6.Connect the Type N cable from the tracking generator output to the microwave spectrum analyzer RF INPUT. See Figure 2-86.

7.Set the microwave spectrum analyzer controls as follows:

CENTER FREQUENCY : :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: : 3.9217 GHz

SPAN ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: : 100 kHz

REFERENCE LEVEL ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: 0 dBm

RES BW : ::: :: :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: :: 1 kHz

LOG dB/DIV : : : : : : : : : : :: : : : : : : : :: :: : : : : : :: : : : :: : : : : : : : : : : : :: :: :: : : : : : :: 10 dB

8.On the microwave spectrum analyzer, press PEAK SEARCH and SIGNAL TRACK (ON), then wait for the signal to be displayed at center screen. Press

SIGNAL TRACK (OFF).

9.On the microwave spectrum analyzer, press PEAK SEARCH, PRESEL PEAK, then wait for the PEAKING! message to disappear.

10.Record the microwave spectrum analyzer marker amplitude in Table 2-79 as the LO Feedthrough Amplitude for 3.9217 GHz.

11.Repeat steps 8 through 10 for the remaining EMC analyzer CENTER FREQ and microwave spectrum analyzer CENTER FREQUENCY settings listed in Table 2-79.

12.Locate in Table 2-79 the LO Feedthrough Amplitude with the greatest amplitude 9 kHz to 1.5 GHZ, then record the amplitude as TR Entry 1 of the performance veri￿cation test record.

13.Locate in Table 2-79 the LO Feedthrough Amplitude for 2.9 GHz, then record the amplitude as TR Entry 2 of the performance veri￿cation test record.
