Hi Friends (and I don't say this lightly) I'm a noob at oscilloscopes as they have always been out of my reach to purchase. I have worked many years and mostly depended on my trusty Multimeter to get

Well, you can take the Bayesian approach... a subjective interpretation of probability models, with feedback training... it's as legit as the frequency approach. But anyway... back to Tek. Some great

As a single data point, I've killed [1] my 455 and resurrected a 2440.? So I guess my net phosphor footprint is zero, for now. [1] well, I expect it's repairable, but HV scares me, as it should. --

I have hesitated to mention this as a possible approach to the filter caps in the 475 because: 1. I don't know for sure whether the layouts between the 465 and 475 are identical 2. The design is,

Thanks Chuck, Jamie, Larry and others for your posts on this. As a relative "beginner" in scope repair I could not say enough good things about the encouragement and wisdom available in this mailing

Bruce, I treat tantalums like I treat people - assume they have good intentions unless I learn otherwise.? If you remove lots of them without reasonable suspicion then you'll probably do more damage

I will put in my 2 cents worth here.? I have a 465, and it had been in storage for about 2 years.? It wasn't working when I got it out to use.? Have owned it for about 7 years using in my trouble

Hi John, I have to set the record straight. Dennis did not jump on me for describing a way of using an oscilloscope to measure ESR. Quite the opposite, he even tried to help with my poorly received

Does anyone have any idea, statistically, of how many scopes die from beginners trying to repair them verses those that die to tube harvesters or relatives who have no interest in "Bob's" old scopes

Hi Roy, I guess the first thing is that tektronix made these scopes to be reparable by their customers. That is why they made available such detailed manuals for their scopes. I am pretty sure they

In answer to your question, ANY time you bring in fresh blood, it's better for everyone. Every time. No exceptions. A rising tide floats all boats. Right now, Harley Davidson is facing 'massive

Thank you for this information. I was trying to use a Parallax USB to serial converter, I think the ASIC direct drives the pins. I'll look at trying to add a buffer IC for more drive on the TX pin. Or

I have some things to add given that I was in a similar position recently but with a 485. Go glacerly slow. There are some parts in these wonderful instruments that you will not be able to replace if

Roy I have to add to this one. As 3 years ago I did JUST that. I had a soldering Iron and a power supply on the bench. And started to dive deeper in to electronics. I made the mistake of taking on a
