H Press the TRACE/AVG key on the front panel.
H Press the Trace 1 Type... side key and select Average.
H Press the Number Of Averages side key and set the value to 50.
H Press the MARKER SETUP key.
H Press the Markers side key to select Delta.
c. Set the generator controls:
Level . . . . . . . . . . . . . . . . . . . .
d. Hook up the signal generator: Connect the generator output through a
50 Ω N-N coaxial cable to the analyzer INPUT. See Figure 4- -16.
2. Check spurious response:
a. Modify the generator controls: Set the generator output frequency to the
value as shown in Table 4- -6 (initially 10 MHz).
b. Modify the analyzer controls:
H Press the FREQUENCY/CHANNEL key on the front panel.
H With the Center Freq side key, set the frequency to the same value
as the generator output using the numeric keypad.
c. Measure the amplitude:
H Press the MARKER SETUP key.
H Press the Select Marker side key to select 1.
H Press the PEAK key and then the MARKERS: B (marker down)
key once to place the first marker at the peak on the noise floor.
H Press the Select Marker side key to select 2.
H Press the PEAK key to place Marker 2 on the signal peak.
H Read the delta marker readout (Δ1- -2) on the screen. Check that the
components other than the carrier meet the requirement as shown in
Table 4- -6 (initially - -73 dBc).
- -5 dBm
