After selecting AM, you can set the AM frequency and AM depth of the
modulating waveform.
AM Frequency: press AM_Freq to set the frequency of the modulating
waveform. The range is from 1 Hz to 50kHz. For the setting method, please
refer to the introduction in
Set the frequency.
AM Depth: the modulation depth refers to the strength of the AM and is
expressed in percentage. Press AM_Depth to set the modulation depth of
the modulating waveform. The range is from 0% to 120%. When it is set to
0%, the output amplitude is half of the carrier amplitude. When it is set to
100%, the output amplitude equals the carrier amplitude. When it is set to
a value greater than 100%, envelop distortion will occur which must be
avoided in actual circuit; at this point, the output of the instrument will not
exceed 5 Vpp (the load is 50 Ω).
FM: the frequency of the carrier waveform changes with that of the
modulating waveform.
