2. Connect equipment as shown in Figure 2-3.
3. Set the frequency synthesizer for an output frequency of 40 MHz
and an output power level of -10
dBm.
4. Key in the following analyzer settings:

and (PEAK SEARCH).
7. Press MARKER la] and set the frequency synthesizer to
40,008,OOO
Hz. (See
‘Ihble
2-3.) Press MARKER (PEAK SEARCH].
8. Using the procedure of steps 5, 6, and 7, measure the frequency
separation of the indicated signals for each setting in
‘fable
2-3.
The MARKER A frequency should be within the limits given in the
table.
