Programming Guide 1 Programming Overview By using USB and LAN interfaces, in combination with NI-VISA and programming languages, users can remotely control the waveform generator. Through LAN interface, VXI-11, Sockets and Telnet protocols can be used to communicate with the instruments. 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. Build communication via VISA 1.1.1 Install NI-VISA Before programming, please make sure that you have properly installed the latest version of...

Programming Guide 1.1.2 Connect the instrument Depending on the specific model, the arbitrary waveform generator may be able to communicate with a PC through the USB or LAN interface. Connect the arbitrary waveform generator and the USB Host interface of the PC using a USB cable. Assuming your PC is already turned on, turn on the SDG, 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.

Programming Guide Remote Control 1.2.1 User-defined Programming Users can send SCPI commands via a computer to program and control the arbitrary waveform generator. For details, refer to the introductions in " Programming Examples". 1.2.2 Using SCPI via NI-MAX 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. The SDG can be controlled remotely by sending SCPI commands via NI-MAX. 1.2.3 Using SCPI over Telnet Telnet provides a means of communicating with the SDG over the LAN....

Programming Guide 4. At the Telnet command line, type: open XXX.XXX.XXX.XXX 5024 Where XXX.XXX.XXX.XXX is the instrument’s IP address and 5024 is the port. You should see a response similar to the following: 5. At the SCPI> prompt, input the SCPI commands such as *IDN? to return the company name, model number, serial number, and firmware version number.

SIGUENT Programming Guide 6. To exit the SCPI> session, press the Ctrl+] keys simultaneously. 7. Type quit at the prompt or close the Telnet window to close the connection to the instrument and exit Telnet. 1.2.4 Using SCPI over Socket Socket API can be used to control the SDG series by LAN without installing any other libraries. This can reduce the complexity of programming. SOCKET ADDRESS IP address + port number IP ADDRESS SDG IP address Please see section 4.2 "Examples of Using Sockets" for the details.

Programming Guide 2 Introduction to the SCPI Language 2.1 About Commands & Queries This section lists and describes the remote control commands and queries recognized by the instrument. All commands and queries can be executed in either local or remote state. Each command or query, with syntax and other information, has some examples listed. The commands are given in both long and short format at “COMMAND SYNTAX”and “QUERY SYNTAX”, 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 (?)...

SIGUENT Programming Guide 3 Commands and Queries 3.1 IEEE 488.2 Common Command Introduction The IEEE standard defines the common commands used for querying the basic information of the instrument or executing basic operations. These commands usually start with "*" and the length of the keywords of the command is usually 3 characters. 3.1.1 *IDN DESCRIPTION The *IDN? query causes the instrument to identify itself. The response is comprised of the manufacturer, model, serial number and firmware version. QUERY SYNTAX *IDN? RESPONSE FORMAT Format 1: *IDN, <device id>,<model>,<serial...
