How Do I Check Scope Probes?

Even good quality probes are pretty sensitive to mistreatment, and upper bandwidth response plus high voltage safety is easily compromised by crimping, deformation etc. I always keep my expensive probes out of reach and use cheap Chinese for normal uses. To test if a probe is within specs, you need a scope of over 4 times their bandwidth and a source with less than 1/4 of their expected rise time, so if you're happy with your 10 MHz response, just forget the rest. S.M.

I would check performance over a range of frequency and voltage, as well as an impedance test.

As for the kid, I have a similar experience with a young guy that knows everything, so I don't even try to teach him anything. I am keeping an eye out so nobody gets injured while he alienates the people that he will need to help him be successful.

OK. Thanks, guys.

I have a youngish PhD who has decided to "mentor" me,
RAOFPMSL.
Every scope I've ever seen has a probe cal connection. You hook up the probe and adjust the trimmer to give a clean square wave. You are calibrating the probe to the particular scope.
Or am I missing something?
Presumably you have shown him how to tie his shoe laces and pull his trousers right up?

What are the probes rated for (voltage, MHz, capacities...) and your general usages. Are you working in a small range of what the equipment can work in? Or do you run the full range of what the equipment can work in?

Oh, here a PDF link from Tektronix on the ABC's of Probes. It may give some insight.

One other thing if the bends radius were 3-4 times the cable dia. there should not be any problems with the cables being damaged.

If they were kinked or folded tight there could be internal insulation damage which would affect the cable impenitence and voltage capabilities.

Although in the long run giving them a little love and care will make them last a lot longer.

Hey, I appreciate that link. I'll have to make copies and conveniently "leave" them where others can read them.

Impenitent cables are intransigent, and must stay locked up. Give the PhD student the task of going though the Tek ABCs and procedures to calibrate them

Sorry !

This is only for companies.

All you need to do is create a faked company of just 2 letters and a few numbers in the zip code.

I used

rr for my name

12 dfrs st

Rochester NY, 14021 a valid Rochester zip code (I think)

and 123-456-7890 for my phone number and the download was activated.

the bots are easy to fool

Thanks.

Astonishing !

I used "Home" in "Industry Name" and "Free-Lancer" in "Position" column. This all worked. As they had the intention to share.

Before this I had been asking Tektronix for free publications [Hard copy] and collected a fairly good library which I donated to an institute on my 65th milestone. Now @ the 78th have to fool them?

How good were the days GE-[We have no connection with GE-UK or such words] sent me a complete collection of their Application Notes, RS components, HP [When it was Hewlett-Packard not ...].

I remember that to a UK manufacturer of ECG machine I sent a feedback about a device with suggested modification to a TO-3 heatsink mounting.

They sent its Service Manual, Modified kit, and thanks.

A UK Software: Classicboard [Text]: I asked my son in UK to purchase. He wrote them to which their reply was tha a free version is available, try it, if it serves your father why to purchase pro.

And I had been using it till XP by registering some file shown by error.

Lot of free ... and which made my life easy Irfanview is the best in my view.

I started it when the publisher was a university student.

If you crimp the coax, I would expect that it would make a discontinuity in the characteristic impedance, causing reflections. If you connect it to a square wave source (calibration signal), you might see ringing on the transitions.

Just send him the bill for new cables! - that should make a dint in his allowance and perhaps help him to learn a lasting lesson as you did.
