7.1 Calibration Requirements
Calibration is done to help maintain the MT8801C’s performance.
Calibration should be performed periodically even if the MT8801C is operating nor-
mally.
We recommend that the MT8801C be calibrated once or twice a year.
Contact the Service Department of Anritsu Corporation if the MT8801C fails to meet
the specifications during calibration.
