A few specific questions for SDS2000X HD owners (or possibly any SDS owners)

Hi Spike, are you still working on this ?
I've been trying to accommodate the original Pull Request to work with the SDS2000X-HD.
I agree with you, the orignal PR is quite a mess and needs a lot of rework, I understand why it has not been accepted by the maintainers of Sigrok codebase.
Maybe we can join efforts ? What Siglent model do you have ?
Right now I have both analog and digital signal capture working with a given time-base. Next step is to have everything work fine when changing settings.
Best,
Frederic.

just 2 cents worth, but if you guys managed to become spark plugs that get Sigrok on a path to playing nicely/increasingly well with Siglent oscilloscopes, especially the HDs, it could be a significant win for Siglent users, Siglent, and maybe even Sigrok… which could be a win for more device manufacturers and more users

Well I don't see why we could not make Siglent HD scopes play nicely with Sigrok/PulseView. They have a very comprehensive SCPI command set and my first tests are pretty encouraging.
But I struggled a lot at the start with strange behaviors of the original connector that as a 7 seconds "timeout" parameter set on the SCPI driver.
This poorly named parameter is used to set the duration the driver waits after sending a command before reading the result from the scope.
7 seconds is a lot of time to wait when you hit the run button to get the acquisition result !
Anyway I changed it to 50ms (the value used on Rigol driver, which the Siglent one seems to be based on) and everything gets much more snappy !
I had to change the buffer reading logic to have it work that way, that must be the reason why it was originally set to 7 seconds.

Anyway if you guys can give me a testimony on how the original driver actually behaves, it would be greatly appreciated !
Do you have to wait for 7 seconds before Pulsview window gets updated or is it something specific with the HD ?

kripton2035:
with pulseview on a salae clone, you don't wait for the window to get updated.

Thanks for the feedback kripton2035, but my question was more directed towards Siglent users.
I was not able to find any video or demonstration of PulseView connected to a Siglent scope.
