Hi, thanks for a lot of information. I would like to know more about RT1: you say that is a 10 ohm NTC.But, the ID in one of sides is 0033. Do you now how I can get a similar one? Thanks in advance.

Right, and silly me, I jumped on the wrong thread, or the right thread with the wrong subject. Head-slap time! Jim

Someone else is doing this mod; I’m one of the followers hoping to put it in my 400EL. Jeremy Jeremy Nichols Sent from my iPad 6.

Sposed to be 600 ohms, I think. Yep, the needle moves with nothing connected. I bought this thing at the TRW swap meet back in 1992 or 1993. I haven't used it much, but it did help me verify my own

With nothing connected? Whats the input impedance of the 400E? -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Me, too. I have a 400E and just checked it after not having used it for some time. On the most sensitive range, -60 dB 0.001 V, the needle moves around a fair amount with open input BNC, and if that

Sure, it'll fit bc it's nothing more -- at this point, in my mind -- than a simple part-for-part swap. The BNC retrofit is a complete no brainer, complicated only by the need for a ground-isolated BNC

I'm interested to hear about the low noise mod you make and if it would fit into a 400E or 400EL since they have BNC input already.

Ah-HA! Yes, THAT is the scumbag. I thought his drek was vomited upon the world in the 1970s, seems it was later, in 1983. At 80 years old, it hardly seems worth choking him now, though it sure is nice

Dave McGuire, I happen to know exactly who one of the two men is: https://en.wikipedia.org/wiki/Michael_C._Jensen Vladan

That would be good. I started such a thing about eight years ago, using MediaWiki, but it was overrun by spam pretty quickly so I shut it do

That's a lot of documentation. Most of the HP/Agilent/Keysight VXI manuals that I have were downloaded from Keysight's web site, and the Tektronix ones were obtained from Tektronix. Some of it has

I had my day with optimizing "done" software once, back in the late 70's. I was an intern with United States Railway Association, the creators of Conrail. I was part of the effort that was known as

Oh, I completely agree, but I don't think most newly minted coders do.? Besides, releasing poor code means you get to stay employed in order to fix it. The main database I was using was constantly

It DOES, though. I feel (and increasingly I think I'm alone in this!) that inefficiency is inherently bad. Having lots of memory available doesn't make code unnecessarily fat...laziness does.

Part of this is, of course, due to the size and cost of available memory.? Back then, software of any kind (usually) had to be compact and elegant just in order to fit into the available space.?
