If the successive commands belong to the same system and have one or several levels in
common, the command line can be abbreviated. To this end, the second command (after
the semicolon) is started with the level that lies below the common levels (see also Figure
1-1). The colon following the semicolon must be omitted in this case.
Example
INPut1:SHUNt EXTernal;:INPut1:GAIN 25.0
This command line is represented in its full length and contains two commands separated
from each other by the semicolon. The two commands belong to the INPut command
subsystem and have one common level.
To abbreviate the command line, the second command is started with the level below
INPut. The colon after the semicolon is omitted.
The abbreviated form of the command line reads as follows:
INPut1:SHUNt EXTernal;GAIN 25.0
However, a new command line always has to be started with the complete path.
Example
INPut1:SHUNt EXTernal
INPut1:GAIN 25.0
Responses to Queries
For each setting command, a query is defined unless explicitly specified otherwise. The
query is formed by adding a question mark to the setting command in question.
Responses to queries to the SCPI standard are partly subject to stricter rules than
responses to the IEEE 488.2 standard.
1. The requested parameter is transmitted without header.
Example
INPut:COUPling?
Response: AC
2.
Numerical values are output without a unit. Physical quantities are referred to the basic
units or to the units set with the Unit command.
Example
INPut:FILTer:LPASs:FREQuency?
Response: 3.0E5 for 300 kHz
3. Truth values (Boolean parameters) are returned as 0 (for Off) and 1 (for On).
Example
INPut:FILTer:STATe?
Response: 1
4. Text (character data) is returned in a short form.
