I did look at making one with a Hall sensor - the electronics isn't a problem but the difficulty arises (for me at least) in cutting the slot in a ferrite ring to put the sensor in or even splitting

I checked on ebay and the cheapest adapter I could find was almost $20; not very sensitive (1 mV per Ampere) and no idea of bandwidth. If anyone knows of a project to create a current probe I would be

Mine has a bandwidth of 20KHz (probably 1/2 that is usable) which is more than adequate for my needs. The only problem with it is the zero drifts, but I can live with that. Dave

Talk about it ! :-/ I had my 2232 for a year, was working just fine. Then I had to do some work on it, UNrelated to the PSU. Once I was done, put it back together, went for a test drive to make sure

If you only need low frequency the LEM brand hall effect sensors, I believe Allegro also makes chip based ones, can be an option. Also remember you can put 10 turns through if you need more

I quite often have a need to sense small currents (~10-200mA) and have always wanted a clamp on current probe but even the used ones for a scope are out of my budget. A series resister is one solution

Hi Roger, Thanks for your comments so far.

Re: vomit smelling screwdrivers and : Cellulose Acetate, and Cellulose Acetate Butyrate. I /think/ both get the white-crud. ? It's the CAB that breaks down and releases butyric acid, which smells

I don't want my comments to be a source of disparagement of Leo's work. I haven't spent a great deal of time studying what he has done, but in all of the scope pictures he has presented, there is very

Consider the time scale on Leo's plots and the response of the scope he's using which is what you are seeing in the calibration plot. I can't find my plot right now as my bench is undergoing at

I think Shakespeare warned us of that Chuck? "The tongues of mocking wenches are as keen as is the razor's edge" ...oh....sorry........w*R*enching....misread the subject..... Adrian

That is absolutely true! Should have spotted the potential for confusion since my son is a bass guitarist :-)

One of the less bad routes is to a local hackspace/makerspace. My local one has had a Tek 2245 , a Telequipment DM63, and lots of drawers of components. A problem is that youngsters think

There were a couple different types of plastic used for tool handles, and one develops a white film as it decomposes. I've only seen it in colored handles, but once it starts, it seems to keep eating

That hasn't been my experience, and the same wrench was sold with or without the plastic cover. They have the same weight, since their isn't that much plastic. It was pre 'Cooper Tools' manufactured

I used to have a cheap hammer that someone broke off most of the head, driving a 16 penny nail. It was in the box of 'loaner tools' as a joke. :) OTOH, someone could have been badly hurt, or killed by

It should be quite obvious if compared to an unmodified 7B80. This is what the mod manual insert says: // 7B80 MOD GB This manual insert describes MOD GB as it applies to the Tektronix Time Base

That can be confused with a type of guitar pickup. :) Michael A. Terrell
