Performance Verification Tests
59. Comms Absolute Power Accuracy (Options BAC or BAH)
h. Calculate the amplitude accuracy as follows:
7. Table 2-128 has two Amplitude Accuracy entries for each nominal
input amplitude setting. For each of the nominal input amplitude
setting pairs in Table 2-128, record the worst of the two Amplitude
Accuracy values in Table 2-129 and Table 2-130 as the 50 MHz
Amplitude Accuracy for the same Nominal Input Amplitude setting.
8. Copy into Table 2-129 and Table 2-130 the peak-to-peak frequency
response error for the appropriate input attenuation setting from the
Comms Frequency Response Performance Test for both the 800 MHz
