Hi to All, Still looking for this Module User Manual. The only item I could find isn't available for those outside the US. Anybody? Greetings, Egge Siert

Hi Siggi, The PG506 specs mention delay time 18 ns between trigger out and Hi Ampl pulse out. I don' know of course how much delay time is added by your home made pulse generator. But if you didn't

Hi Siggi, I tried my very early PG506 with a 7904 / 7A29 or 7A16p / 7B92A. I can't measure any jitter between the trigger output and the fast rise outputs at the 50-100psec level. The rise time of the

Hey y'all, I have a little shop-made TD pulser I drive off my PG506 high ampl output. I also now have a 7S12 with an S-4 and an S-53, so I figured I'd be able to look at the rise of my pulser, as the

Hello Russ, My comments just after yours, below... Rgrds, Fabio Hmmm, "Small blue chicle", to me, this shape resembles very well a dipped tantalum capacitor...but I agree with you that someone must

I remember seeing 7912ADs and HBs in final test and Cal. They would use them lead that had holes drilled in it for all the adjustments and test points. today at wouldn't be hard to use a piece of luck

Hi Craig, That's not an odd question at all, it's one that I should have asked myself before thinking about blown racks! The fan pulls air in (quite a lot of it), through the PSU module which then

other specifically for this problem fix your problem. I just checked and my 7854 already has this mod, so I'm out of luck. Thanks for sharing the mod anyway. I suppose this problem is in the firmware

Here's what may seem an odd question - does the rear fan pull air in, or push it out? Craig

Adrian, My 7912AD runs happily with no extra cooling, I think the interior layout is designed to pull air past the major boards. I have had it running for a couple of hours with no problems. The

If they are the same as the ones in a 7A18, 7A26 and so on, I may have some. What's the shaft diameter? Harvey

Hmm, I think we are getting there! See 'Getting there'* in album: /g/TekScopes/album?id=62098&p=Name,,,20,1,0,0 So what did I do? Well not a lot except move the stuff to a different

The same article (as 7L5) was also in the 7854 archive. There were no other specifically for this problem There was another about readout issues which may, or more likely, may not fix your problem.

Hi Keith, If you have the extension shaft to pot couplers available, I'd be very interested. They are the cast aluminum with plastic insert ones with 2 #4 set screws, like on the "var" knobs on the

I didn't realize I had that exact same scopemobile, here are some pictures of the drawer that may or may not help : /g/TekScopes/album?id=62217 As you can see there are no runners or

Wizards Workshop was an internal Service magazine distributed to all Field Offices. It contained service tips and mod info on pretty much any supported Tek product. I don't recall how often it came,

Adrian, I don't know what the rep rate of your pulser is but if you aim for one or two cycles of a square wave or just two edges if the mark space ratio is very large, that should be an unambiguous

Thanks, Really enjoyed the story.

Thanks Roger, I'll look at that, the 7A29/7B90P and generators (one of leo Bodnars fast pulsers and an HP 8657B) produce sensible looking traces in a 7854 but that doesn't mean they aren't getting
