Just to clarify: The Grass Valley Group existed as an independent company for many years. I was first exposed to their products--and visited their factory--in 1974. The company, I believe, was

The PDR series are the video servers which are Tek/Grass Valley products called ProFiles. The software would be rather useless without the specialized

Does anyone know what 'TEKTRONIX PROFILE PDR 100 or PDR 200 SOFTWARE' is and what does it do. It has been offered on e bay number of times, looks like guy is growing it in his backyard. One of current

The power of three is close to light output re-rating, the actual number is 3.5. As for lifetime re-rating I did not see any restriction on the ratio of voltages. Bear in mind that those numbers are

Well, that is novel approach to collecting. Most of us buy hardware and then look for manual and you put that thing upside down. Regards Miroslav Pokorni

pardon me ; the intensity delta change is about the cube root "exp-3.3" radio shack was selling little grain of wheat bulbs im not sure if they still do that are used in

hello all, i picked up a set of manuals on ebay recently that pertained to the 1503 and 1501, which i kind of expected to be like the 1502. turns out that the 1501 is one of a few instruments tek

The empirical data for tungsten light bulbs show that life is extended by a number equal to 12th power of rated to applied voltage ratio, what in case of 12 V rated lamp run at 5 V would be around 36

Ok, off-topic, but fun. Test fixture with seven cards fresh out of card-stuffing/wave solder. Owner of firm brings the bankers by and explains my "cool" automated test setup. I'm on a deadline, so

I will start you on that, Craig, though. But do not feel bad, the issue is equally confusing to Motorola employees, too. Some years ago, right around time when that 'shrewd' business move of spin-offs

Electrolytics can make a spectacular and quite dangerous 'exit from the scene'. Personally, I have seen number of tantalums which failed and not every time the cap was mounted wrong way. Frequently,

Current part from ONSemi (56c each) (Motorola as was, before confusing name change. Don't start me on that beef!) Craig

Well, I had an electrolytic blow up in my face once. The pressure relief was facing me, and POW! Fortunately I wear spectacles, and that stopped the goo going in my eyes. I can't quite remember

radio shack might still sell some wire lead bulbs that might work. Using a 12vlt bulb running at 5 vlts should last a long time "most consumer electronics bulbs arent rated

The interesting thing is that this cap wasn't really "shorted". Part of what threw me off for a while during this whole process is that the 110V supply is really low-current compared to what I'm used

I am curious how much of real visual effects (smoke and flames) did you get out of that cap. I do not doubt that there was enough energy in the circuit but a ceramic disc does not provide much of

You are talking about 50 Msps? That puts your memory cycle to 20 ns, a pretty tough requirement. Try Cray's gig with memory: butterfly it. Use registers to store odd samples and on even samples write

From what I remember reading about those 'aged and selected' bulbs that Tektronix used, they were selected for light output. I do not think that those long life (50 000 hours) light bulbs are risk,
