Page 32: Certificate Of Calibration
If you have a measurement application that does not use all of the measurement capabilities of the network analyzer, you may ask your local Keysight Technologies service office to verify only a subset of the specifications. However, this “limited calibration” creates the possibility of making inaccurate measurements if you then use the analyzer in an application requiring additional capabilities. -
