Re: Foam conductor problems
Does it have to be conductive throughout the volume, or would surface conductivity do? There are plenty of companies selling conductive plastics. http://www.boedeker.com/esdmatls.htm was my first

Re: Foam conductor problems
No, he is referring to a type of interboard connector which consists of stiff wires embedded in elastomer. It's in the same family as zebra strips, but works for higher current applications.

Re: [TekScopes2] "Event logging" T & M equipment?
Companies like Dranitz make boxes specifically for that purpose. Older ones can be bought pretty cheaply. They will likely need new batteries. -John ==============

Re: "Event logging" T & M equipment?
Why not make one? Take anyone's microprocessor board (Arduino would work well), feed it with AC, biased to half the supply voltage, then do a fast A/D on it. This gives you a running peak to peak

Re: How to test a mixer on a hp 8559 plugin in a 853 main frame
How about the other tests recommended? Throw some low level signals at the various IF's and see if you get a response. If the IF's work, could be a bad mixer (I doubt it with no 000 response), more
