Calibration

The EVS300 contains a highly stable (comb) source which is used to calibrate the different signal paths in the RF frontend. The complete calibration routine takes about 8 minutes.
START Starts the internal calibration routine, the upper field displays the calibration progress. The lower table indicates the RF path and attenuator mode currently beeing calibrated. When finished the date of last calibration is updated.
CANCEL Aborts the running calibration and clears the stored calibration values, a new calibration must be completed successfully to ensure optimum accuracy.
CLEAR CAL VAL. Press to clear the stored calibration values, a new calibration must be completed successfully to ensure optimum accuracy.
