1 Power Meter Remote Operation
Example 5 - Making a Difference Measurement
The following command is performed on the N1912A. It queries the lower window
to make a difference measurement of Channel B -Channel A. The expected power
and resolution parameters are defaulted, leaving them at their current settings.
Example 6 - Making a Ratio Measurement
The following command is performed on the N1912A. It queries the upper window
to make a ratio measurement of Channel A/B. The expected power and resolution
parameters are defaulted, leaving them at their current settings.
Keysight N1912A Only
NOTE
The operation of the MEASure? command when the source list parameter is
defaulted depends on the current setup of the window concerned (for example,
A, B, A/B, A-B etc.) and on the particular command used (for example,
MEAS[:POW][:AC]? and MEAS:POW:AC:RAT?).
This means that when the source list parameter is defaulted, there are a number
of possibilities.
