Tektronix 2220 Scope

embrown057 · 9th December 2010, 03:12 AM

I am looking for the service manual for the 2220 scope if any one has a PDF they can send. This is not my primary scope but I do use it a lot for the storage function. The vertical amp is out. I did try EBAM and other sites but no luck on this model. Any help with the manual would be great.

The 2230 manual is here:

http://bama.edebris.com/manuals/tek/2230/

Its basically the same.

That link is for the 2230 not the 2220. The 2220 is a 60mhz and the 2230 is a 100mhz scope. I am not sure the units are exactly the same. I also need the service manual not the user manual. Thanks' any way, I'll keep looking around but the 2220 seems to be a hard one to find in PDF.

My mistake, I did not see you had advised the 2220 and the 2230 were much in the same. I did find the full service manual for the 2230 yesterday. I just got off the phone with Tektronix service and was told that the 2220 and 2230 do share some of the same sub parts but they are not the same. I could not get the details, I realy don't think he had a clue what they were. I'll start on the power supply voltages and go from there. It seems the 2220 and 2230 had a lot of problems with the power supplys. I still would like to find the 2220 service manual if I can.

They are basically the same. believe me:-) Tektronix 22XX series scopes are all pretty similar ie the 2220 and 2230 are almost identical storage scopes (the 2232 is another thing however). The analogue 22XX series are almost the same as each other as well.

Its funny you mention power supply voltages as I found my 2236 was very picky about voltages, particularly the 8.6V rail if I remember corectly. It was a few years ago now.

If it is a PS problem I helped a guy on the Tek scopes forum do a full on fault find on his only to find it was the trippler. This is clearly not your problem so if it is PS trouble I can find the posts and send them to you. Its a fairly thorough work through of the 22XX series PS.

I believe the only important differences are a few details in the vertical amps concerning bandwidth, and perhaps a higher sweep rate in the 100MHz version, but these differences will be small, at least until you find a problem in a circuit that *is* different. I think the power supplies are all the same in that series, which is why they were economical.

I tried looking all my places, plus a few new ones no luck. Just wondering if you contacted tektronix. Sometimes if your nice enough you can talk them out of the pdf file. Its worth a shot.

No, no such luck for this scope. I spent a few hours on it today and the problem is in the power supply. There no secondays voltages. I found an N ch fet that was shorted "IRF730" but so fan nothing else. I could realy use that manual or at least the 2230 service manual. The 2230 manual I found was just the operation one. I will keep looking.
