Chapter 1 SCPI Command Overview RIGOL
DS4000E Programming Guide 1-1
Chapter 1 SCPI Command Overview
This chapter introduces the syntax, symbols, parameters, and abbreviation rules of the SCPI commands.
Contents in this chapter:
Syntax
Symbol Description
Parameter Type
Command Abbreviation
Syntax
The SCPI commands provide a hierarchical tree structure, and consist of multiple subsystems. Each
command subsystem consists of one root keyword and one or more sub-keywords. The command line
usually starts with a colon; the keywords are separated by colons, and following the keywords are the
parameter settings available. The command ending with a question mark indicates querying a certain
function. The keywords of the command and the first parameter is separated by a space.
For example,
:CALCulate:ADVanced:EXPRession <str>
:CALCulate:ADVanced:EXPRession?
CALCulate is the root keyword of the command. ADVanced is the second-level keyword, and EXPRession is
the third-level keyword. The command line starts with a colon, and a colon is also used to separate the
multiple-level keywords. <str> represents the parameters available for setting. The command line ending
with a question mark indicates that it is a query command.
The command :CALCulate:ADVanced:EXPRession and the parameter <str> are separated by a space.
In some commands with multiple parameters, commas are often used to separate these parameters. For
example,
:SYSTem:DATE <year>,<month>,<day>.
Symbol Description
1. Braces { }
The contents enclosed in the braces are parameter options, which are usually separated by the vertical
bar "|". When using the command, you must select one of the parameter options.
2. Vertical Bar |
The vertical bar is used to separate multiple parameter options. When using the command, you must
select one of the parameter options.
3. Square Brackets [ ]
The contents in the square brackets can be omitted.
4. Angle Brackets < >
The parameter enclosed in the angle brackets must be replaced by an effective value.

RIGOL Chapter 1 SCPI Command Overview
1-2 DS4000E Programming Guide
Parameter Type
1. Bool
The available values for the parameter is 1 (ON) or 0 (OFF). For example,
:MEASure:ADISplay <bool>
:MEASure:ADISplay?
Wherein, <bool> can be set to {{1|ON}|{0|OFF}}.
The query returns 1 or 0.
2. Discrete
The parameter can be any of the values listed. For example,
:ACQuire:TYPE <type>
:ACQuire:TYPE?
Wherein, <type> can be set to NORMal, AVERages, PEAK, or HRESolution.
The query returns NORM, AVER, PEAK, or HRES.
3. Integer
Unless otherwise specified, the parameter can be any integer within the effective value range. Do not
set the parameter to a decimal or in scientific notation, otherwise, errors will occur. For example,
:DISPlay:GBRightness <bright>
:DISPlay:GBRightness?
Wherein, <brightness> can be set to an integer between 0 and 100.
The query returns an integer between 0 and 100.
4. Real
The parameter can be any real-value (in decimal form or in scientific notation) within the effective
value range. For example,
:FUNCtion:WREPlay:INTerval <interval>
:FUNCtion:WREPlay:INTerval?
Wherein, <interval> can be set to any real number between 0.0000001 and 10; or any real number
between (1.000000e-07, namely 100 ns) and (0.1e+02, namely 10 s).
The query returns a real number in scientific notation.
5. ASCII String
The parameter can be the combinations of ASCII characters. For example,
:CALCulate:ADVanced:EXPRession <str>
:CALCulate:ADVanced:EXPRession?
Wherein, <str> can be set to a legitimate expression that consists of any combinations of CH1, CH2,
CH3, CH4, and operators. For example, CH1+CH2.
The query returns in strings.
Command Abbreviation
All the commands are case-insensitive. The commands can be all input in uppercase letters or in lowercase

Note:
1. Unless otherwise specified, the descriptions and parameter range in this manual all take DS4024E as
an example.
2. For the parameter setting command (time, frequency, amplitude, etc.), the digital oscilloscope can
only recognize the numbers, unable to recognize the unit sent together with them. The unit of the
parameter is a default one. For the default units of various parameters, refer to the descriptions for the
specified command.
:AUToscale
Syntax
:AUToscale
Description
Enables the waveform auto setting function. The oscilloscope will automatically adjust the parameters such
as vertical scale, horizontal time base, and trigger mode according to the input signal to realize an optimum
waveform display. This command functions the same as the AUTO key on the front panel.
Remarks
When the waveform auto setting function is disabled (refer to the :SYSTem:AUToscale command), this
command is invalid.

RIGOL Chapter 2 Command System
2-2 DS4000E Programming Guide
When the pass/fail test function is enabled (refer to the :MASK:ENABle command), this command is
invalid.
The waveform auto setting function requires that the frequency of sine waveform is no less than 20 Hz,
the duty cycle is greater than 1%, and the amplitude is at least 20 mVpp. Otherwise, the waveform
auto setting function may be invalid.
:CLEar
Syntax
:CLEar
Description
Clears all the waveforms on the screen. If the oscilloscope is in the RUN state, after the waveform data is
cleared, new waveform data will be displayed. This command functions the same as the CLEAR key on the
front panel.
:RUN
:STOP
Syntax
:RUN
:STOP
Description
The :RUN command starts the oscilloscope and the :STOP command stops the oscilloscope. This command
functions the same as the Run/Stop key on the front panel.
Remarks
If the oscilloscope is in a single trigger mode (refer to the :SINGle command), you can use the :RUN
command to set the trigger mode of the oscilloscope to "Auto", and keep the oscilloscope in the "Run" state.
If the oscilloscope is in a single trigger mode (refer to the :SINGle command) and in WAIT state, you can
use the :STOP command to set the trigger mode of the oscilloscope to "Auto", and keep the oscilloscope in
the "Stop" state.
:SINGle
Syntax
:SINGle
Description
Sets the trigger mode of the oscilloscope to "Single". This command functions the same as the Single key
on the front panel.
Remarks
In the single trigger mode, the oscilloscope performs a single trigger when the trigger conditions are
met and then it stops. You can use the :TFORce command to generate a trigger by force.
If the oscilloscope is in a single trigger mode, you can use the :RUN command to set the trigger mode
of the oscilloscope to "Auto", and keep the oscilloscope in the "Run" state.
If the oscilloscope is in a single trigger mode and in WAIT state, you can use the :STOP command to
set the trigger mode of the oscilloscope to "Auto", and keep the oscilloscope in the "Stop" state.

:TFORce
Syntax
:TFORce
Description
Generates a trigger signal forcefully. This command is only applicable to the normal and single trigger
modes, refer to the :TRIGger:SWEep command. This command functions the same as the FORCE key in
the trigger control area of the front panel.
:TLHAlf
Syntax
:TLHAlf
Description
Sets the trigger level to the vertical midpoint of the amplitude of a trigger signal. This command functions
the same as the 50% key in the trigger control area of the front panel.

:ACQuire Commands
Command List[1]:
:ACQuire:AALias
:ACQuire:AVERages
:ACQuire:MDEPth
:ACQuire:SRATe?
:ACQuire:TYPE
Note[1]:In the "Command List" in this manual, the query commands and the parameters in the setting commands are
omitted. You can refer to the complete introductions of the commands in the body of the text based on the keywords
listed here.
:ACQuire:AALias
Syntax
:ACQuire:AALias <bool>
:ACQuire:AALias?
Description
Enables or disables the anti-aliasing function of the oscilloscope; or queries the on/off status of the
anti-aliasing function.
Parameter
Name Type Range Default
<bool> Bool {{1|ON}|{0|OFF}} 0|OFF
Return Format
The query returns 1 or 0.
:ACQuire:AVERages
Syntax
:ACQuire:AVERages <count>
:ACQuire:AVERages?
Description
Sets or queries the number of averages in the average acquisition mode (refer to the :ACQuire:TYPE
command).
Parameter
Name
Type
Range
Default
<count> Integer 2
n
(n indicates an integer between 1 and 13). 2
Remarks
In the average acquisition mode, the oscilloscope will acquire the waveform samples for several times, then
make an average on the waveforms, so as to lower the random noises of the input signals and increase its
vertical resolution. Greater number of averages can lower the noises and increase the vertical resolution,
but will also slow the response of the displayed waveform to the waveform changes.
Return Format
The query returns an integer.

DS4000E Programming Guide 2-5
:ACQuire:MDEPth
Syntax
:ACQuire:MDEPth <mdep>
:ACQuire:MDEPth?
Description
Sets or queries the memory depth of the oscilloscope (namely the number of waveform points that can be
stored through sampling in a single trigger). The default unit is pts (points).
Parameter
Name Type Range Default
<mdep> Discrete AUTO|7000|70000|700000|7000000 AUTO
Remarks
The formula below describes the relationship among memory depth, sample rate, and waveform length:
memory depth = sample rate x waveform length
Wherein, waveform length = horizontal time base x number of grids in the horizontal direction on the
screen. For DS4000E, the number of grids in the horizontal direction on the screen is a fixed value 14. When
<mdep> is set to "AUTO", the oscilloscope will select the memory depth automatically according to the
current sample rate and horizontal time base (refer to the :TIMebase[:MAIN]:SCALe command).
Return Format
The query returns an integer.
:ACQuire:SRATe?
Syntax
:ACQuire:SRATe?
Description
Queries the current sample rate of the oscilloscope. The default unit is Sa/s.
Return Format
The query returns the sample rate in scientific notation.
:ACQuire:TYPE
Syntax
:ACQuire:TYPE <type>
:ACQuire:TYPE?
Description
Sets or queries the data acquisition mode of the oscilloscope.
Parameter
Name Type Range Default
<type> Discrete {NORMal|AVERages|PEAK|HRESolution} NORMal
Remarks
NORMal: In this mode, the oscilloscope samples the signal at the same interval to reconstruct the
waveform. For most of the waveforms, this mode can realize the best display effects.
AVERages: In this mode, the oscilloscope will acquire the waveform samples for several times, then

RIGOL Chapter 2 Command System
2-6 DS4000E Programming Guide
make an average on the waveforms, so as to lower the random noises of the input signals and increase
its vertical resolution. You can use the :ACQuire:AVERages command to set the number of averages in
this mode.
PEAK: The oscilloscope samples the maximum and minimum value of the signal at the fixed sampling
interval to acquire the signal envelope or the narrow pulses that might be lost. This mode can avoid the
signal aliasing, but produces greater noises.
HRESolution: The oscilloscope will average the adjacent sample points of the sample waveform to
lower the random noises of the input signals and display much more smoother waveforms. If the
sample rate of the digital convertor is greater than the storage rate of the acquisition memory, this
mode is often adopted.
Return Format
The query returns NORM, AVER, PEAK, or HRES.
