I have one of these 7A18 with the offset pot in place of the trace identify button. But mine has an "option 6" label on the top. It also has an additional position on the input switch. Instead of the

John: I have 4 of these P6201 probes and in all R298 runs HOT! When I have the covers off of the Amplifier Box for adjusting and every time I touch R298 accidentally I jump a foot because of the temp

I doubt that you will ever find a EP53A. Look for a TU-7 which is the EP53A and a pulser combined to cal the 535/545 scopes. Actually the TU-7 works for most 500 series scopes. How many plugins do you

Dave: After researching the source of this 7104 manual FEB 1989 I see that I did buy it from QSERVICE Nikolaos Kapetanakis for $US 9.49. So I don't feel good at all in sending this PDF to anyone and/o

Dennis: I know you are not looking for a PDF but I have a scan of a 7104 manual dated "First Printing NOV 1978, Revised FEB 1989". In the "MANUAL CHANGE INFORMATION" at the rear of the manual the late

I had the same problem about 6 months ago. I had 4 7A26 plugins that I had picked up a few years ago but didn't have the time to check out and calibrate. I just couldn't believe when I started on the

The 013-0138-01 is the correct adapter you want, as stated in other messages. But as I remember this one came with another label which was C B E that allowed you to rewire this adapter to this configu

I have an Agilent/Keysight 1733C LCR meter. I has measurement frequencies of 100Hz, 120Hz, 1Khz, 10Khz and 100Khz. It also can be set to measure C with either parallel or series R. I of course used pa

One quick thought. Check the 1 megohm input resistor R-39. That one could be open. Also check your calibrator square wave with the X10 probe. It is probably not square anymore because the 1 meg isn't

Gary: I have downloaded it twice and it opens fine for me. I see others have also downloaded it with no problems. Not too sure what is happening for you. Bill

I just uploaded a pdf of the Tektronix 067-0538-00 input normalizer manual. From the "calibration" instructions, Tek says to measure the input capacitance of a 20pfd input with the scope turned on. Th

Chris: I still have the 155-0022-00 in the original package that I ordered from TEK 20 years ago. If you live in the US or Canada I can put it into a padded envelope and send it to you. It sure isn't

I believe that U510 is P/N 155-022 rather than the 156-022 that you have quoted. At any rate did you notice that both the A3 Trigger Selector and A4 Vertical Interface boards, U324 and U214, have the

Suddenly the "Search" function is working again. I did nothing between yesterday and today. Maybe the people at Yahoo did know something was wrong and finally fixed it. Thanks for the help. Bill

Thanks for the answer. I am using Mozilla Firefox so the problem probably is with Yahoo. For others, I am talking about the "Search" function that is to the right of the "Message #" that takes you to

Has anyone observed that the "Search" function at the top of the "Messages" page isn't working and hasn't been for at least a week or more. I have used it before and it was working. It doesn't work on

I have some of these lamps direct from Tektronix, of course years ago, for the Tek 576. The ones I have are marked "Dialco" and have a part number of 507-3914. They are 14 volt at 80 ma. It looks like
