Re: TDS3000B calibration
Calibration means: first ""measuring"" a set of parameters from a standard calibration generator (rise time, DC gain, time interval, BW, etc....) and then
"adjusting" the instrument to bring those

Re: TDS3000B calibration
Amirb, you mean that part? I haven't read all posts. I should add that it's as irrelevant for analog 'scopes, apart from the fact that with the latter, trace intensity suffers too much at lower

Re: TDS3000B calibration
It depends on what is needed. A pulse generator like John Williams' is suitable for checking or adjusting slew rate, which means maximum HF content. That is not the same as adjusting for optimum

Tek 222/224 Battery Replacement
Hi all,
One of my customers approached me a few weeks ago about a project to replace the sealed lead acid battery (now unobtainium) in Tek 222/224 scopes with lithium ion cells that presumably will

Re: TDS3000B calibration
Leo Bodnar's (no affiliation) fast pulse generators have 40ps max. rise time and 10 MHz repetition rate. BTW, the repetition rate is completely irrelevant for digital 'scopes.

Re: Tek Blue Paint
Bert,
There has been posted (on another list and a long time ago) a method to repair scratches and bare spots on radios with wrinkle paint.
In summary: you make an impression with rubber

Re: Tek 2710 suddenly won't power up??
You can start by downloading an operating and service manual from here:

I think in general the first thing most people do is open it up and take a look. Next up is

Re: Tek Blue Paint
I'm very seldom happy with the results of my painting efforts.
The main thing I was trying for here was to touch up some scrapes on my Tek scopes and so far that's not working out.

Re: Tek Blue Paint
I use one of the cheap HLVP guns from HF; it can be used for latex
or enamel, just has to be thinned properly. It works pretty well.
It's unlikely you'll find someone to mix up less than a gallon

Re: TDS3000B calibration
To use some of your words, "you are confusing calibration with adjustment".
Obviously the word Calibration mean different things to different people.
Calibration, at least how we did it at Tek in
