N1911A/1912A P-Series Power Meters Programming Guide 19
Example 2 - Specifying the Source List Parameter
The  CONFigure and READ? commands have three optional parameters, an 
expected power value, a resolution and a source list. These parameters 
must be entered in the specified order. If parameters are omitted, they 
default from the right. The parameter DEFault is used as a place holder.
The following examples use the source list parameter to specify the 
measurement channel as Channel A. The expected power and resolution 
parameters are defaulted, leaving them at their current settings. The 
measurement is carried out on the upper window.
Although the READ? and FETCh? queries have three optional parameters it 
is not necessary to define them as shown in these examples. If they are 
defined they must be identical to those defined in the CONFigure 
command otherwise an error occurs.
Using READ?
FETC2? Retrieves the lower window’s measurement
For the N1911A it is not necessary to specify a channel as only one channel is available.
ABOR1 Aborts Channel A
CONF1 DEF,DEF,(@1) Configures the upper window to make a 
Channel A measurement using the current 
expected power and resolution settings
READ1? Takes the upper window’s measurement
