SCPI Command Reference
5
Please refer to the N5980A User Guide for the complete SCPI command
reference of the N5980A. In this document there is only a very brief
summary.
The SCPI commands can be subdivided into the following command sets:
SCPI Common Commands
•
This is a common command set. It contains general housekeeping
commands. The common commands are always headed by an
asterisk. A typical example is the reset command: *RST. The
standard command set also contains query commands. Query
commands always end with a question mark.
Note: The N5980A is not fully SCPI1997 Standard compliant! Only a
subset of the required command set is supported.
SCPI Instrument Control Commands
•
The N5980A does not feature a fully standard compliant SCPI
parsers. Therefore a number of restrictions apply:
o Status handling/registers
No commands are available to query or set the status of the
instrument.
o Support of short and long form of SCPI commands
Commands may only sent in the exact format given below.
Example: :SOUR1:PATT PRBS7
You may not use: :SOURce1:PATTern PRBS7
o There are no default suffixes
You always have to add the suffix to the command
Example: :SOUR1:PATT?
You may not omit the "1" in "SOUR1".
o Multiple SCPI commands in one line
You always have to specify the full command.
SCPI standard allows: :SOUR1:PATT PRBS7;EADD ONCE
N5980A needs: :SOUR1:PATT PRBS7; :SOUR1:PATT:EADD
ONCE
The commands must always be complete, even for the
N5980A Programming Guide
