FSK Carrier Frequency

The maximum carrier frequency depends on the carrier shape. The
default carrier frequency for all carrier shapes is 1kHz. The voltage
level of the Trigger INPUT signal controls the output frequency
when EXT is selected. When the Trigger INPUT signal is logically
low the carrier frequency is output and when the signal is logically
high, the hop frequency is output.

Panel Operation

1. To select the carrier

frequency, press the FREQ/
Rate key.

2. The FREQ parameter will become highlighted

in the parameter window.

3. Use the selector keys and

scroll wheel or number pad
to enter the carrier
frequency.

4. Press F2~F6 to select the

FSK frequency units.
