Frequency Shift Keying in turn to start the FSK function. The device will output

modulated waveform with current setting.

Carrier Wave Waveform Selection

Press Carrier Wave Parametersoftkey to enter carrier waveform selection interface. FSK carrier waveform can be:
sine wave, square wave, ramp wave or arbitrary wave (except DC), and the default is sine wave.

Carrier Wave Frequency Setting

Settable carrier wave frequency range is different of different carrier waveform. Default frequency of all carrier
wave is 1kHz. The frequency setting range of each carrier wave can be seen in the following table:
