Hi Fred, Make a note to yourself - Craig is much smarter than me for several reasons: He knew the answer right away; He was able to describe it in one paragraph; He had a better way to test this with

Any digital scope is a sampling system, so it looks at a waveform, does an average during the sample period, and then ignores the signal to the next sampling period. Pretty much as long as you sample

hello all similiar hi my usual problem with the tektronix 475 voltages as of now: 50v 33 v 50v a reg 67 105-160v 132 + 15v 5.53 5v 3.25 -15v -8..8 -8v -5.12 110v 86.4v What could be the cause? if you

Okay, I think the analog would be more useful possibly in trouble-shooting, but I am so experienced in the TDS3000 series, that I love trouble-shooting with it, plus I know the equipment so well that

They aren't that bad. They can do well. Not really useless, IMHO. Probably is

Craig, Thank you kindly for those detailed instruction, which I have printed out. Perhaps later today, I will follow them and get that puppy cleaned out and generally look inside for cap leakage. Dave

" The 2465B does (should!) have measurement cursors for time and/or amplitude but you have to enable them to see them. Nice dumpster find! " Yea, I found them, before putting it aside this morning to

The knobs don’t have to come off. This is how I do it all the time. I usually take the case off when doing this but the scope needs a front cover which you may not have. But it if you set the face

There is a plastic trim strip on the top of the bezel that snaps off revealing some additional screws. Manuel

Same thing with logic analyzer probes, scope probes, and anything in general. Ran into a bunch of P6201 active probes that were "decommissioned" by cutting of the 40 dollar LEMO connectors. I

Hi Dave, The 2465B does (should!) have measurement cursors for time and/or amplitude but you have to enable them to see them. Not sure the exact buttons that do that but it should be easy enough to

I got a 2465B, 400MHz, while dumpster diving a while back. It seems to work perfect. I do not have a lot of use for an Analog scope, (especially w/o GPIB) but if I decide to sell it on EBAY, or even

Hi Jack, Bert Haskins... he's replied to your topic, see msg reference below. /g/TekScopes/message/152031 Most of his message is quote from previous messages... And his reply is a two

Hi Fred, I glad you asked about this because at times I find this effect quite annoying and at other times it seems like all the curve tracers I have owned (2 x 575s, 1 x 576, 5 x 577s) have displayed

and I do still offer it. For details please refer to < http://www.perdrix.co.uk/SG504Head/index.htm> where you'll find full details of the design, construction and test results. Dave

Alex, Correction: the BNC jack is labled Word Recog Out. Manuel

Alex, If the scope has the optional CTT board then it is very simple with your serial number scope to enable the external frequency input option (1E) by simply moving the coax cable for rear BNC jack

The way to test this is to wire up a cascode arrangement of two transistors, and curve trace that. Since the whole rationale of a cascode is to mitigate the effects of Ccb, the looping should

that?) What receivers do when a company goes bust is make a pile of electronics to sell, and put all cables or anything that looks like a cable, in a large bin and sell that as a single lot. Since a
