5.2.3 Structure of a Command Line
Several commands in a line are separated by a semicolon ";". If the next command belongs to a
different command system, the semicolon is followed by a colon.
Example:
SENSe:FREQuency:STARt MINimum;:OUTPut:FILTer:LPAS:STATe ON
This command line contains two commands. The first command is part of the SENSe
system and is used to specify the start frequency of a scan. The second command is part
of the OUTPut system and sets the AF filter.
If the successive commands belong to the same system, having one or several levels in common, the
command line can be abbreviated. To this end, the second command after the semicolon starts with the
level that lies below the common levels (see also Figure 5-1). The colon following the semicolon must
be omitted in this case.
Example:
SENSe:FREQuency:MODE CW;:SENSe:FREQuency:FIXed:AFC ON
This command line is represented in its full length and contains two commands separated
from each other by the semicolon. Both commands are part of the SOURce command
system, subsystem FREQuency, i.e. they have two common levels.
When abbreviating the command line, the second command begins with the level below
SENSe:FREQuency. The colon after the semicolon is omitted.
The abbreviated form of the command line reads as follows:
SENSe:FREQuency:MODE CW;FIXed:AFC ON
However, a new command line always begins with the complete path.
Example: SENSe:FREQuency:MODE CW
SENSe:FREQuency:FIXed:AFC ON
