f. Conrm that the 4352B reading is approximately 20 kHz
rms
, and note the 4352B reading
as FM TEST .
g. Calculate the following formula, and record the 20 kHz range test result on the
P erformance T est Record.
T est Result (%REL) = FM TEST / FM REF * 100
11. P erform the following steps to check the 2 kHz range of the FM deviation measurement.
a. Remove the BNC cable from FM output on the AM/FM T est Source , and connect it to the
FM OUTPUT on the AM/FM T est Source as shown in Figure 2-13.

20 kHz to set the FM deviation range to 20 kHz.
c. A djust the function generator's amplitude (around -28 dBm) until the 4352B reading is 8

, and note the 4352B reading as FM REF .
d. Connect the test equipment as shown in Figure 2-14.
