Re: Calibrating 2465B
Jim WIlliams wrote at least one application note where he presents a pulse generator with ~350 ps rise times. I took a quick look through my collection of Linear Technology application notes and found

Tek 453
I have a few Tex 453 scopes. Two are oddballs in that they are MOD0703K so they differ a bit from the manuals available, although folks here pinted me at a doc that lists changes. The biggest

TDS420/460 Schematics
Although not 100% accurate schematics for the TDS400 series have been posted to the files section of this group as well as TekWiki. They were scanned from "C" and "D" size engineering drawings and

Re: Calibrating 2465B
(Home made) tunnel diode generators obviously need very careful physical layout with minimal dimensions and preferably, checking and adjusting with a fast (sampling) 'scope. In my experience, S-52's

If you have CTT option the cal requires a precise 50% DC precise frequency and level. If no CTT option ignore Jon

Re: 2465B focus at high brightness
Re-reading your message: Are you saying that when you need to use a high Intensity setting to achieve reasonable trace brightness because of low trace duty cycle/fastest hor. speeds, readout loses

Re: 2465B focus at high brightness
Are you using your 'scope to light the room? Why else would you use such high intensity? None of my (40+) analog Tek 'scopes fully keeps focus at between 75 en 100% CW of Intensity. You say you have

FlukeView for Fluke 105B Scopmeter Series II
Hi! I have an old Fluke 105B Scopmeter Series II. I have its serial cable, but I have the chance to access its floppy disk with the FlukeView app. Is there anybody who can help me with the app or a

Re: Calibrating 2465B
I wonder if a Leo Bodnar pulse generator would work. IIRC, it can produce pulses with 350 ps rise times. DaveD KC0WJN [email protected]> wrote:

Re: Calibrating 2465B
Each Cal group is self contained, as long as it completes with no errors, the CAL for that procedure is saved to NV Ram. Transient and CTT are most critical CAL, but PS,Hor and Vert are easily done

Re: Calibrating 2465B
This is all necessary as the original DS1225 had parity errors (it was datecode '96). I don't know of anyone locally who has the right Tek test gear so it's either try with what I have or leave the

Re: Calibrating 2465B
Hi Keith, I saw Siggi's reply just after I sent mine. He has a lot of experience with 2465 'scopes and always makes a lot of sense in what he says. As an example, he may well be right re. transient

Re: Calibrating 2465B
Hey Keith, I calibrated the CRT, timing, vertical and the triggers on my 2467 using a TG501 and a PG506. I didn't touch the transient response calibration, but I don't think the PG506 is fast enough

Re: Calibrating 2465B
Thanks Raymond, yes the fast edge rate is a problem, the 8112 is about 5nS min. However... I do have the Tek fast pulse PCB that is used in a PG506, I believe that has < 1nS edges and could be

Re: Calibrating 2465B
I¡¯d be *very* surprised: You need a relatively low frequency (1MHz or so) square wave with an edge speed << 1ns for risetime/BW check and adjustment and low-and high-frequency pulses (up to 1GHz)

Calibrating 2465B
Has anyone managed to calibrate a 2465B without using the Tek specific test gear (PG506, TG501)? I have an HP8112A pulse generator and an HP33120 function generator, can they be used instead? -
