Finally decided to pull the trigger and get me an Analog Discovery 2. This makes so much sense for the stream (overlay the data), and for pinball repair (portable scope/meter/analyzer).
Analog Discovery 2 - USB Oscilloscope and Logic Analyzer https://digilent.com/shop/analog-discovery-2-100ms-s-usb-oscilloscope-logic-analyzer-and-variable-power-supply/
@sydheresy I quite like mine and I use it in pretty much the same way -- scope overlay for OBS on stream. I actually saw one for sale for $180 used at a local pawn shop last week if you know anyone else who might wanna pick that up. Can facilitate.
@48kRAM egg! now you tell me. 😆
yeah, my current o-scope is great, but it's not really "portable" and the software for capturing the screen is absolute dogshit. So this solves all that, gives me a few new tools, plus this is gonna make pinball repair so much easier. the data logging alone is gonna be great as I usually have to measure large multipin connectors!
@sydheresy Sorry mate. :(
But yeah I had the same issue w/ my scope. Tried to set up the PC software and it was terrible. Looking forward to seeing this integrated on your stream soon
@48kRAM yeah, the software had a frame rate of 0.4/FPS, ha horrible 2 second lag, AND it locked out the physical interface; so you were stuck with the crippling speed.
@baldengineer speculated that it was just taking screenshots and sending them off to the software via USB 1.0.
@sydheresy @baldengineer Not a bad guess. I think the Rigol stuff actually dumps the data points as a CSV and then plots it in a window at about, yeah, 0.3fps
@48kRAM @sydheresy I don't think it is doing just the waveform data. Since that would be the PC is re-creating the scope screen, which means it would have to query the scope's entire setup to re-create the screenshot with controls and such.
The simpler solution would be for the software to use the :DISP:DATA? SCPI command to get a bitmap/screenshot instead.
@48kRAM @sydheresy It has been a long time since I used their PC software, so I don't entirely remember what it did.
I just remember doing something, getting the screenshot auto-updating, and then finding that SCPI command.
OWON's software, on the other hand, can query the screenshot, but it re-draws the waveform in a native PC UI/grid.
It's equally terrible to work with.
