Trace rotation can change if you bang the scope around.... But more likely is that "calibrated and tested" means that it was calibrated and tested at some point in its life. I would expect an A to

Dennis- I have done similar and See, no good deed goes unpunished. Do enjoy the journey...you were able too see and old friend. You are greatly appreciated for all you do. May you and your family have

C'mon Dennis, I'd love to have my book soon but please wait until things won't be as busy! You may have to wait half a day until it's your turn, only to be sent away because they're too

My original idea if I got orders for 10 to 15 of Peter Keller's CRT books was to have him ship them to me and I would mail them out to the individuals who ordered them. (Please feel free to form a

Any of the above (whether 350 or 400) should be better than my 300 MHz 2465 that has a rise time measured at 0.91 nsec.

two things that you'll lose over the chinese scopes that you mentioned are size/weight and record length. These TDS5000 series are pretty bulky and "loud" (like TDS7000 I assume) and the record length

I won't comment, for fear of price increases Price just came back down, unless a PSU issue. Raymond

A lot can happen in 6 days on Ebay. My guess is it won't go for less than 1000.00USD... which is a lot more than a Chinese manufactured oscilloscope, sold by a Chinese company.

I second that but did he post a link? i dont think so. He has a good and valid question

Jeff, Just some thoughts from looking at the schematics: Can you verify the effect of X-Y Time/Div setting on the emitter of Q1338? The entire circuitry around Q1338: wasn't your original issue with

I not saying someone can't, or shouldn't ... but, I wish people wouldn't post links to Tek stuff for sale on Ebay... it probably causes someone I'd like to pay more... and someone I wouldn't like to

I love this! As has been written before, "calibrating" in its pure sense means nothing more than comparing against something considered a standard. Without specifying the results, i.e. deviations, it

I've found the automatic parametric tests in this family inaccurate and varying in their results. Of course, rise time measured depends on overshoot. Accepting 3% - 5% overshoot during rise time

Jeff, That's very interesting, I had no idea that the local magnetic field would have such an impact. But that completely makes sense why its an operator control. Thanks for that info. I will say

Gravity is a factor. Placing it vertically/horizontally makes a difference. Magnetism would be a very important factor were it not for the mu-metal shield around the CRT. Whether it deserves to be

Using Leo Bodnar's pulse generator, my 2465 (no A or B) measures 0.91 nsec. So there seems to be something not right with your 2465A. It should be better than my 2465. And your 2467 should certainly

To Jeff: The TEK CRTs have a fine MuMetal CoNetic shield and are NOT affected by earht or other ext mag fiedls of normal gauss level. To Eric: >>trace rotation was wayyyy off and the geometry

The 546A used a tiny current transformer (shaped and shielded to be z-axis directed?) This Bee thing... They claim to be using a Honeywell Z-axis anisotropic magnetostritive sensor (not a coil based

Eric wrote: My impression (please correct me if I'm wrong) is that trace rotation is a correction for the local magnetic field, which is why it is an operator control. If the scope was calibrated (or

"The wet hermetic variety, if it even existed then..." Regarding the existence and use of "hermetically sealed, wet tantalum capacitors...I suppose if one contextualizes the discussion in terms of
