2) External source
When the modulation source is external, the modulation wave and frequence will be hidden in
parameter list. The PM offset is controlled by the ±5V signal level on the external analog
modulation input terminal (Modulation In connector) on the back panel. For example, if set the
phase deviation to 180°, that is equal to +5V of the external modulated signal, the lower external
signal level produces less deviation.
Modulation waveform frequency settings
When the modulation source is internal, it can set the modulation waveform frequency, and
the frequency range is between
1uHz~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 PM modulation setting interface. When the modulation source is external, the
modulation wave and frequence will be hidden in parameter list. Use the external waveform to
modulating the carrier wave. The intput external modulating signal frequency range is between
0Hz~50kHz.
Modulated phase deviation settings
Phase deviation indicates the phase deviation changes between in the PM-modulated waveform
phase and the carrier wave phase.Phase deviation range can set 0°~360°, the default range is
180°. 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.
Comprehensive example
In PM modulation mode, set an internal 200Hz sine wave as the modulating signal, another sine wave
with frequency 900Hz, amplitude100mVpp as the carrier wave signal, and set the phase deviation to 200°,
the settings steps as following,
1） Turn on PM modulation mode: tap CH1→Modulate→FM accordingly.
