How Measurements are Calculated

Figure 1-8 details how measurements are calculated. It shows the order in
which the various power meter functions are implemented in the
measurement calculation.

The MEASure commands in this figure can be replaced with the FETCh?
and READ? commands.
Note All references to channel B in the above diagram refer to the E4417A
only. MEAS[1|2]:POW:AC? and MEAS[1|2]:POW:AC:REL? are the
only commands that apply to the E4416A.
