the semicolon starts with the level that lies below the common levels. The colon following
the semicolon must be omitted in this case.
Example:
SOURce:GPRF:GENerator:RFSettings:FREQuency 1GHz; :SOURce:GPRF:
GENerator:RFSettings:LEVel -80
This command line is written in its full length and contains two commands separated from
each other by the semicolon. Both commands are part of the
SOURce:GPRF:GENerator:RFSettings command subystem, i.e. they have four lev-
els in common.
When abbreviating the command line, the second command begins with the level below
SOURce:GPRF:GENerator:RFSettings. The colon after the semicolon is omitted.
The abbreviated form of the command line reads as follows:
SOURce:GPRF:GENerator:RFSettings:FREQuency 1GHz;LEVel -80
A new command line must always begin with the complete path.
Example:
SOURce:GPRF:GENerator:RFSettings:FREQuency 1GHz
SOURce:GPRF:GENerator:RFSettings:LEVel -80
5.2.4.4 Responses to Queries
A query is defined for each setting command unless explicitly specified otherwise. It is
formed by adding a question mark to the associated setting command. The following rules
apply to the responses:
●
The requested parameter is transmitted without header.
Example: ROUTe:GPRF:GENerator:SCENario:SALone?
Response: RF1C
●
Maximum values, minimum values and all further quantities which are requested via
a special text parameter are returned as numerical values.
Example: SOURce:GPRF:GENerator:RFSettings:FREQuency? MAX
Response: 6.000000E+009
●
Numerical values are returned without their unit. The default unit for each command
is reported in the command reference description.
Example: SOURce:GPRF:GENerator:RFSettings:FREQuency? MAX
Response: 6.000000E+009 for 6 GHz
●
Boolean values are returned as 0 (for OFF/FALSE) and 1 (for ON/TRUE). Possible
exceptions to this rule are reported in the command reference description.
Example: SENSe:BASE:REFerence:FREQuency:LOCKed?
Response: 1
●
Text (character data) is returned in short form (see also next section).
Example: SOURce:GPRF:GENerator:BBMode?
Response: DTON (for DTONe, dual tone)
