Standard Commands

Language

The instrument command language is Standard Commands for Programmable Instruments (SCPI).

The programming examples and information in this chapter use the SCPI format. SCPI follows IEEE 488.2-1987 Codes, Formats, Protocols and Common Commands. Commands are sent over an GPIB bus which follows IEEE 488.1.

If you are already familiar with Standard Commands for Programmable Instruments (SCPI) programming techniques, go to the section “Example Speed Calculation” on page 4-74for switching speed information. The alphabetical listing of commands and command tree can be used for your own applications.

The programming examples in this manual are written in HP BASIC 5.0 for GPIB.

HP BASIC handles some of the redundant miscellaneous overhead associated with IEEE Standard 488.1 (GPIB). For instance, when a BASIC OUTPUT statement is used (by the active controller) to send data to an GPIB device, a sequence of commands and data are sent over the bus. The HP BASIC OUTPUT statement causes more than just the output of data to take place.

OUTPUT 709 “Data”

1.The unlisten command is sent.

2.The talker’s address command is sent (the address of the computer).

3.The listener’s address command (09) is sent.

4.The data bytes “D”, “a”, “t”, and “a” are sent.

5.Terminators CR and LF are sent.

All bytes are sent using the GPIB’s interlocking handshake to ensure that the listener has received each byte.

For controllers that are using a programming language other than

HP BASIC, additional steps may have to be added to the program examples given in this manual. For more information, refer to IEEE Standard 488.1 (GPIB) and IEEE Standard 488.2-1987 Codes, Formats, Protocols and Common Commands.
