1. Programming Overview

This chapter introduces how to build communication between the instrument and the PC. It also introduces how to configure a system for remote instrument control. By using USB and LAN interfaces, in combination with NI-VISA and programming languages, users can remotely control the instruments. Through LAN interface, VXI-11, Sockets and Telnet protocols can be used to communicate with the instruments.

1.1 Establishing Communications

1.1.1 Install NI-VISA

Before programming, you need to install the 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 which is a user interface to control and test remotely connected devices. The Run-Time Engine is recommended, as it is a much smaller download than the full version and includes the necessary tools for basic communication to instruments.

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, follow these steps to install NI-VISA (The full version of NI-VISA 5.4 is used in this example. Newer versions are likely, and should be compatible with SIGLENT instrumentation. Download the latest version available for the operating system being used by the controlling computer):

a. Double click the visa540_full.exe, dialog shown as below:

SDL1000X Programming Guide 1

SIGLENT

b. Click Unzip, the installation process will automatically launch after unzipping files. If your computer needs to install .NET Framework 4, it may auto start.

c. The NI-VISA installing dialog is shown above. Click Next to start the installation process.

d. Set the install path, default path is “C:\Program Files\National Instruments\”, you can change it. Click Next, dialog shown as above.

SDL1000X Programming Guide 2

SIGLENT

e. Click Next twice, in the License Agreement dialog, select the “I accept the above 2 License Agreement(s).”,and click Next, dialog shown as below:

f. Click Next to begin installation.

g. Now the installation is complete. Reboot your PC.

1.1.2 Connect the Instrument

Depending on the specific model, your electronic load may be able to communicate with a PC through the USB or LAN interface.

Connect the instrument and the USB Host interface of the PC using a USB

SDL1000X Programming Guide 3

SIGLENT

cable. Assuming your PC is already turned on, turn on your electronic load, and then the PC will display the “Device Setup”screen as it automatically installs the device driver as shown below. Wait for the installation to complete and then proceed to the next step.

1.2 Remote Control

1.2.1 User-defined Programming

Users can use SCPI commands via a computer to program and control the electronic load. For details, refer to the introductions in "Programming Examples".

1.2.2 Send SCPI Commands via NI_MAX

NI-Measurement and Automation eXplorer (NI-MAX) is a program created and maintained by National Instruments. It provides a basic remote control interface for VXI, LAN, USB, GPIB, and Serial communications. It is a utility that enables you to send commands one-at-a-time and also retrieve data from connected devices. It is a great tool for troubleshooting and testing command sequences. The oscilloscopes can be controlled remotely by sending SCPI commands via NI-MAX.

2. SCPI Overview

2.1 Command Format

SCPI commands present a hierarchical tree structure containing multiple subsystems, each of the subsystems is made up of a root keyword and several subkeywords. The command string usually starts with “:”, the keywords are

separated by “:” and the followed parameter settings are separated by space.

Query commands add “?” at the end of the string.

For example: :SENSe:FREQuency:CENTer <freq> :SENSe:FREQuency:CENTer? SENSe is the root key of the command, FREQuency and CENTer are second

and third keywords. The command begins with “:”, and separates the keywords

at the same time, <freq> separated by space and represents the parameter available for setting; “?” represents a query.

SDL1000X Programming Guide 4

SIGLENT

2.2 Symbol Instruction

The following four symbols are not the content of SCPI commands and can not be sent with the commands, but are usually used in the commands.

1、Triangle Brackets < > The parameter in the triangle brackets can be ignored.When parameter is ignored, the instrument will set parameter to its default. For example: In the“[:SOURce]:BATTery:LEVel <value>”command in“:SOURce:BATTery: LEVel 4”.

2、Braces { } The parameters in the braces are optional which can be ignored or set for one or more times. For example: The “{ON | OFF | 0 | 1}”parameter in “[:SOURce]:INPut[:STATe] {ON | OFF | 0 | 1}”command.

3、Vertical Bar | The vertical bar is used to separate multiple parameters and when sendi ng the command,you can choose one of the parameters. For example, i n the “[:SOURce]:INPut[:STATe] {ON | OFF | 0 | 1}” command, the par ameters availiable are“OFF”、“ON”、“0”or“1”；such as “:SOURce:I NPut:STATe ON” or “:SOURce:INPut:STATe 0”.

4、Square Brackets [ ] The content in the square brackets can be ignored. When the parameter is ignored, the instrument will set the parameter to its default. For exmple, In the “[:SOURce]:INPut[:STATe]?” command, sending any of the four commands below can generate the same effect: :INPut? :INPut:STATe? :SOURce:INPut? :SOURce:INPut:STATe?

2.3 Parameter Type

The parameters in the commands introduced in this manual include 5 types: boolean, enumeration, integer, float, specific format.

SDL1000X Programming Guide 5

SIGLENT

1、Boolean

The parameters in the commands could be “OFF”, “ON”, “0” or “1”. For example: [:SOURce]:SHORt[:STATe] {ON | OFF | 0 | 1}

2、Enumeration The parameter could be any of the values listed. For example: [:SOURce]:FUNCtion {CURRent | VOLTage | POWer | RESistance | LED} The parameter is “CURRent”、“VOLTage”、“POWer”、“RESistance”、“LED”

3、Integer

All parameters expressed by <number> and <step> are integer. It can be any integer within the effective value range. Notes: The command is invalid if the parameter value beyond the scope. The parameter will be rounded to integer when it is decimal. For example: [:SOURce]:LIST:LEVel? <step> The parameter <step> can be set to any integer in effective range. It wil l be rounded to 3 when it is set to 3.988.

4、Float

All parameters expressed by <value> are float. It can be any float within the effective value range. Notes: The command is invalid if the parameter value beyond the scope. The parameter is also regarded as float when it is integer. For example: [:SOURce]:CURRent:IRANGe < value > The parameter < value > can be set to any real number between 0 and 30.

5、Specific format type

The parameter should be input in specific format and with specified symbol. For example: LAN:IPADdress <aaa.bbb.ccc.ddd> The parameter is separated by “.”. It is also take effect when lack numeric characters. The parameter will be set in progressive type. For example, if the oringnal IP address is “12.13.14.2”, IP address will be set to “15.6.0.2” when the parameter is “15.6.0”.

2.4 Command Abbreviation

All of the commands are not case sensitive, so you can use any of them. But if abbreviation is used, all the capital letters in the command must be

SDL1000X Programming Guide 6

SIGLENT

written completely. For example: :SOURce:CURRent:SLEW:POSitive? Can be abbreviated to： :SOUR:CURR:SLEW:POS?

2.5 Special instructions

1、 When sets the current range，if <value> is greater than 5, the current range

will be set to 30A; if <value> is less than 5, the current range will be set to 5A.

2、 When sets the voltage range，if <value> is greater than 36, the voltage

range will be set to 150V; if <value> is less than 36, the voltage range will be set to 36V.

3、 The parameters is {<value> | MINimum | MAXimum | DEFault}

enumerations. Its meanings are as follows

<value> ：Any setting value MINimum ：The minimum value in the setting range MAXimum ：The maximum value in the setting range DEFault ：The default value for the setting value

4.1 Examples of Using VISA

4.1.1 Example of VC++

Environment: Win7 32bit system, Visual Studio The functions of this example: use the NI-VISA, to control the device with

USBTMC or TCP/IP access to do a write and read. Follow the steps to finish the example: 1、 Open Visual Studio, create a new VC++ win32 console project. 2、 Set the project environment to use the NI-VISA lib, there are two ways to

use NI-VISA, static or automatic: (1) Static: find files: visa.h, visatype.h, visa32.lib in NI-VISA install path. Copy

them to your project, and add them into project. In the projectname.cpp file, add the follow two lines:

#include "visa.h"

#pragma comment (lib,"visa32.lib") (2) Automatic: Set the .h file include directory, the NI-VISA install path, in our computer we set

the path is: C:\Program Files\IVI Foundation \VISA\WinNT\include. Set this path to project---properties---c/c++---General---Additional Include Directories: See the picture.

column. 3、 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. 4、 Connect them as shown in the figure below

5、Select the device resource from the VISA Resource Name list box and run the program.

In this example, the VI opens a VISA session to a USBTMC device, writes a command to the device, and reads back the response. In this example, the specific command being sent is the device ID query. Check with your device manufacturer for the device command set. After all communication is complete, the VI closes the VISA session.

6、Communicating with the device via TCP/IP is similar to USBTMC. But you

need to change VISA Write and VISA Read Function to Synchronous I/O. The LabVIEW default is asynchronous I/O. Right-click the node and select Synchronous I/O Mod>>Synchronous from the shortcut menu to write or read data synchronously.

7、 Connect them as shown in the figure below

8、 Input the IP address and run the program.
