Dears, I got a 2715 with battery down. Do you have an idea where I can recover the elusive "271X Flatness Tests" software? Are you so kindly to send me it? Thank you very much in advance for any help

Hi everyone, I’m starting with oscilloscopes and electronics. I got a Tektronix 475 that I would like to repair for my lab. It turns on but unfortunately I have no trace...I tested the voltages.

Interested in a TR502 and cable to pair with my functional 7L13 Also would like original manuals for both Marty KL7AM

Thanks, Tom. This scope has had a bad case of that curse. One tantalum went up in flames and two more smoked pretty significantly. This one just shorted with no glorious demise. There are still

Bad tantalum, C3396, on the OUTPUT SIGNALS board. Replaced C3395 and C3396 and all is working again. Thanks, Barry - N4BUQ

Hi, I just picked up an OT502 E/O Converter TM500 Module in a mainframe of assorted modules, and am looking for a user/service manual for it. There doesn't seem to be much online.. If anyone has a

Thanks, Jean-Paul, Mark, and Tom, The relaxation oscillator I was referring to is the one that makes the neon flash which is comprised of R3019-C3019-DS3019. I was originally writing the above email

Barry, A few things that could cause the fast ticking are: one/both transistors from the 0067 IC to the driver transformer bad, the 9V zener to the 0067 open, the two 1mfd filters from the small

When there is an overload, the PS shuts down and tries again a bit later. Each tick is the sound made by the magnetics as current starts to flow then shuts off. No master oscillator drives the tick

I powered up one of my 7704As which worked fine the last time I used it several months ago. This time it worked for about 30 seconds and stopped with the power supply going into a rapid tick mode

I ground a slight taper on the top of the posts with a tapered Dremel grinding wheel. I vacuumed the cavity and then blew it out at low pressure with an air hose. I remember the HVPS it came out

There are dozens of Dremel tool accessories, and other manufacturers have made accessories which can be used with a Dremel tool. I own 25 grinding accessories for my Dremel tool, mostly aluminum oxide

I may.... or others may... have to remove the HV assembly... and hopefully put it back. If you get a chance... If it came out... why wouldn't it go back? How did you 'grind" the 'posts' ... with a

It's OK I've got this sorted now. I looked through another Tektronix programming manual for a different scope and it describes the OPC operation much better. It's all working fine now :)

Hi I'm currently trying to make some remote measurements (via USB) on a pair of repetitive waveforms using a Tek MSO4104. They occur about once a second and I want to measure the time interval between

I know this is an old discussion, but hopefully it is still active. I finally found the problem to be diode D940 in the high voltage power supply was open. I replaced it with a 2CL2FL diode and the

Forgot to mention that the output of the 1st mixer seems reasonable as far as I can tell. I saw three frequencies at the output of the first mixer: - -43 dBm @ 2.14178 GHz - -40.8 dBm @ 2.1579
