Of course, primary calibration labs at NIST (US), NPL (UK) and NRC (Canada) all function nicely. The Canadian NRC Metrology labs may have a faster turn-around time and somewhat of a lower cost( CDN$

Hey Andy I offered to make a short video on it and upload it to you tube. I have 2 different filters on the 7603's one is the ND the other is the clear. I will be uploading some pictures on a 7704A

If S/W was a supplier and you have the color name, they will most likely be able to look it up. You might also want to check with one of their industrial branches. I recently had to get some Sunbelt

Eric, I have to say that the photos you uploaded make me want to swap out the lamps on my 7904. Normally, I'm a reasonable adherent to "it ain't (that) broke, don't fix it", but your results look

5 standard cells, I think Leeds and Northrop did a set in a very nice Oak box. Seriously my final standard was a a 3458A with a 3245A, what a set of equipment. Regards, Stephen Hanselman Datagate

Ingo: No unfortunately. Karin

Somewhere in the archives is a post that has the particular color formula for Tektronix paint. DaveD

Dennis: Have you tried this with a pulse that has a slower rising edge, such as the square wave or pulse out of a function generator? Does it do the same thing with a falling edge pulse, no 150MHz

I have some of that paint and it came from Stan Griffiths. The paint color is Williamsburg Blue. Stan had that matched to Tek scopes. I'm not sure if the Williamsburg Blue is a stock Sherwin

I agree, a fluke 515A is an excellent calibrator (if working and calibrated) for any home lab, maybe ditch the batteries, they are nothing but trouble. They show up regularly, but again, the issue is

The phone number, according to a thread on EEVblog, goes to Sherwin Williams, who are still in business. I'm going to go to a Sherwin Williams store to see if they can get some shipped to the store

It is always great to hear when someone gets something working again. Mark

I'm going to go by a Sherwin Williams store and see what they can offer me to match the 308 front cover (the most portable sample of Tek Blue that I have to hand). What I'd really like is to be able

I used this ( Krylon® ColorMaster™ Paint + Primer, Gloss, Bahama Sea, 340g ) on a case for a 2235 and it turned out pretty good. Not a exact match thou.

We have been busy adding lots of support parts, and lowering the cost of ones tha thave been sitting a while, . Alos, I had many requests for more variable AC power supplies and Variacs like the

I'd be wary of any aerosol spray cans that are very old. The propellant tends to leak out over the years. The way to test it is to spray some out, but then once that's done, it's likely to leak

YEAH! Excellent work, Karin. I am totally psyched that your 7934 is once again amongst the living. DaveD

Hi Jeff, I also assume that it is a batch date. I just looked at the two cans I have, and there's no such information on those particular samples. -- Cheers, Tom -- Prof. Thomas H. Lee Allen Ctr.,

How do you know you see those colors better?

I'm just guessing, but since both trace and readout intensity is affected, doesn't that implicate the HV supply? If there were a single failed component I would expect that only one or the other
