Am Subsystem - Hantek HDG 2000 Series User Manual

5.2.1 AM Subsystem

The AM subsystem allows you to add amplitude modulation (AM) to a carrier waveform.
SOURce<n>:MOD:AM:DEPTh <depth>|MINimum|MAXimum
SOURce<n>:MOD:AM:DEPTh? [MINimum|MAXimum]
Parameter
0% to 120%, default 50%
Set the modulation of CH1 to 50%: SOURce1:MOD:AM:DEPTh 50
 To achieve modulation depth greater than 100%, output carrier amplitude may be reduced.
 With AM:SOURce EXTernal, carrier waveform is modulated with an external waveform.
SOURce<n>:MOD:AM:INTernal:FREQuency <frequency>|MINimum|MAXimum
SOURce<n>:MOD:AM:INTernal:FREQuency? [MINimum|MAXimum]
Set frequency of modulating waveform. The waveform chosen as modulating source will operate
at that frequency, within waveform frequency limits.
Parameter
2 mHz to 500 kHz
Set the modulation frequency of CH1 100Hz：SOURce1:MOD:AM:INTernal:FREQuency 100
 When you select an arbitrary waveform as the modulating source, the frequency changes to
the frequency of the arbitrary waveform, which is based on the sample rate and the number of
points in the arbitrary waveform.
 This command should be used only with the internal modulation source
INTernal).
SOURce<n>:MOD:AM:INTernal:FUNCtion SINusoid|SQUare|RAMP
SOURce<n>:MOD:AM:INTernal:FUNCtion?
Selects shape of modulating waveform.
Parameter
SINusoid|SQUare|RAMP, default SINusoid
Select a square wave as the modulating waveform of CH1:
SOURce1:MOD:AM:INTernal:FUNCtion SQUare
 This command should be used only with the internal modulation source
INTernal).
 Pulse and DC cannot be carrier waveform for AM.
