Add a vertical line across all channels that tracks the mouse cursor so that it is easy to see the time relationship between events in multiple channels. This is likely to be especially useful when eyeballing digital and analogue events.

For bonus points provide voltage readouts on each analogue channel so that the analogue voltages across channels are easy to see when a digital event happens.

Any update on this?

No updates on this at the moment. We'll post here in case we do. We've been working on other priority projects.

Something like this is what I would appreciate for each vertical marker. It would be very useful for me when I document measurements. It is a feature that many oscilloscopes have.

Mitch

Good idea. A kind of "live / temporary cursor". Probably should be able to enable/disable it. Indeed, I could see simply enabling it with something like "hold shift down" and the cursor appears. Let go of shift, and the cursor goes away.

Related useful features is to show the digital level in the channel overview to the left, so the digital level for different channels can be seen at the same time.

Also, make the tab and shift-tab jump to next change of a selected digital channel. This is very useful when searching through a long capture in order to find a specific event.

Peter Jaquiery

A possible improvement on this suggestion is to provide up or down pointing arrows ion the cursor in the middle of each digital channel to indicate if the signal is high or low at that point. That avoids needing to look away from the cursor to figure out what the state of the signal might be at that point, especially if the trance has lots of nearby edges in that region.

Actually the arrows aren't really needed. A dot in the middle of each trace and noticing that the signal was above or below the dot would do the same job. There is also an idea for shading the area below the trace when the signal is high that would achieve the same end and haw wider benefits.

Peter Jaquiery

I strongly agree about tab/shift tab for moving forward and back among edges. That should probably be an idea on its own.

This could be a potential alternative to my overlay signals suggestion.

Peter Jaquiery

I see the two options as providing different advantages. The overlay is a great way to get an overview of differences, but could become very cluttered. The full height cursor is great for examining the relationship between a few edges precisely, but doesn't give an overview.

Saleae

I agree. Adding the cursor is much easier though :)
We're looking into that
