SCPI command programming notes
This section contains general information about using Standard Commands for Programmable
Instruments (SCPI).
SCPI command formatting
This section describes the formatting that this manual uses when discussing SCPI commands.
SCPI command short and long forms
This documentation shows SCPI commands with both uppercase and lowercase letters. The
uppercase letters are the required elements of a command. The lowercase letters are optional.
However, if you choose to include the letters that are shown in lowercase letters, you must include all
of them.
When you send a command to the instrument, letter case is not important — you can mix uppercase
and lowercase letters in program messages.
For example, you can send the command SENSe:COUNt? in any of the following formats:
SENSe:COUNt?
sense:count?
SENS:COUN?
Sens:Coun?
Optional command words
If a command word is enclosed in brackets ([ ]), the command word is optional. Do not include the
br
ackets if you send the optional command word to the instrument.
For example, you can send the command :SYSTem:BEEPer[:IMMediate] <n1>, <n2> in any of
the following formats:
:SYSTem:BEEPer:IMMediate 500, 1
:SYSTem:BEEPer 500, 1
:SYST:BEEP:IMMediate 500, 1
:SYST:BEEP 500, 1
MINimum, MAXimum, and DEFault
You can use MINimum, MAXimum, or DEFault instead of a parameter for some commands.
For example, you can set the parameter for the command [:SENSe[1]]:RESistance:NPLCycles
to the minimum, maximum, or default value. To set NPLC to the minimum value, you can send either
of these commands:
:SENSe1:RESistance:NPLCycles MINimum
:SENS:RES:NPLC MIN
