Power Meter Remote Operation
Making Measurements
Example 6 - Making a Ratio Measurement
The following command can only be carried out on the E4417A. 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.
Note E4417A only.
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.
Command
MEAS1[:POW][AC]?
MEAS2[:POW][AC]?
MEAS1:POW:AC:RAT
