Re: Service notes HP5343A, Count about 350MHz wrong
OK, there is a service note in the 5343A Operating and service manual: 5343A-30A, where the possible solutions are listed. Apparently, the 350MHz freq error is caused by the open ground loop

Re: HP Basic for Windows 6.33, printed documentation
Great find, and most users might use a Windows 95, 98 or NT Virtual Machine? If they're very lucky it might run in XP? I had trouble with installing VMware on an older Core i5 x64 machine here, the

Re: 1 mw - 0dbm lab calibration
I'm not sure what is inside it but I assume it will use a pair of auto balancing bridges like the 432A system. I'm also assuming they use some form of 4 wire IV method to measure their own mount
