They seem to have been bought together and are definitely from the same manufacturer, Vernier, which supplies sensors, loggers and interfaces to schools. However, as above, we have found in another box a different interface which does fit the sensors, but nothing (yet) which fits that little...

We have found another interface unit which does fit the sensors we have, but interface in that picture (we have quite a few of them) don't seem to fit any of the sensors we have. Little stops Probably.

Oscilloscope cables - the cables which (presumably) were supplied with the oscilloscope. Regarding the other cables, they physically don't fit together. They are part of a kit with various sensors and a few interfaces, but they don't seem to be compatible. One of them seems to be exactly the...

Thanks, I saw mention of the x10 in the probe on one of the videos I watched but had forgotten it. The signal generator and the scope both have coaxial connections so that will mean either a bit of fiddling or a different cable.

No, these are the Vernier connectors

Good news, today while looking through a box of (apparently unused) Vernier sensors we have, I found two oscilloscope cables! They are the type with the probe but will do the job nicely. But, while looking through those Vernier sensors (photogates, light sensors, pd, pH etc) we have found that...

Now that I have a better idea of what I'm doing (or at least, a bit more confidence) I'll have another good look at the manual and help videos. I might be in a better position now to relate what they are doing to what I want to do.

I know! I tried to set the trigger and lost it completely so switched to Channel 2. But.....I had taken the little blue triangle to be the centre line, that's how I centre my trace. I might not get time today but will have another look at the trigger thing. I haven't tried that yet - I've been...

Look!

Oh, I'd love to have an old CRO one - but unfortunately I need to make the most of what I have. Thanks and yes - I'd love to be able to get to this stage. It's a question of finding the time though. I have vague recollections of attempting to display sound waves though a digital oscilloscope...

An update First, practising without children present: to display the difference between the dc output from a battery and the ac output (plus rectified dc) from the powerpack - autoset gave a nice clean ac trace and also displayed the battery trace nicely. (Deeply embarrassed that I didn't just...

It's working it's working it's working!!!!!!!!!!!!!!!!!!!!! :smile::smile::smile::smile::smile::smile: More later, Y11 are coming in 2 minutes

Thank you all for your replies. It's 0710 here and I've just got to school so will make time to read them properly later. I'm old, and used to the old electron tube scopes which connected via a coaxial cable with two plugs on the other end, and have never had to think about grounding them. The...

Thanks for replying. I will have a look for the probes. At present it comes with a cable which has two crocs at the end. I did have a look at the manual (online) but then didn't ahve time to set it up again. The one I saw in another school did come with the probe type attachment and it's...

My new school has a Gwinstek oscilloscope rather than the old fashioned electron tube type. It's not the first time I've found one of these in a school and so far, I've never been able to make them usable or useful for high school students. Has anyone managed to use one successfully to...
