FETC2:POW:AC:DIFF? DEF,DEF,(@2),(@1) (A second FETCh? query is sent
to make a Channel B - Channel A measurement using the current
measurement data).
Example 6 - Making a Ratio Measurement
The following program segment can be carried out on the N1912A. It
queries the lower window to make a ratio measurement of Channel A/B.
The expected power level and resolution parameters are defaulted, leaving
them at their current settings. Some fine tuning of the measurement is
carried out by setting the averaging.
