FSK Modulation

Background

The FSK Modulation function can set the hop
frequency (FSK Hop) and the frequency-shift
keying rate (FSK Rate). FSK Modulation essentially

frequency at a rate determined by the FSK rate
frequency.

Steps

1. Set the carrier waveform and

frequency. You can set the carrier
waveform and frequency in the
Selecting a Basic Waveform section.
