Maintaining Test Port Output Power During Sweep Retrace - Agilent Technologies 8719D User Manual

Maintaining 'Ikst Port Output Power During Sweep Retrace
During standard operation, the analyzer provides output power during its forward frequency
sweep, but may provide output power during its sweep retrace. If the device under
not
test (such as an amplifier with AGC circuitry) requires constant power, then you can set the
analyzer to maintain test port output power during its sweep retrace.
The analyzer now maintains test port output power during sweep retrace.
On the HP 87221) only, retrace power will be lost at the point when the sweep
crosses the frequency boundary of 20 GHz.
The frequency sweep of the network analyzer is such that when it reaches
2.55 GHz, it momentarily jumps to 6.35 GHz before returning to 2.55 GHz and
continuing the rest of the sweep.
This discontinuity in the frequency sweep may be of concern to those making
measurements of frequency sensitive amplifiers having AGC circuitry.
