Optimizing Measurements
Increasing Network Analyzer Dynamic Range
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)
• receiver noise floor
To Increase the Receiver Input Power
You should maximize the receiver input power to achieve the highest
dynamic range. You can increase the analyzer's source output power as
long as the test device output power stays within the measurement
range of the analyzer.
Press and enter the new source power level.
If your test device output power stays within the maximum input limits
shown below, the receiver compression will be minimized.
Maximum Recommended Input Power Levels
CAUTION Remember to not exceed the receiver input damage limit of +26 dBm.
NOTE The normalization power level may affect the analyzer's dynamic
accuracy. Refer to Chapter 9, “Specifications. ”
