6.3.1 TCXO CALIBRATION TOOL
This option allows operator/technician to adjust the output frequency
value if it varies during the operation from the predefined value. By
opening the TCXO Calibration Tool dialog box the operator/
technician first orders the AlphaWave unit to generate continuous bit
stream of all 0-s. The following frequencies are used to measure the
TCXO accuracy:
The Up/Down controls allow operator/technician to tune the TCXO
generated frequency. If the difference between the nominal and
measured value is less than Required Accuracy then the test can be
completed. To save the TCXO Control value in the Configuration Im-
age, the operator/technician must click the “Apply” button.
AWare automatically switches off the testing mode of unit, if the
TCXO Calibration dialog box is closed.
