N1911A/1912A P-Series Power Meters Programming Guide 113
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:
