3-4 Configure ΦM
During the following procedures, you can learn how to generate phase modulation
RF carrier wave with the following characteristics:

The carrier wave frequency is set as 3.0GHz.
 The power electric level is set as 0dBm.
 Phase offset is set as 0.25 radian.
 Modulation rate is set as 30kHz.
3-4-1 Set carrier wave frequency
1. Press PRESET .
2. Press the FREQ hard function key, and input 3 GHz.
At the moment, the FREQUENCY region of the display screen will display
3.000 000 0GHz.
3-4-2 Set RF output amplitude
Press the AMPT hard function key, and input 0dBm.
At the moment, the AMPLITUDE region of the display screen will display 0.00dBm.
3-4-3 Set ΦM Dev and ΦM Rate
1. Press the FM hard function key.
2. Press the FM/ΦM soft function key.
At the moment, the first-level menu of the PM soft function key will be
displayed.
3. Press the ΦM/ Dev soft function key, and input 0.25 rad (Radian).
Thus, the PM Dev is changed into 0.25 rad.
