To Set Modulating Amplitude
Press ASK Ampl to set the modulating amplitude。
 Use the numeric keyboard or direction keys and knob to input the desired
amplitude value.
 The range of amplitude (HighZ) is from 0 to 10Vpp and the default is 2Vpp.
To Set Modulating Polarity
Press Polarity to select the “Pos” or “Neg” polarity of the modulating waveform to
control the output amplitude.
In internal modulation, set the polarity to “Pos” and the generator would output the
lower of the carrier amplitude and modulating amplitude when the modulating
waveform is logic low level and output the greater 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
lower of the carrier amplitude and modulating amplitude when the external input
signal is logic low level and output the greater when the external input signal is logic
high level. The situation is the opposite when the polarity is set to “Neg”.。
