6. Measure the Half IF signal level as follows:
a. Set the RF signal generator to the frequency in the Center frequencies and
signal generator frequencies for Half-IF table. (See Table 82.)
b. Set the RSA5100B Center Frequency to the frequency in the Center
frequencies and signal generator frequencies for Half-IF table. (See
Table 82.)
c. Set Function to Normal (Setup > Settings > Traces > Function > Normal).
d. Press the Peak key on the Markers control bar.
e. Adjust the RF signal generator amplitude to produce a signal level within
1 dB of the Reference Level. Record this value as the carrier level.
f. Set the RF signal generator frequency to the frequencies in the table Center
frequencies and signal generator frequencies for Half-IF . (See Table 82.).
g. Set Function to Avg (VRMS) (Setup > Settings > Traces > Function >
Avg (VRMS)).
h. After the averaging has completed, press the Peak key on the Markers
control bar to move the MR marker to the peak signal value.
i. Read the marker amplitude (in dBm) at the upper-left on the display.
Subtract the carrier level (step e) from the spurious signal amplitude
(step h) to convert it to dBc.
j. Enter this value in the test record.
7. Repeat step 6 for each entry in the table.
