Learning how to use an Oscilloscope

@inst-tech OOPS, I should have mentioned, this is a push to lock power on rig LED, it needs 12 to 24 VDC. I will use a MOSFET to give them 24VDC and control the MOSFET with either the 3.3VDC (lights but less bright) or add a level converter to change the 3.3VDC signal to a 5VDC.

Thanks for rating the point, that kick started my memory so that I recalled what I just explained. It also explains why I have an IRF520 module sitting on my desk.

I will try to make a diagram when I have it designed (80%) and bread/perf boarded to prove it all works. It's no big deal, I just took Bills Linear PSU and eliminated the switch to bring out 3.3VDC, 5VDC, 12VDC and 2-20VDC posts each with a meter and on/off switch. That way I can have 1 to 4 voltages at once. Hmm, I should really have a total AMPS in there as well but I think it's unlikely. If anything will pull power, it will be the 12 and I have another supply I can use for that if needed.

Thanks again.

At the moment I am trying to get my Pi4 to work with a Logitech Wireless Mouse/kbd combo but no luck yet.

As you can see I have not done anything scope wise for a while. Life and more interesting projects get in the way plus I only have a few days a week and then only a few hours when I can be productive.

Anyway, I have a what I think is a simple and reasonable question, where is the 'screen saver' setting? I would ideally like to leave my scope on all the time I have power on my workbench but I don't want to 'burn in' the idle pattern. Is this something scopes have like our PC screens have, called a screen saver?

Hi Ron,

RE: where is the 'screen saver' setting?

I agree it seems to be a reasonable question, but finding a reasonable answer may be a challenge.

I haven't seen any mention of one, but that means little, as I often fail to spot 'features'.

Bear in mind that the 'operating system' depends on which manufacturer is involved, so I am doubtful if there is a 'universal' answer. The one I have, is based on Android, but I have seen reports that others use different approaches.

Also, the screens are LCD, not cathode ray tubes, so not susceptible to a 'phosphor burn' effect, although I would not rule out some other kind of 'permanent' memory after a long period.

Best wishes, Dave
