Comments inline... You're right! page <4> is missing! The doc looked pretty good to me when I first looked at it. ;) That being said, my dead-tree version that is truly complete has the following

The cheap probes seem to be as good as the expensive ones, in my experience.? I don't give my probes daily use so they are my best option. I also fail to see how being cheap implies poor

While in the military, I was responsible for repairing a computer. We ordered a set of scope probes and got a clone of a Tektronix probe. While looking at a 50 MHz clock on the scope, the waveform

I've never used them but the cheap probes are available up to several hundred MHz (250-300?) for a bit more money. Has anyone tried them and know how good or bad they are above 100 MHz. It may be more

You might eventually find electrical limitations (frequency response, reflections, ringing, etc.) but for moderate frequency work where they are satisfactory, they are saving wear and tear on you good

You don't actually say what your complaint is but it obviously upset you. 'nuff said from me about that. However for sending money from here (Australia) internationally Paypal is the only economical

I have heard that there are some instructions and maybe a photo of how to fabricate an HV multiplier here somewhere. 10 minutes of searching has come up empty. Can any one point me to a procedure for

Hi Richard, I have a selection of 57X curve tracers including this model of 577, and I would guess there is nothing wrong with that CRT. My experience has been that curve tracers do not get used much,

The Generator arrive today from USA to my Argentine door!!! . Unfortunately not work fine. Rt=1,67nS (instead 300pS) Width pulse= 5,84nS (wave exponential decay instead rectangular pulse) Max out=

Tek has a Primer about probes on their web site. I believe it's "ABC's of Probes" or "XYZ's of Probes" There's probably a copy in the Yahoo archives too. ? HankC, Boston WA1HOS

I believe that display section is the same as the storage section of a 5103/D11. I have one of those & mine adjusted to a uniform flood. I'd be willing to bet the CRT is OK & can be adjusted per the

I have some similar 100 MHz x1/x10 switchable probes for my various 100 MHz oscilloscopes and they work and test fine. I have some faster 250 MHz x10 probes for my 2440 which is 300 MHz and they test

Good to know. Thanks. That means "leave it in". DaveD

The screw "plug" grounds the metal frame of the plugin to the chassis of the TM500 Power Module as well as aligning it.

This is hand made by one of our own forum members, Jerry Massengale.

I have to say that I disagree with this. I think that the main difference between Tek probes and cheap ones is frequency response flatness and consistency from probe to probe. Of course more expensive

Richard, This is the split screen storage version of the 577, and unfortunately the pictures do not give information on the health of the instrument. Both photos were ta

It is interesting that the seller of this 577 has it listed as "Used", which by definition says that it "functions as intended", but then has a huge disclaimer at the bottom of the auction listing

I just ran across this interesting implementation of extenders for Tektronix 7000-series 'scopes. Made by Maytek. Has anyone ever used these? Ebay item #290878562763 DaveD

My 466 (storage oscilloscope) is also certainly not even when it's flooded, although it's brighter in the middle than the edges. It still works just fine, even with the uneven flood. I would say that
