Using Analog Modulation (Option UNT)
Configuring the LF Output (Option 303) 
The  RF On/Off hardkey does not apply to the LF OUTPUT connector.
Configuring the LF Output with an Internal Modulation Source
In this example, the internal FM modulation is the LF output source. See Figure 4- 3.
NOTE Internal modulation (Int Monitor) is the default LF output source.
Configuring the Internal Modulation as the LF Output Source
1. Press  Preset.
2. Press the FM/ΦM hardkey.
3. Press  FM Dev > 75 > kHz.
4. Press  More >  Setup FM Source >  FM Rate > 10 > kHz. 
5. Press  Return >  Return >  FM Off On. 
You have set up the FM signal with a rate of 10 kHz and 75 kHz of deviation. The FM annunciator is 
activated indicating that you have enabled frequency modulation.
Configuring the Low Frequency Output
1. Press the LF Out hardkey.
2. Press  LF Out Amplitude > 3 > V. 
3. Press  LF Out Off On.
You have configured the LF output signal for a 3 volt sine wave (default wave form) output which is 
frequency modulated using the Int Monitor source selection (default source).
