Cold testing

You obviously cannot even read.

Show me where I said "flight simulator".

Read it again, idiot.

Then, try to fit within that 2 inch thick bone head skull of yours what things might take place in the world's largest anechoic chamber.

Think of things like the Osprey or the JSF or the F-22.

Oh, that's right... it is miles over your head.

snipped stupid link.

Buy one of the ones I used to make. They are the best in the industry.

And it is not called a "two step drop" It is called "cascaded", and they are not "run in series", one uses one refrigerant to cool the primary of the secondary, which uses yet another, different refrigerant. If anything that more closely models a parallel configuration.

Ours go down to:

Extreme Cold Temperatures Temperature chambers with mechanical refrigeration systems achieve temperatures as low as -84°C (-120°F) and temperature chambers with optional LN2 achieve temperature as low as -184°C (-300°F) for fast temperature change rates.

I'm guessing you were not in the sales department.

How big are your 'parts'?

I use a cryocooler that cost me about 500$ inclusive shipping. can go down to 70 K, and up to 50 C easily on the hot side...

-55 C should be no problem in a minute or 2 even in open air with some small peeseebee mounted on the tip.

It is not suitable for bigger things, but yoy can mount the tip in a well insulated box and then a few cubic dm should be no problem. I have seen units like that for sale.

And if that is not enough you can make your own liquid air, LN, O for a bit extra cost,

I also have an electric oven to bake pizza :-)

What does it do?

Custodial.

14 racks, with 1ps resolution. Rrrriiiiiiiggghhhttttt. Sure, we believe you AlwaysWrong. What was the accuracy, 1ms?

AlwaysWrong, still.

If it's short term maybe you can rent a tenney JR. Cheaper than owning one.

Cheers

No further information can be provided.

You'll just have to think a bit, Johnny.

You ain't real bright about things, boy.

Literally hundreds (over 1024, in fact) of equal line lengths, and phase shifters and attenuator controls, all at several GHz. All perfectly synched. Unlike you idiots.

Far to elaborate for a retarded twit like you to grasp.

And sorry (not), the details of which are not available to a dork like you either.

If you are gonna rent, you might as well rent a better name brand than that POS maker.

It doesn't even look as if they are still in business even, so it would be a refurb unit, at best. Oh boy... great choice... NOT!

Resolution is cheap. Accuracy and jitter are not.

It's hard to get delay tempcos (ps/degC) or jitters (ps RMS) down into the single digits.

Our arbitrary waveform generators are $36k each, our cost.

Each 16 channel module carries one. Do some math, Larkin.

You guys are still losing.

Oh, and we got fully approved. That is why several more of the same or similar system were bought by them.

Looks like the battle is over, and you definitely lost, big time. Bwuahahahahhahahahahhahahhaa!

You obviously do not know much about temperature controlled environments.

You probably drive your noisy crap with switching supplies too.

So, it is hard... for dopes like you.

I can believe that (having designed a 100ps clocking system, more than thirty years ago). I *don't* believe this group's sanitation engineer knows anything about it.

Ever look in a mirror, DimBulb?

"Perfectly"? That's pretty accurate. How is this "perfection" accomplished?

It's OK, AlwaysWrong. We understand your limitations.

Then perhaps you shouldn't even be talking about it, Nymbecile. You certainly don't know anything about it.

I once used dry ice with one of those beer store styrofoam coolers and a small fan inside (to stir the air) to get down to either -40C or -55C (I don't remember which). I did get some frost on the pcb, but it was not a problem for my design. I left power off until I needed to make the measurements.

With more care to insulate better, you might reach -55 with dry ice.

Cheers, John

I did fail at sanitizing the group of the SHIT that is KRW.

Likely because that is not what I do.

If I did, you and your entire bloodline would no longer exist.

You are doing a fine job of flushing yourself, however.

Run ANY PCB assembly at cold temp levels in a bath of Fluorinert. ZERO water inclusion.

But I know you are too dumb to even understand why.

D'oh!
