denotes the amplitude veriation degree. Press Depth to set AM modulation
depth and the range available id from 0% to 120%. In 0% modulation, the
output amplitude is half of the carrier waveform amplitude; in 100%
modulation, the output amplitude is equal to the carrier waveform
amplitude; when the modulation is larger than 100%, the envelope
distortion will be generated and the actual circuit must be avoide. At this
point, the output amplitude would not be exceed 5 Vpp (the impedance is
50 Ω).
Frequency modulation: the frequency of the carrier waveform varies with
the amplitude of the modulating waveform.
After FM is selected, you can set the frequence of the modulating waveform
and the FM modulation frequency:
Frequencey: press Frequency to set the frequence of the modulating
waveform and the range available is from 1 Hz to 50 kHz. For the setting
method, please refer to the instruction of the “
To set frequency”.
Deviation: press Deviation to set the deviation of modulating waveform
frequency relative to the carrier waveform frequency and the range
available is from 0 Hz to the carrier waveform frequency currently set.
2. To select modulating waveform
Press Shape to select Sine, Square, Ramp and Noise as the modulating
waveform.
