After enabling FSK function, the default of hop frequency is 2MHz. If need to change, press
Parameter→Hop Frequency in turn. Settable range of hop frequency is determined by carrier wave
waveform. See the following table for setting range of each carrier wave frequency:

FSK Rate Setting
When modulation source is internal, the moving frequency between carrier wave frequency and hop
frequency can be set. After enabling FSK function, FSK rate can be set and the settable range is 2mHz to
100kHz, the default rate is 1kHz. If need to change, press Carrier Wave Parameter→Rate in turn.
Comprehensive Example
Firstly, make the instrument work in frequency shift keying (FSK) mode, then set a sine wave with 2kHz
and 1Vpp from the internal of the instrument as a carrier wave signal, and set hop frequency to 800 Hz,
finally, make carrier wave frequency and hop frequency move between each other with 200Hz
frequency. Specific steps are seen as following:
1) Enable Frequency Shift Keying (FSK) Function
Press Menu→Modulation→Type→Frequency Shift Keying in turn to start the FSK function.
