77 SNA5000A Vector Network Analyzer User Manual
3.5 Receiver calibration
The vector network analyzer receiver power has been factory calibrated, but the factory
calibration may not guarantee sufficient accuracy in every situation. The user can conduct a
receiver power calibration before the test to improve the test accuracy. To ensure the
calibration accuracy of the receiver, it is better to calibrate the power of the internal source
before the calibration of the receiver.
