SECTION 7 PERFORMANCE TEST
7-3
7.3 Performance Test
To confirm performance after the MG3641A/MG3642A acceptance test, periodical inspection, or repair, check the
following items for performance test:
• Output frequency
• Output level frequency characteristics
• Output level accuracy
• FM deviation, FM distortion
• AM modulation factor, AM distortion
The performance test is executed according to the ordinary use state; therefore, the user need not adjust the inside of
the device like the calibration. For important items, the performance test should be performed periodically for preventive
maintenance.
Use the performance test result sheet in Appendix E to record the test results.
CAUTION
For performance test, the tested unit and measuring instruments must sufficiently be preheated for at least 30
minutes to make them stable. To obtain the highest measurement accuracy, the performance test must be
executed at room temperature or lower; the AC power voltage varies a little only; there must be no abnormal
noise, vibration, dust, or humidity.
