To Set Modulating Amplitude


Press ModAmp to set the modulating amplitude.
 Input the desired amplitude value using numeric keyboard or knob.
 The available amplitude (High Z) ranges from 0 V to 10 V, and the default value is

2 V.


To Set Modulating Polarity


Press Polarity to select the “Positive” or “Negative” of the modulating waveform to
control the output amplitude.

When internal modulation is selected, if the polarity is “positive”, logic low of the
modulating waveform amplitude corresponds to output of the smaller of the two
amplitudes (modulating amplitude and carrier amplitude), while logic high
corresponds to output of the greater amplitude; if the polarity is “negative”, the
situation is the opposite.

When external modulation is selected, if the polarity is “positive”, logic low of the input
corresponds to output of the smaller of the two amplitudes (modulating amplitude and
carrier amplitude), while logic high corresponds to output of the greater amplitude; if
the polarity is “negative”, the situation is the opposite.
