(4) Test procedure
STEP PROCEDURE
1. Adjust the power meter to the zero point and correct the sensor sensitivity.
2. Set the MG3641A/MG3642A output level to 0 dBm.
3. Set the MG3641A/MG3642A to the frequency to be measured.
4. Set the calibration factor of the sensor of the power meter and read the output level.
5. Repeat steps 3 and 4.
(5) Note on test
The MG3641A/MG3642A output level is defined with the RF output connector. To measure the output level,
directly connect the power sensor to the MG3641A/MG3642A RF output connector.
