Hi, On the 2440 and its sibling DSOs, the scope can be configured to do various things on pressing the probe button, like saving the waveform or switching between predefined configuration settings. Th

Hi Dennis, Yes, you are right. 3 out of 4 batteries still work. The fourth.one had zero volts. So I was able to verify that the plugin works. Ch1 was good ant interestingly Ch 2 sort of worked also. I

Hi Rick, I'm in a similar situation, I'm going with LEDs. It is a very useful plugin. I got a lot of useful advice from this list on it. I have already selected the LEDs from my drawer of parts, but c

Hi, Yes, I have a 5440, it has readout. I was actually wondering why Tek left out the readout from the 5s14n. Was it for compatibility with the low speed 5000 mainframes? Or was it some business decis

Hi, I'm working on a hobby project to enable readout for the 5S14N. As far as I know after a lot of reading on manuals that the 7000 and 5000 series readout is basically the same. I know that the 7S14

Hi, Robin Renzetti (Robrenz) did an extreme restoration on a 7603, he documented it on eevblog: https://www.eevblog.com/forum/testgear/tek-7603-scope-w-7a18-amp-7b53a-timebase-restoration/msg172135/#m

Hi, This could be a lot of things. But the first thing is to check the power supplies. If you don't have the service manual, first get it from for example TekWiki: http://w140.com/tekwiki/wiki/2430 Ch

Hi, How on earth did they lose the package? Szabolcs Martin Whybrow <martin@...> ezt írta (időpont: 2020. szept. 22., K, 10:49):

Hi, I would first check the power supply. I'm not a big fan of "the universal internet method of fixing everything", that is indiscriminately recapping stuff, but in the case of the 24xx family DSOs,

Hi, I don't think this is possible on the 2440. This scope closely mimics the controls of the analog scopes, but inside it works differently. Both channels are acquired simultaneously and constantly a

Hi, Thanks, it is good to know that longer wires make such a difference in this application. Although maybe that could be solved by placing a capacitor right next to the board. I'll have to experiment

Hi, I managed to get a 5S14n on eBay for my 5440, I reckon it is somewhat of a rare item. While it is still being shipped, I'm preparing for what I will need to do. So far I've already read through th

Hi, I'll be very much interested in it. I also have a recently resurrected 2021. Szabolcs Martin Hodge <mhodge@...> ezt írta (időpont: 2020. aug. 4., K, 4:32):

Hi Ram, Wow! This is a very exciting project and shows really cool results. Unfortunately this means that I will need look around and buy a 2465 so now I can be sure that u800 problem wont hit me :-)

Hi, I'm not experienced in 3D printing, but would it be possible to have this in two parts? A frond and a back part printed and then glued together by their flat side. This would make it possible to c

Hi, 5000 plugins do fit and work in the 5400. But not the other way around. Of course the bandwidth is limited by the plugin and no readout. I have some 5000 series plugin such as the 5a14 or the 5ct1

Hi, Yes, you need to use the Dallas nvram, with built in battery. I suppose it would be possible to restore the external battery but there are some components that would need to be populated. However,

Hi, Remove, clean an reseat the hybrid circuits. Look at the details in the extended diagnostics. If it is one channel that fails, you can swap the ICs to find if any of them id bad. Although I'm not

Hi, First see what the extended diagnostics says. Then the usual suspects: Power supply voltages and ripple. Remove the hybrids from their socket, clean the contacts a reseat then. If that does not he
