Functional Testing
Amplitude Accuracy at 50 MHz
e. Record the signal amplitude, as measured by the power meter, in
the Amplitude Input
i
column of Table 5-8, “Amplitude Accuracy
at 50 MHz Report.”
f. Press
Restart
.
g. Wait for the transmitter tester to finish averaging, and read the
marker value.
h. Record the signal amplitude, as measured by the UUT, in the
Measured Amplitude X
i
column of Table 5-8 .
i. Calculate the amplitude accuracy using the following equation
and record in the Error Amp_Acc
i
column of Table 5-8 :
