Thanks a lot! :) I'll do my best to improve for future videos.

I just double checked, and even when I have it set to a short timebase setting, triggering in "Normal" mode, the fastest pulse rate I get out of the Auxout port is 33Hz. As I increase the timebase and grab more points, it only goes down from there. But surely it's triggering on the waveform more frequently than 33Hz? Given that the waveform update rate is supposed to be 130k waveforms/sec according to the spec sheet? I'm using a very fast scope to look at the Auxout signal.

Yes, I completely forgot. :palm: I got too used to the AutoRange mode haha...

--- Quote ---On mine I can select horizontal/vertical/level independently (see image). Does it scale all three or just the horizontal on this new one?
--- End quote ---
Forgot to respond - yes, it's the same. You can select all three individually. I just had vertical scaling disabled in my video since I didn't want it to jump around. When I had more than one channel enabled, the vertical scaling was often different for each channel in AutoRange mode, even with an identical signal, which was odd. It works very well for a single channel though.

Further investigation needed...  :o

What's your opinion of the joysticks? I'm wondering if you put your index finger on the top edge of of one, can you push it to do an "up"?

ie. Can you do do up/down by push/pull on the edge of one?

In the video you seem to use your thumb more.

What's the response like when you want to move the trigger position long distances left/right? This one probably needs a video demonstration....

Definitely. It's still easier to put your thumb on them (they have grippy textured tops) and move them that way, only because if you try to move them from the edges, the other buttons may get in the way. The trigger joystick can be grabbed easily from the sides though, and it's easy to move left/right as you describe (which selects trigger channel #). They're also easy to push as buttons, without accidentally tilting them into one of the up/down/left/right positions. To be honest, they do feel good to operate.

The other thing is that unlike a knob that you'd have to keep rotating, you can simply hold a joystick in a particular position (tilted left or right). There is software acceleration, which means that the scrolling speed will speed up over a few seconds, to a point, and then keep scrolling at a "comfortable" speed (slow enough so that you could still watch the waveforms).

I'm honestly neutral on the joysticks. Both joysticks and mechanical rotary encoders will fail over time. Joysticks will probably fail a bit more predictably. I generally prefer knobs, but I don't mind these particular joysticks at all.

I haven't noticed any delays in waveform scrolling at all, regardless of number of points or channels. One of the worst things would be to have some intermittent delays (like on some Tek scopes), but it's pretty smooth sailing with this one at least. Even with all channels enabled and with max points, you can scroll continuously with the joysticks. There are no "jumps" or stutters or anything.

I loved the display of "NaN" in your video when the serial data wasn't updating.  :-DD

You dedicated a lot of time to that bug but really I don't think many people will be decoding 8MHz RS232 data. I mostly do I2C with mine. The I2C decoding and trigger modes work very well. It also shows all the ACKs and NACKs in the decode.  :-+

I'm surprised they haven't added statistical mode yet. I suggested it to them over a year ago and it seems like it should be really, really easy to do. There's plenty of space for a 'stats' button next to the on-screen cursor on/off buttons.
