TEST PROCEDURES
Fig. 5-1-14 SSB phase noise test set-up
(1)
Connect the test equipment as shown in Fig. 5-1-14.
(2)
Set the UUT to
[Carrier Freq.]
470 MHz
[RF Level]
7 dBm, modulation to OFF.
(3)
Using the phase noise measuring device, measure SSB phase noise at a 20 kHz
offset which should be less than
−
116 dBc.
