Do you mean 1ms or 10ms? The video can be interpreted as 10ms and slower. I would start by looking at anything and everything connected to the timebase selection control, including - timebase switch

No, but field service for many relatively recent instruments is obsolete, as it requires instruments generally not available to those who wish to perform field service. That is why I use a number of

Hi all, I've receveid an help request from a friend of mine. It owns a decent 475 that exhibits this strange behavior with the main sweep ("A"). with trigger in AUTO, the waveform from the calibrator

Hi evdsp39, The manual in tekwiki has also plenty of block diagrams but no circuit diagrams. (has Tektronix decided that circuit diagrams are obsolete??) Did you get any response from the poster

This is a pretty long feed that tarted back in January. Lots of good info thur-out this. I finally got back started again with all the sit at home time. The 2465B s/n B010817 I got a correct

Thank you Victor for the info and reply! out of curiosity, I found that mouser carries the internal battery but from what I've read so far they seem bo last quite a long time. Should I just check and

Yes USD.Bill

Hi Bill: A fair offer where? (Some said 150.00... but... is that USD?... I assume it is.. but, assumptions often make of me something I don't want to be!) Best regards and wishes. Roy

Hi, Remove, clean an reseat the hybrid circuits. Look at the details in the extended diagnostics. If it is one channel that fails, you can swap the ICs to find if any of them id bad. Although I'm not

Thanks Matthew 73 Richard W4MCD

I have 11 of them (if not more) in my library. I am looking at "103 Projects for the Electronics Experimenters", by TAB BOOKS Inc, Blue Ridge Summit, PA 17212, first edition June 1981. Other include

Hi all,I am new in this forum and I hope that I can find a solution to my problem.I have a 2782  spectrum analyzer whom the focus, astigmatism and intensity are not operating at all.I have the 2782

I recently picked up a Tektronix 2430A for next to nothing because it had failures on the self test. Most of these failures were caused by a dead backup battery. I found a suitable replacement and

i own 4 2235A and the military version as well and they are a great analog scope. Mine came off Ebay after negotiating each one. i won't go above $200 on them myself. I did pay 400 for a brand new

Hello: I received 3 P6131 probes for the cost of shipping. The problem is the probes came with the collar but no ground lead. I need: 1) 3 Ground leads that connects to the collar. 2) 3 probe tips

I would guess $100 to $150 but for myself, I would hold out for a 2232. The 2232 does a lot more for about the same space and cost.  Bert >

All, Update on the group purchase. As of this morning, we have deposits for 7 kits, plus I'm planning to order 2 for my own use, making 9 total. To avoid spamming the list with daily status updates,

In my search for an Oscilloscope I ran across a local 2235A in excellent cosmetic condition and it produces a signal on both channels. Looks like it had a very easy life. Doesn't even have

First question: are all the CRT voltages about right? Second question: are the "low voltage" z-modulation waveforms correct? It is simpler to inspect grid waveforms if you have a suitable probe,
