Hop Frequency Setting

After enabling FSK function, the default of hop frequency is 2MHz. If need to change, press

Param → HopFreq in turn. Settable range of hop frequency is determined by carrier wave

waveform. See Carrier Wave Frequency Setting

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 1MHz, the default rate is 100Hz. If need to change, press

Param → Rate in turn. Please refer to Carrier Wave Frequency to set up the frequency.

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:

Enable Frequency Shift Keying (FSK) Function

Press Menu → Mod → Type → FSK in turn to start the FSK function.

Set Carrier Wave Signal Parameter

Press Carrier → Type → Sine in turn to select sine wave as carrier wave.
