Hi Nigel - could you post the files on KO4BB's manuals site? There is a version 3944 already there. Go to: http://www.ko4bb.com/getsimple/index.php?id=manuals Click on "upload instructions" and/or search for 53132.

A couple of years ago I upgraded a 53132A with serial prefix 3546 from firmware version 3403 to 4613, just a straight replacement without any problems so I would expect that your upgrade should have worked ok. The devices I used were Motorola M29F010CF-90 and I've seen confirmation from another user that 29F010-120ns should also work ok. If it's any help I can send you a copy of the firmware files I used. They came from EEVblog with comments that they were copied from HP originals supplied in 2010. Regards Nigel GM8PZR I recently acquired an older HP 53132A frequency counter offeBay. It did not come equipped with an option oscillator. The standaloneperformance of the existing oscillator is extraordinarily poor although thecounter works well running off my house standard. I decided to update theversion 3703 memory to version 4613 which I have installed on my newer Agilent 53132A.The serial number prefix for the eBay counter is 3736A so I assumed that theupgrade would work based on the HP assembly – level service guide that I have. When I installed a freshlyprogrammed set of 4 ROM’s the counter would not power up. The fan ran butnothing else. When I re-installed the 3703 chips everything returned to normal.Is there a hardware difference between the older and the newer HP/Agilent boards or am I missing something else? _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
