A calibration unit is an integrated solution for automatic calibration of several network analyzer ports.
The unit contains calibration standards that are electronically switched when a calibration is performed. The calibration kit data for the internal standards is stored in the calibration unit, so that the analyzer can calculate the error terms and apply the calibration without any further input. Automatic calibration is generally faster and more secure than manual calibration:
There is no need to connect several standards manually. The number of standards to be connected quickly increases with the number of ports
Invalid calibrations due to operator errors (e.g. wrong standards or improper connections) are almost excluded.
No need to handle calibration kit data.
The internal standards do not wear out because they are switched electronically.
