Eliminating Unwanted Mixing and Leakage Signals

By placing filters between the mixer's IF port and the receiver's input port, you can
eliminate unwanted mixing and leakage signals from entering the analyzer's receiver.
Filtering is required in both fixed and broadband measurements. Therefore, when
configuring broad-band (swept) measurements, you may need to trade some measurement
bandwidth for the ability to more selectively filter signals entering the analyzer receiver.
