4. Test Port Output Power Linearity

This test verifies the analyzer's test port output power linearity throughout the analyzer's
frequency range. A power meter calibration is used to set the reference output power
across the frequency range of the analyzer. The analyzer's B-channel receiver is used to
determine power linearity after each change in output power.
This test does not verify the functionality of the step attenuator. To verify its
