RF GENERATOR
AFGen1 To
This field has two subfields:
• The upper field sets the destination port for audio frequency
generator 1
• FM -RF generator FM modulator
• AM -RF generator AM modulator
• Audio Out -AUDIO OUT connector
• The lower field
• sets FM modulation deviation if the upper field set to FM
• sets AM modulation depth if the upper field set to AM
• sets the amplitude of audio signal (volts RMS) at the AUDIO
OUT connector if upper field is set to Audio Out
• turns off the AF generator if the
Yes On/Off key is pressed.
Operating Considerations
Simultaneous FM and AM, using both AF generators is not allowed.
AF generators 1 and 2 are automatically turned off any time the CDMA
screens are displayed. This prevents accidental amplitude or frequency
modulation of the CDMA carrier. The AF generators are turned back on
when you exit the CDMA screens (if they were previously turned on).
