The purpose of this section is to show how receiver calibrations can be set up, and how some of the additional receiver calibration utilities can be used.
Unlike conventional VNA RF calibrations (like SOLT, LRL/LRM, and others) that are used to calibrate the VNA for S-parameter measurements, the receiver calibration is more of an absolute power calibration to help with measurements such as:
• Harmonics
• IMD and IP3, and other multi-tone distortion measurements
• Mixer conversion loss (in the simpler scalar cases)
• Noise figure measurements
• Other times when the VNA is just used as a channelized receiver
