MEASurement Commands 2
N1911A/1912A P-Series Power Meters Programming Guide 91
Resolution
The <resolution> parameter sets the resolution of the specified window.
This parameter does not affect the resolution of the remote data but it
does affect the auto averaging setting. Where a channel is set up in both
the upper and lower window and the <resolution> parameter settings
for these windows are different, the highest resolution setting is taken to
calculate the averaging. If you are making a ratio or difference
measurement the <resolution> parameters are applied to both channels.
Source List
The <source list> parameter is used to define:
• What channels the measurements will be made on, for a dual channel
measurement.
• Whether the calculation is A- B or B- A, for a dual channel difference
measurement.
• Whether the calculation is A/B or B/A, for a ratio measurement.
Entering a <source list> is only required if you are using an N1912A.
As the N1911A has a single channel only, the source list can only be
Channel A.
The following commands are described in this chapter:
