... Don't use them, but thanks for the warning... <grin> ... Was afraid of that situation. ... as if..... ... This is probably an EOL failure, so it looks as...
AIL / Eaton seems to be pretty much of an orphan although they made some really high performance stuff, like SAs and Synthesizers. If anyone is interested, I...
Hello, list. I'm looking for someone who has a manual for the old HP 130A 'scope. If that person, is you, please contact me off-list. I have the power...
Well, I finally came around to replacing the sockets on one of my HP 5370A counters. I have two of these counters and both of them have had severe socket ...
Hi I have recently acquired an HP 8970B at work. I am familiar with the 8970A which was fairly easy to use out of its frequency range in amateur radio...
Hi, Conrad -- If nobody here knows the answer to this, you might try posting the same question on the WA1MBA microwave list ( http://www.wa1mba.org/reflect.htm...
I have no idea who the manufacturer of the original sockets were, I still have them, but I did not see any marking. They looked really cheap, very unusual for...
... Back in the early 70s, we replaced them by the dozens in music electronics. TI's grabbed the pin by the edges. Burndy's grabbed them by the faces. Augat...
I have the repair manual, but it has only very basic ops info in it. Beyond all the obvious, most of the questions I've had have been answered by reading the...
Hi Conrad I don't know why you can't use the 8970B in the same way as the 8970A - the differences between the two were minor ('B' can have up to 4 ENR tables,...
... 8970A - Nor do I but unfortunately whenever I try I get E42 'No LO on SIB bus' I do not have anything on the SIB bus, nor do I want anything on the SIB...
These grab the pins by their face, not the edge. I am not sure why they are so bad, because I could not see widespread evidence of corrosion, and the contacts...
Most likely, they are plated with tin, and grow a great crop of tin whiskers. Also tin, when it oxidizes, isn't that great of a conductor. I doubt that deoxit...
First problem you can encounter using 1.3MHz is that the immage frequency is going to be awfully close to the Receive frequency so you will measure double...
... Could have been Robinson Nugent. These sockets were really cheap but they had one quality that was missing in many of the high grade sockets. That was a...
Yes, I thought about tin wiskers. I have not looked under the microscope, but a 7x magnifier did not show anything. When I applied the Deoxit, I brushed it all...
OK from looking at the manual measurement modes 1.8 or 1.9 seem to be the most appropriate, you have to turn the Control function for the 8971 off with spec...
That may have been the type, the chips were really tight in the sockets, which is why I found it strange they would be intermittent in the first place. There...
Hi Lothar I'll give it a go tomorrow although I suspect that I have already tried this and still got E42. My intention was to up-convert from 1.3 MHz into the...
I have an 8970B in my home lab. I have made many microwave noise figure measurements with it. As I do not have any software or the means to control it over the...
Just picked up an 8640B from ebay. Everything works ok except lock would hold only for 30secs after overnight warm up. Power supplies are within spec and and...
another way to do it would be to enter a offset on the 8970B, i dont understand why HP makes things so darn complicated, all DBS converters are measured...
another way you might want to consider is to do a Y-Factor measurement controlled by labview, you can use a AF Spectrumanalyzer such as the 3585A or something...
My 8410B frame has some rectifier diodes in the power supply that have run VERY hot and I would like to replace them. They seem to be garden-variety...
You're right.... can't find anything on the DO-29 package..... but, what's the part number of the diode? Possibly a cross reference to an NTE product can...
While you are investigating, you should look to see if something, like a tantalum with low resistance, is causing an overload in current..... not enough to...
