What a shame that a few thin plastic pieces sidelines such a nice instrument. Thanks, Barry - N4BUQ

Um, perhaps you mean green soldermask.? Soldermask is most often green in color, although red, blue, and purple are becoming more popular lately.? Most PCB fab shops would rather do everything the

Gudjon, I’ll be interested to see how you go - as far as I can see, the switches are tucked well in under the attenuator pcb and accessing the rear of them would require quite some dexterity! I’ll

That's really good, Tom! I'm going to have to remember that one. Nice explanation as well, Ed. Thanks. Jim Ford

The side covers have never been printed successfully (to my knowledge); they are thin, delicate and the retention features are too small for accurate reproduction in a printer.? They provide the

I don't see what all the fuss is about in this offshoot of the original thread (2465 calibration). Disregarding the semantics, and "exact" definitions of things, I view DC just as valid as a "probe

A hobby propeller collet can be installed in the fan. Search groups.io pictures section for: "2465 fan collet repair, 9 pictures" ? Laura ?

0 VDC = A Sin(wt) VAC, where w = 2 x pi x f, for all t, and only when f = 0 which is the type of stuff we often argue about. -- Roy Thistle

To be clearer, if not somewhat pedantic, there are fields everywhere: electromagnetic, gravitational, strong weak. Although general relativity shows light conforms to the curvature of space-time,

Try the vintageTek Museum They were nice enough to sell me some used ones.

The side covers on the plugin sockets (P/N 200-0950-00) in my "new" scope are in pretty bad condition. I've read where folks have tried 3D printing those several years ago but not sure how that worked

Hi all Roman: I am pretty sure that by removing the trim capacitors, which is easy, you can disassemble and clean all the switches and assemble them again. I will try this as soon as I get some time

Does anyone know how and or where I can pickup option 2.

Another possible fix is to use AC Termination. This is a Series connected R-C placed in Parallel across the Cable Destination Load. Since you have a fixed frequency (1kHz), and a constant Impedance on

Some responses. Do you have a lot of Overshoot or Undershoot on the waveforms you are supplying it? On the other scope, what is the Rise and Fall Time? If it is too fast, since the Impedance is High,

Hello Everyone, I have a Tek 2225 scope which has an oddity which im trying to fault find. Overall the scope works fine, however, when set to 0.05uS/Div there is a clear ringing on the display. It

Albert, I tried it later and no I did not notice any difference at any magnified setting. It did however prove to me that thing is flying fast. Jeff -- Jeffeelcr

That makes sense. Oh, and I discovered that in Cal 02, vertical calibration, the 2465 is NOT put into 50 Ohm DC input mode. It is in high impedance mode. So my voltages are not being divided by 2. So
