5.8.3 FSK rate
The FSK rate is the rate at which the output frequency "shifts" between the carrier frequency and the
hop frequency when you select the internal FSK source.
To set the FSK rate, press the FSK Rate softkey. Then use the knob or numeric keypad to enter the
desired rate.
5.8.4 Modulating Waveform Shape
In FSK，the internal modulating waveform is fixed to a square wave with a 50% duty cycle.
5.8.5 FSK Source
When the Internal source is selected, the rate at which the output frequency "shifts" between the
carrier frequency and hop frequency is determined by the FSK rate specified.
When the External source is selected, the output frequency is determined by the signal level on the
rear-panel Trig In connector. When a logic low level is present, the carrier frequency is output. When
a logic high level is present, the hop frequency is output.
