Modulation waveform frequency settings
When the modulation source is internal, it can select shift frequency between the carrier wave
frequency and hopping frequency. Turn on 3FSK modulation mode to set the frequency, the range
is between 1uHz~2MHz, default 100Hz. Rotate multifunction knob, push direction key or tap
ModFreq tab to pop-out visual numeric keyboard to enter values and select unit in modulation
setting interface.
Comperhensive example
In FSK modulation mode, set an internal 2kHz,1Vpp sine wave as a carrier wave, set HopFreq1
to 1kHz, set HopFreq2 to 5kHz, make the carrier wave and hopping frequence shift between
within 100Hz frequency. The settings steps as following,
1)
Turn on FSK modulation mode: tap CH1 → Modulate → 3FSK accordingly.
2) Set the parameter of the carrier wave signal
Tap Base to select sine as the carrier wave (the default option is sine), so this step has no
change.
Tap Freq to pop-out visual keyboard to enter 2kHz.
