Simple Oscilloscope Question

[tautech]

Let's have a little deeper look.....
SDS1104X-E
We know when History is correctly used a little over 50 Mpts of waveform record is available however the memory depth selected by the user has an impact on how many frames of history are available for viewing in a History capture.
In this series of screenshots from a single History capture with the scopes mem depth set to 1.4 Mpts we have some 500 frames available.
What to do with them ?
Navigate is the best where we can select either a time or history frame to migrate to and play the whole record in any of 3 different speeds.

A selection of captured screenshots for study............

tautech, Thanks for the images,

Basically, I think you are saying to set display at a slow sweep rate, use History to find your frame of interest, then change to a higher sweep rate and use Navigate to play the frame as needed.

Okay, that is what I've been doing and I can get what I want eventually.

The key is to record at very slow sweep rate relative to the signal. Which is not normally how I like to use my scope. So a recapture is usually required.

For what it's worth (I'm a newbie to digital scopes), it seems to me the people here who say this is a problem have a point. The ability to zoom out, as Dave said in the video, seems like a good fix.

Thanks to all for the comments.

P.S. I managed to use zooming, but I'm not sure it's any better.

Your signal might be too fast but in some cases I use 'roll mode' and stop the oscilloscope manually at the point where the signal changes. From there you can zoom in on the part of the signal that is misbehaving. But again, a 200Hz signal might be too fast for this method unless the change you want to inspect is  very obvious (like the signal dropping out).

For what it's worth (I'm a newbie to digital scopes),

The power of a DSO is capture and inspection however even more powerful is the trigger suite.
This takes longer to master than basic DSO use.....after some years using them I learn more about it.
Simple single shot captures like those above were only done on that single burst so to demonstrate how we might navigate through it using History and a wee peek of the features available.

We could of course use Search to find particular waveform points of interest within the burst for deeper inspection.
I have a play with Search here:
