Making High Power Measurements With Option H85
Selecting Power Ranges and Attenuator Settings
16. Select a power range that will not exceed the maximum estimated power level, but will
force the DUT into compression. For example; if your booster amplifier has a gain of
+15 dB and the DUT will compress if supplied with +15 dBm, then you would adjust
the analyzer output power not to exceed 0 dBm. This can done by setting Attenuator
Control to 10 dB by pressing Power, under Attenuator Control uncheck Auto and enter
[10] into the entry area.
17. Estimate the maximum amount of gain that could be provided by the DUT and as a
result, the maximum amount of power that could be received by Test Port 2 when the
DUT is in compression. For example; if a DUT with a maximum gain of +10 dB receives
an input of +10 dBm, then the maximum amount of power that could be received by
Test Port 2 is +20 dBm. An isolator or attenuator may be require depending on the
amount of power at Test Port 2. An isolator is place between the CPLR THRU and
SOURCE OUT for Port 2. Refer Figure 8.
