Programming Overview
This chapter introduces how to execute remote communications
between a SIGLENT digital oscilloscope and the computer. It also
introduces how to establish a remote control link over a
communication bus.
Build communication
Install NI-VISA
Before programming, you need to install National
Instruments NI-VISA library, which you can download from the
National Instruments web-site. Currently, NI-VISA is packaged
in two versions: a full version and a Run-Time Engine version.
The full version includes the NI device drivers and a tool named
NI MAX that is a user interface to control the device. The RunTime Engine is much smaller than the full version and only
includes NI device driver.
For example, you can get the NI-VISA 5.4 full version from:
http://www.ni.com/download/ni-visa-5.4/4230/en/.
You also can download NI-VISA Run-Time Engine 5.4 to
your PC and install it as the default selection. Its installation
process is similar with the full version.
After you downloaded the file you can follow the steps
below to install it:

Digital Oscilloscopes Series
Connect the instrument
Depending on your specific model your oscilloscope may be able to
communicate with a PC through the USB or LAN interface. This
manual takes the USB as an example. (For instructions to
communicate with a PC through the LAN interface see the User
Manual.)
a.Connect the USB Device interface at the rear panel of the
oscilloscope and the USB Host interface of the PC using a USB
cable. Assuming your PC is already turned on, turn on your
oscilloscope and your PC will display the ―Device Setup‖ screen
as it automatically installs the device driver as shown below.
b. Wait for the installation to complete and then proceed to the
next step.

How To Remote Control
a. User-defined Programming
Users can use SCPI commands to program and control the
digital oscilloscope. For details, refer to the introductions in
"Programming Examples".
b .Send SCPI Commands via NI-VISA
You can control the oscilloscope remotely by sending SCPI
commands via NI-VISA software.

About these Commands & Queries
This section lists describes the remote control commands and
queries recognized by the instrument. All commands and queries can
be executed in either local or remote state.
The description for each command or query, with syntax and other
information, begins on a new page. The name (header) is given in
both long and short form at the top of the page, and the subject is
indicated as a command or query or both. Queries perform actions
such as obtaining information, and are recognized by the question
mark (?) following the header.
How are they listed?
The descriptions are listed in alphabetical order according to their
long form. Thus the description of ATTENUATION, whose short
form is ATTN, is listed before that of AUTO SETUP, whose short
form is ASET.
How are they described?
In the descriptions themselves, a brief explanation of the function
performed is given. This is followed by a presentation of the formal
syntax, with the header given in Upper-and-Lower-Case characters
and the short form derived from it in ALL UPPER-CASE characters.
Where applicable, the syntax of the query is given with the format of
its response.
Where can they be used?
The commands and queries listed here can be used for all Siglent‘s
Digital Oscilloscope Series digital instruments.

Applicable to the following models
SDS1000CML/CML+
SDS1000DL/DL+
SDS1000CNL/CNL+
SDS1000/1000X/1000X-S/1000X+/1000X-E
SDS2000/SDS2000X
SPO models
SDS1000X/1000X+/SDS1000X-E
SDS2000/2000X
Certain commands are only applicable to SPO oscilloscopes models
and are described accordingly.
SPO oscilloscopes models are in the table below.
What is an SPO model?
SPO model uses Siglent-innovated waveform acquisition and
graphics processing engine which supports high capture rate, multi-
level intensity grading and color temperature display, with deep
memory storage and the use of new digital trigger technology
supports rich trigger types and precise trigger. All of these
technologies are collectively known as SPO (Super Phosphor
Oscilloscope) technology.

Command Notation
The following notation is used in the commands:
< > Angular brackets enclose words that are used as placeholders,
of which there are two types: the header path and the data
parameter of a command.
: = A colon followed by an equals sign separates a placeholder
from the description of the type and range of values that may
be used in a command instead of the placeholder.
{} Braces enclose a list of choices, one of which one must be
made.
[ ] Square brackets enclose optional items.
… An ellipsis indicates that the items both to its left and right
may be repeated a number of times.
As an example, consider the syntax notation for the command to set
the vertical input sensitivity:
<channel>:VOLT_DIV <v_gain>
<channel> : = {C1, C2, C3, C4}
<v_gain>: = 2 mV to 10 V
The first line shows the formal appearance of the command, with
<channel> denoting the placeholder for the header path and
<v_gain> the placeholder for the data parameter specifying the
desired vertical gain value. The second line indicates that one of four
channels must be chosen for the header path. And the third explains
that the actual vertical gain can be set to any value between 2 mV
and 10 V.

DESCRIPTION
The COMM_HEADER command controls the
way the oscilloscope formats responses to
queries. There are three response formats:
LONG, in which responses start with the long
form of the header word; SHORT, where
responses start with the short form of the
header word; and OFF, for which headers are
omitted from the response and units in
numbers are suppressed.
Unless you request otherwise, the SHORT
response format is used.
This command does not affect the
interpretation of messages sent to the
oscilloscope. Headers can be sent in their long
or short form regardless of the
COMM_HEADER setting.
Querying the vertical sensitivity of Channel 1
may result in one of the following responses:

(1) The Power On (PON) bit is always turned on (1) when the unit is powered up.
(2) The User Request (URQ) bit is set true (1) when a soft key is pressed. An associated register
URR identifies which key was selected. For further details refer to the URR? query.
(3) The CoMmand parser Error bit (CME) is set true (1) whenever a command syntax error is
detected. The CME bit has an associated CoMmand parser Register (CMR) which specifies
the error code. Refer to the query CMR? for further details.
(4) The EXecution Error bit (EXE) is set true (1) when a command cannot be executed due to
some device condition (e.g. oscilloscope in local state) or a semantic error. The EXE bit has
an associated Execution Error Register (EXR) which specifies the error code. Refer to query
EXR? for further details.
(5) The Device specific Error (DDE) is set true (1) whenever a hardware failure has occurred at
power-up, or execution time, such as a channel overload condition, a trigger or a timebase
circuit defect. The origin of the failure may be localized via the DDR? or the self test *TST?
query.
(6) The Query Error bit (QYE) is set true (1) whenever (a) an attempt is made to read data from
the Output Queue when no output is either present or pending, (b) data in the Output Queue
has been lost, (c) both output and input buffers are full (deadlock state), (d) an attempt is
made by the controller to read before having sent an <END>, (e) a command is received
before the response to the previous query was read (output buffer flushed).
(7) The ReQuest Control bit (RQC) is always false (0), as the oscilloscope has no GPIB
controlling capability.
(8) The OPeration Complete bit (OPC) is set true (1) whenever *OPC has been received, since
commands and queries are strictly executed in sequential order. The oscilloscope starts
processing a command only when the previous command has been entirely executed.

vertical sensitivity of the math waveform of the
specified source. We can only set the value of
existing math waveforms.
The FFT waveform isn‘t included.
The response to the MATH_VERT_DIV? query
indicates the specified scale of math waveform of
specified source.
The PHA is phase, the others are the same as
the specified type of the instrument‘s delay
measure.
QUERY SYNTAX
<source>:MEAsure_Delay? <type>
RESPONSE FORMAT
<source>:MEAD <type>,<value>
EXAMPLE
The following instruction sets the type of delay
measure to phase between C1 and C2.
Command message:
MEAD PHA,C1-C2

CHANNEL
OFFSET, OFST
Command/Query
DESCRIPTION
The OFFSET command allows adjustment of the
vertical offset of the specified input channel. The
maximum ranges depend on the fixed sensitivity
setting.
If an out-of-range value is entered, the oscilloscope
is set to the closest possible value and the VAB bit
(bit 2) in the STB register is set.
The OFFSET? query returns the offset value of the
specified channel.
COMMAND SYNTAX
<channel>: OFfSeT <offset>
<channel>: = {C1, C2, C3,C4}
<offset>: = See the oscilloscope‘s specifications.
QUERY SYNTAX
<channel>: OFfSeT?
RESPONSE FORMAT
<channel>: OFfSeT <offset>
EXAMPLE
The following command sets the offset of Channel
2 to -3 V:
Command message:
C2:OFST -3V

STATUS
*OPC
Command/Query
DESCRIPTION
The *OPC (OPeration Complete) command sets to
true the OPC bit (bit 0) in the standard Event Status
Register (ESR). This command has no other effect
on the operation of the oscilloscope because the
instrument starts parsing a command or query only
after it has completely processed the previous
command or query.
The *OPC? query always responds with the ASCII
character ―1‖ because the oscilloscope only
responds to the query when the previous command
has been entirely executed.
