Wavegen Sweep to and from

[bryan78]

Is there a way to have the sweep go to and from a start and stop frequency instead of wrap around?  I have tried accomplishing it in a script but I am relying on setting the frequency time and using wait() to switch start and stop frequency.  This leads to un-smooth transfers or the possibility the timing is a bit off and it wraps around before stopping.

Hi @bryan78

Try a custom waveform. The screenshots below show the equivalent for an amplitude sweep, but the principle would be the same for frequency.

 

Frequency modulation could also do it. The equivalent using amplitude modulation is below. It would be easier if you don't need to worry about a consistent frequency at each stage of the sweep, as you could use a normal signal type like a triangle wave instead of a custom one.

Thanks,

Hi @bryan78

You could use Frequency Modulation. Like this goes between 1kHz and 3kHz :

 

The next version will add sweep shape option:

@attila

Appreciate you adding it to the GUI, you're killing it 😃

@artvvb thanks, I will play around a bit more
