Special Attention：
Red "CAL 0" marked on the product means using the system calibration
parameters，that is the calibrated port is just at the RF port of the product.
"CAL 1" means using the user calibration data.
If using adapter, in the case of low frequency, there is no need to do
calibration.

First, there is necessary to explain the distinction between correction and
calibration. For those who have used the vector network must know that
accurate measuring of the RF impedance of the DUT requires the
calibration of the test cable, but they may not know clearly about
correction.
Calibration means after connecting the test cable with the device, use
calibration kit to calibrate the cable and then keep the calibrating results
(ie. Calibration meters) ,which if used to correct the measurement results
as using the test cable to test the measured object, the measurement
result is corrected, and vice versa. In other words, correction means
whether or not use calibration parameters to correct the measurement
result when testing the measured object.
Hold down the CTRL key and press the M key at System Information
Interface, you will switch to the Correction and Calibration interface.
