Tek 2440 - Old School Digitizing Storage Scope
Tektronix's 2440 DSO was introduced in 1988 before the advent of surface mount devices and LCD/LED screens, so its (larger than today's) size and weight reflects 1988 state of the art. 2440 was envisioned as the storage counterpart to the analog 2465B While speed, convenience, and connectivity have improved since 1988, quality and durability have not. Many of today's DSOs are fluff boxes that will become instant e-waste first time they break, whereas 2440s not only have stood the test of time, but are still repairable when they break (one of the great advantages of thru-hole technology and availability of published schematics). Production of these ended circa 1993 by which time vast numbers were sold (great news for finding discontinued spare parts units). Tek introduced the TDS 350, 360, ...

Production of these ended circa 1993 by which time vast numbers were sold (great news for finding discontinued spare parts units). Tek introduced the TDS 350, 360, 380 as suggested replacements in the mid 90s, but those are the fluffy replacements. By the late 90s, Tek introduced the TDS 3032 3034,.. as suggested replacements, also fluffy, but much smaller. All of these belong to the new non-repairable era. When you buy one on ebay, keep in mind that most 2440s may be spare parts donors, and ones in perfect shape are rarer and generally found from those with a reputation for specializing in them. If you have the means to pay considerably more for a newer TDS3000series, keep in mind it may not be repairable if/when it ever fails.

This is a competent though aging scope with 300Mhz Bandwidth and 500Ms, a real gem no doubt in its day. I has many features including measuring cursors and pass fail checks for QA testing. But there are many out there that are failing although. One fault is the NVRAM error check at boot, most likely to be a flat memory battery. This will usually result in a full recalibration of all the scopes settings. The other more serious fault is the CCD (7000) failure that should shew up in the boot check if there's a problem. Because these scopes use equivalent time processing (build up) the higher frequencies, CCD,s are used to store and process the data before being sent to the display. They run very hot and many have failed due to age and cooling issues. A quick test will confirm any ...

They run very hot and many have failed due to age and cooling issues. A quick test will confirm any problems. Set the scope to display both channels and trigger from line. Increase the timebase to 50us/Div and set trigger to line. You should the two traces of both channels when positioned correctly on the screen. Moving the lines with the positioning control should not produce any spikes on the waveform is moved up or down the screen, If there are, of the trace won't shift the CCD on that channel is more than likely dead. Parts are like hens teeth and repairs if parts can be found are costly as a full hardware recal takes a long time! Hope this is of help to anyone out there thinking they have found a bargain.

Tek 2440 is Acceptable
I collect electronic equipment and am a self taught electronics's experimenter. I found the menu system of the 2440 somewhat cumbersome but after about a day of going through the different menus I was able to master it. I think if the scope is not used daily the menu system will become an issue. This scope has more features than I will ever use. The auto set up feature is a real time saver and works very well. I do however prefer the trace pattern of an analog scope vs. a digital. The analog seems to show much more detail in the wave pattern. So far I would say my first digital storage scope purchase is acceptable.I collect electronic equipment and am a self taught electronics's experimenter.

A top of the line oscilloscope for bargain prices, I can afford....
I am very pleased with this 2440 Storage scope. I also have a Tekmate 2402 I want to incorporate with it. The 2440 is a joy to use, and documentation is readily available. I use ths for my hobby work basic repair and troubleshooting electronics. If anyone is on the fence hop over and get one. I especially like the ease of use and setup features, waveform storage is nice as well. This is my first venture with a Digital Storage scope and a very pleasent for sure....I am very pleased with this 2440 Storage scope. I also have a Tekmate 2402 I want to incorporate with it.

works better than expected.
Works great, it's usable bandwidth is higher than rated, I've gotten good results to 700 MHz--the waveform may be a bit jagged above 300 MHz but it measures the frequency and voltage level accurate enough for troubleshooting, my new DSO doesn't go beyond the rated 200 MHz.
