Help. Repaired one of my 2445's. Need to go through Calibration. Went through it other times in past but don't remember this. My calibrator sq wave is not 0.4 usec wide ... it is 0.2 usec wide. It is

I's not TM506/TM5006 related because it is a PSU for 7000 series plug-ins as far as I can tell by looking at the pictures and reading the text. Dave

I wonder if capacitors C611 and/or C612 being open could cause spurious oscillation in V620 leading to all kinds of weird readings from the +500 volt DC supply. Diodes D611 and D612 might even rectify

Hi, I am looking for 2 single wide Tektronix 7K plugin frames. I do not need the pcb but will need all the frame parts with the rear bracket and locking parts. Side panels are not required. I also

OK, I see it now, it is only on the German Evil-bay site, not internationally Looks like a "home modified" TM506 or TM5006. However the location of the "cans" for the elctrolytics do not match TM506,

I believe the issue is that ebay USA and ebay Germany don't share with each other -- so an item number on one site doesn't show up on the other. Stupid, IMHO, but ebay's been doing a lot of stupid

Hi Mark, Hi Dave I can't understand the item is present. Please try this link: http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=160951091504&ssPageName=ADME:X:RTQ:DE:1123#ht_534wt_1186 Gerhard

Doing a search on that item number, Ebay says it's either been removed or it's not available. Is it missing a number or two? Mark

Who knows this Tektronix 6 Unit Power Supply, which is offered at Ebay item: 160951091504 ?

Hello, recently I bought a 7B85. It has most functions working but two problems: bad timebase selector and unstable delta time. This post is about the first problem: the readout was giving wrong

Hi team, A while ago I acquired and fixed a dead 2220 scope and was recently looking for (and found) the Wavestar software to grab waveform data. When I got home I spotted that my scope only has the

Mike Your initial problem sounds like a TRIGGER setting or problem with the trigger..start there and make sure you have the trigger adjusted properly Dave

Hi Ken, The oscillator circuit is not a kind of Baron von Münchhausen. No way that leakage from the HV side could pull the primary input voltage continuously to a higher voltage than the unloaded

I have a probe 6046, which doesn't work. The amplifier is ok, but in the probe the Q224 becomes very hot. All voltages are ok. There is a N-FET Q123 IFC1025, which I can't find anywhere. Who can help

Some (most?) DMMs have MOVs to protect the input of the meter. The spark might have been the MOV trying to save your meter. Get yourself a proper HV probe soon if you like working on this stuff. The

My meter has a DC 1000V range, but I have seen readings today go up to 1900V. I think I figured that the sparking during measurement was due to my bouncing fingertips when approaching the junction to

That makes sense. I knew it wasn't a problem, but couldn't figure out what it was. Thanks!
