Functional Testing
Amplitude Accuracy at 50 MHz
4. Preset the signal source and initialize the test equipment
parameters as listed in Table 5-6, “Signal Source Initialization.”
5. Configure the equipment as shown in Figure 5-3, “Amplitude
Accuracy Test Setup.”
6. Perform the following steps for each of the nominal measured values
listed in Table 5-7, “Measurement Settings”:
a. Set the signal source amplitude to the value listed in the Nominal
Source Amplitude column in Table 5-7 .
b. On the UUT, press
Restart
and
Search.
c. Wait for the transmitter tester to finish averaging.
d. Adjust the source amplitude, as measured on the UUT, to
±0.5
dBm of the value listed in the Nominal Measured Value
column in Table 5-7 .
