7.1 Calibration
There are two calibration systems.
●
Calibration before use
Refer to 3.1 “Calibrating Before Measurement”.
●
Calibration of equipment performance
Use an instrument with guaranteed optical wavelength and level to
assure that the MS9740B meets the performance specification. Even
though the MS9740B is operating normally, calibrate periodically at
regular intervals to maintain the performance specification. The
following two items should be calibrated by the user:
‐
Wavelength accuracy
‐
Level accuracy
The MS9740B requires calibration of performance once or twice a year.
Contact Anritsu Customer Service for periodic calibration of
performance.
