To Set Modulating Phase
Press Phase to set the modulating phase.
Use the numeric keyboard or direction keys and knob to input the desired phase
value.
The phase range is from 0° to 360° and the default is 180°.
To Set Modulating Polarity
Press Polarity to select the “Pos” or “Neg” polarity of the modulating waveform to
control the output phase.
In internal modulation, set the polarity to “Pos” and the generator would output the
carrier phase when the modulating waveform is logic low level and output the
modulating phase when the modulating waveform is logic high level. The situation is
the opposite when the polarity is set to “Neg”.
In external modulation, set the polarity to “Pos” and the generator would output the
carrier phase when the external input signal is logic low level and output the
modulating phase when the external input signal is logic high level. The situation is
the opposite when the polarity is set to “Neg”.
