Hi Holger, Nice work, I'm always pleased to see new gadgets bridge the gap between the modern and the vintage. I invested effort into writing software that lets you connect the 7854 to the modern PC

Looks very nice Holger. For the user it's likely far more convenient than your GPIB interface for the DPO. Success, Albert

“Nyquist” applies to continuous sinewave-like waveforms only, not single shots. That’s why ‘scopes don’t show any reasonably usable waveforms even when complying, not even at

Hi agree , he should be here Brian (UK)

Chuck has been wrongly banned! I hope for his return!

I tapped a razor blade between the two halves at the glue joint and it came apart easily. Maybe it was just a fluke, will know when I try another one. Chuck -- See Early TV at: www.myvintagetv.com

Hi everybody! I'm currently in the process of developing a USB interface for the Tektronix DPO (aka P7001). And I'm very happy to tell that my first prototype is now working. I've added some images to

thank You Mark, My bad about +15V, is not regulated rail, but unregulated +15V.., shows 22V. Waveform 161 indicate, thats ok, (21-21.8V).. Others tips i will check soon ..

I'm still quite a way from a successful wind and the only transformers for which I have winding data are the 545B/546/547, 549 and 556. Watch this space! Morris

TekWIki says that the 2440 is 300MHz (analog bandwidth) with 500 MSa/s (digital sampling rate). It doesn't say what the single shot bandwidth is, but it has to be less than 250 MHz just based on

Hello Morris, I’d also like some “restoration” bits of that unit is (unfortunately) going to get scrapped. I’d be happy to contribute to the postage if the chosen bits could be bulk shipped.

Which 500 series scope? I need HV transformers for my Curve Tracers.

Hi all, It's been a few years since I last disassembled a 500 series HV transformer core. It's a ferrite double "E" with a small air gap in the middle leg and the two outer legs glued together. I seem

If you're parting it out and don't mind posting stuff to Australia i wouldn't mind a few bits. I'd like the HV transformer and the "Graham Cracker" non inductive resistors from the final stage of the

Do any of you own an 1180xx/CSA803x? It takes 3 V to blow a sampling head! I paid Tektronix (chipxs) $250 for my SD-24 and $750 for my SD-32 prototype. The SD-32 is labeled SD-30 and was listed by Tek

I thought the published spec on the 2440 was 200Mhz, 300Mhz in repet mode. Was this in repet mode? Jeff

I have a TLA704 anlyser which I've repaired and upgraded, but it's missing the front cover and accessory pouch; has anyone got either of these they can ship to the UK? The part numbers are: Accessory

to bad I live in Wi.

Hi Dave, As far as I can see the way how R90 functions is not described at all in the manual. The (I would say disturbing) leakage by Q90 (and possibly also by some reverse biased diode) ill have been

Another thing about wills -- in Texas at least, they are good for four years, then need an update.
