2.2.13 Calibration
Calibrations are required to take measurements within the specifications of the analyzer.
CAUTION:
1.
Wait 60 minutes after turning the power on before performing the calibrations.
2.
If a calibration is performed during the first 10 minutes after the power is turned on, spectrum analyzers with
OPT 23 installed may occasionally display error messages since the reference frequency source is not stable.
There are three methods to calibrate the analyzer as shown below.
•
Cal All
Performs calibrations for all items to see if they meet the specifications.
Perform them before taking measurements. Processing time: Approximately 9 minutes.
•
Total Gain
Performs calibrations with more accuracy than Cal All, because user-defined measurement conditions
are used. Set the conditions first before the calibrations. Processing time: Approximately 1 minute.
•
Cal Each Item
Performs calibration on only one item.
