“External” modulation source. The default is “Internal”.
1. Internal Source
When internal modulation source is selected, the modulating waveform is a
square with 50% duty cycle.
2. External Source
When external modulation source is selected, the generator accepts external
modulating signal from the [Aux In/Out] connector at the rear panel.
The external modulating signal of FSK must be a square wave which complies
with 5V CMOS level specification.
To Set Key Frequency
When internal modulation source is selected, press Key Freq to set the rate at
which the output frequency
shifts between “carrier frequency” and “hop
frequency
”.

Use the numeric keyboard or arrow keys and knob to input the desired
value.

The key frequency ranges from 1 mHz to 1 MHz.

When external modulation source is selected, this menu is hidden.
To Set Hop Frequency
The range of the hop frequency depends on the carrier frequency currently
selected. Press Hop Freq to highlight the parameter, and then use the numeric
keyboard or arrow keys and knob to input the desired value.

Sine: 1uHz~ maximum frequency

Square: 1uHz~ maximum frequency

Ramp: 1uHz~ maximum frequency
