Tektronix 2465, 2465A, or 2465B
Hello Ross, I have a 2565A that I am thinking of selling. It hasn't been re-capped (no issues there) but has had a new battery recently installed, and I have been through the recalibration procedure.

Gary, I deleted the email where you posted the part number you are trying to find, but I have a few 152-0125-01, 4.7 ma. tunnels; they are replacements for 1N3717 and TD-3A, I am told. I used them for

Risetime calculator (in tekwiki)
Never mind, then-came-the-dawn; three different scales to get from 0 to 20 and I assume that proportionally you can try to put your values as close to center dial as possible for greater accuracy by u

If you look at the dials, each is calibrated 0 thru 10. Then there are numbers in red, 0 -20 and another series 0-5. Just trying to figure out what the different scales mean in the context of rise tim

Remote CSA803 / HP1180x programming (yet again)
It must have been "Recommended Standard," because I had (have somewhere?) a book that had 132 or so versions of the RS-232 "standard" interface. That's a lot of versions of a so-called standard! Gerry

it's easy to add an external battery at 2465B NVRAM
Hello Joseph, Did you remove the internal battery before / after adding the external battery? The Test 04 fail probably means your calibration data is corrupt, and once you have replaced the NVRAM, yo

One of the calibration procedures produces those series of dots when setting the vertical limits, if I remember correctly. It would appear that whatever initiates that procedure is somehow "stuck on."
