Fops Settings - Agilent Technologies N9913A User Manual

Overview
The following shows a typical use case for FOPS:
 The DUT is a long section of cable with a mixer and bandpass filter on the IF
 The FieldFox source is tuned to f1.
 The USB power sensor, with an equally long USB/LAN cable, is connected to
 Conversion gain/loss is measured at f2, which is (f1 +/- f Offset).
NOTE The dynamic range with FOPS may be significantly different when using various
power sensors. In general, the lower frequency range sensors have better
dynamic range.
