1. Set up the 682XXB/683XXB as follows:

a. Reset the instrument by pressing SYSTEM, then Reset. Upon reset, the CW Menu is dis- played.

b. Press Edit F1 to open the current frequency parameter for editing.

c. Set F1 to 5.0 GHz.

2. Set up the Spectrum Analyzer as follows:

a. CF: 5.0 GHz

b. Span/Div: 100 kHz (1 MHz across the display)

3. On the 682XXB/683XXB, make the following set- tings:

a. Press MODULATION, then FM. The FM Status menu is displayed.

b. At the FM Status menu, press Edit Dev. and set the deviation to 0.240 MHz.

c. Press Edit Rate and set the rate to 99.8 kHz.

d. Press On/Off to FM on.

4. On the 682XXB/683XXB, use the cursor control key to place the cursor under the last 0 in the de- viation setting (0.240 MHz). While observing the first Bessel null (Figure 3-9), increase/decrease the deviation frequency with the cursor control key to reduce the carrier as low as possible.

5. Record the FM deviation frequency, displayed on the 682XXB/683XXB, on the Test Record.
