Modulation waveform frequency settings
When the modulation source is internal, it can set the modulation waveform frequency, and the frequency range is between
1μHz~2MHz, the default range is 100Hz. Rotate multifunction knob, push direction key or tap ModFreq tab to pop-out visual
numeric keyboard to enter values and select unit in ASK modulation setting interface.
Comprehensive example
In ASK modulation mode, set an internal logical signal 300Hz as the modulating signal, another sine wave with
frequency 15kHz, amplitude2Vpp as the carrier signal, the settings steps as following,
Note: It can only set the frequency of this signal, the frequency is the ASK rate. Logic signal is self-configurable by
the instrument.
1） Turn on ASK modulation mode: tap CH1→Modulate→ASK 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 15kHz.
Tap Ampl to pop-out visual keyboard to enter 2Vpp.
