How to genereate PWM by using AWG for Picoscope 2208B

Post by avi.patel001 »

Hello Folks

I am working on the PicoScope 2208B, Can We generate the PWM signals by using AWG? If yes then Can you please guide me through the procedure?

Thanks
Avi

Hi Avi,

Unfortunately, you can't modulate the duty cycle of a pulse waveform in the Arbitrary Waveform Generator, as you can only use the fixed version of a customized waveform. Some of our Data loggers have Digital outputs that can be modulated to provide a PWM waveform (in PicoScope 6, or using our SDK), such as our PicoLog 1216, and DrDaq, but not the PicoScope 2208B.

With some clever manipulation of functions it may be possible to generate a Math Channel that is pulse width modulated by some other function, but this would be a bit pointless, as it would not be able to generate any stable waveform for external use.
