36. Set the step attenuator to 0
dB.
38. Write the mean value (which appears on the analyzer’s display) in the “Test
Port Measurement”
colrmm
of the “Performance Test Record.” This column
is also labeled “G.”
39. Repeat steps 36 through 38 for each setting of the step attenuator.
40. Calculate dynamic accuracy for each step by using the formula

FI.
Place these values in the appropriate column of the “Performance Test

In
Case
of Difkulty
1. If the analyzer fails the test at ALL power levels, be sure you followed the
recommended attenuator settings as listed in the “Performance Test Record.”
Repeat this performance test.
2. If both test port measured values are out of specifications:
a. Recalibrate the power meter.
b. Repeat this performance test.
