Increasing Network Analyzer Dynamic Range; To Increase The Receiver Input Power - HP 8712C User Manual

You should maximize the receiver input power to achieve the highest dynamic
range. You can increase the analyzer's source output power so that the test
device output power is within the measurement range of the analyzer.
Press @GEE]
If your test device output power stays within the maximum input limits
shown below, the receiver compression will be minimized.
Remember to not exceed the receiver input damage limit of +23 dJ3m.

Increasing Network Analyzer Dynamic Range

Receiver dynamic range is the difference between the analyzer's maximum
allowable input level and its noise floor. For a measurement to be valid, input
signals must be within these boundaries. The dynamic range is affected by
two factors:
input power to the device under test (DUT)
l
Maximum Recommended Input Power levels
N O T E
The normalization power level may affect the analyzer's dynamic accuracy. See Figure 10-l in
Chapter 10.
and enter the new source power level.
