Interesting idea about including probes. 5X is getting down there. I try to keep loading under 10% error and use 10X (500ohms) in many cases. 100 ohm differential termination with another 200 to ground on each leg .... maybe... I guess as long as people understand the limits of the trigger it's fine. Leave it up to them to sort out if it can be used or not. Consider you may be using a delay line with the 5X probe, knocking another 6dB off. A lot to consider. As you said, it's down to price point.
After starting the software, set all offsets to 0. Entering 50 for scale on channel 1 will randomly select 50 V/div or 50 mV/div. I would expect it to be predictable and was surprised that 50V would be valid. Seems easy enough to reproduce.
I have had the software appear to hang. Basically it was displaying wait, but appeared not to be updating the plots as nothing was being displayed on the graph for all 4 channels. Nothing, meaning a blank screen. I changed the scale to 500mV/div, and it remained blank. Offsets all set to 0. I increased the input voltage to 500mVp-p with no triggers. 10MHz. All I did was exit the software and restart, everything was working as expected. I have not been able to replicate this but I have seen the software hang like this before with an earlier revision.
I am curious if you are getting any feedback on the UI. It's easy enough to run but IMO, not very smooth.
It's a real pain to hunt down your waveforms with manually setting the offset and scale. Typing in the scales rather than the drop down selection do allow me to set it to what ever I want, but now its a bigger time waste entering all that data.
I would like to see this thing have some sort of intelligent mode where is autoscales the vertical, locks the start of acquisition to the left, changing the vertical scale resets or at least causes min/max to track. It's the same with dragging the waveform to change the offset, the min/max doesn't track it. It's a constant close waveforms and recreate. Or if I change the vert scale for channel 1, the scale for the min/max don't track it.
Having that start of acquisition time moving all over based on the Base is a pain. I am constantly dragging waveforms.
It's very possible that your customers like the UI. Consider I am up there in years and have used a lot of different scopes, it could just be my bias on how they should work. Years ago, I looked at a brand new logic analyzer from HP. That is all I have ever used and for the most part, they all drove the same. Even with the touch screen and single knob. This new thing was like they had fired the entire staff, brought in new management that had no idea what a LA was, and decided to make a product that worked (in their minds) better than the old systems. Or they had no idea how their old products drove. To me it seemed they were trying to target software people for the end user rather than hardware. It was so bad, I gave a simple test to other EEs to see if they could run it. In the end, the software was why I didn't procure it.
A few years ago I wanted to buy a better VNA for home hobby use. Get out of the 1970s... I looked at Picotech. Really liked the hardware. Price was high but specs are good. 4-receiver.... Then I tried their software and ditched the idea. I reached out to them last year to make a series of videos on their VNA but no bites.
Point being, software for these is IMO, is every bit as important as the hardware. If it drives different than every product out there, it may not get a lot of acceptance. Again, MO.
