TEK 2432A is a DSO from the repairable era (made same time as 2465B) and you can think of it as a 2440 with half the sampling rate which halves its single-shot capture speed capability. Scope is in nice shape for its age (30y). At BIN, I will send you this correctly working, freshly calibrated Tek 2432A, serial # B010295 (made c 1990, does not have option5 or any other, accumulated 31Khrs), with 14 days guaranty. If you offer more, I can add some extras to make yours better.Please specify along with your offer which (if any) add-ons you're asking for. Lithium battery (backing NVRAMs) was replaced by me. 1st photo shows passing selftests. 2nd shows 1KHz 1Vpp square wave from my PG506 feeding both channels, and displaying correctly. 3rd shows a 5MHz 1Vpp sine wave from my SG503 displayed correctly on both channels. 4th shows a 50MHz 1Vpp sine. Before digital storage scopes evolved into small lunchbox sized surface mount populated fluff boxes in the late 90s, there were digitizing scopes such as the Tektronix 2440 that actually contained normal size parts that can be worked on with human sized fingers. So unlike with newer DSOs, this item does can be fixed to component level, rather than just board level. While today's DSOs are smaller, can usually sample faster, and can have USB communication (which is more convenient than GPIB), their newer build quality seems flimsier, and their complexity is so great that their schematics are kept secret, thus discouraging/thwarting repair efforts. Tek labels the 2432A as 300MHz / 250 Megasamples/second.
Just as analog scopes should not be used close to their upper bandwidth limit, digitizing scopes carry the same caveat, even more so... It is best recommended for use at under 100MHz. Like all Tek 24__ digitizing scopes, this is a fulltime digitizing scope, meaning there is no fallback analog mode as in Tek 468, an early slower combiscope. Whereas a non-storage scope can only display what happens after triggering, a digital storage scope can also display what happens before triggering, and this is its main advantage it's like a time machine.
You can think of it as an endless loop recorder (like a cockpit voice recorder of an airplane) and you can look back any part of the loop you haven't yet re-recorded over. The length of the loop is 1024 recording points. A point can be as long as 50mS at the slowest sweep speed, or as short as 2nS at the faster sweep speeds.The vertical scale (8cm on screen, 2 more cm offscreen) can similarly be thought of having 256 points. Ask questions (in English or French). It's a good way to discuss your exact needs, match you with correct package, options, accessories... It's not trivially simple: instead of usual 2 terminals, most often, there are 56 soldered pins in the form of two 28 pin ICs; not an end-user's task. I have no control over that.
I leave feedback after you do. Please let me know if you plan to use it at 230V rather than at 115V.
