53. IF INPUT Accuracy (Option AYZ only)
18.Subtract the Input Power (step 14) from the Measured Power
(step 17) and record the difference as the IF INPUT Accuracy.
IF INPUT Accuracy = Measured Power – Input Power
For example, if the Measured Power is –29.34 dBm and the Input
Power is –30.08 dBm, the IF INPUT Accuracy would be 0.74 dB.
19.Record the IF INPUT Accuracy as Test Record entry 1 in the
Performance Verification Test Record.
