Haven't run into that battery problem.. but rented the 51717 from an Ebay offerer for low $$ in the past. I simply sent him an email saying, "I see you are selling that unit in your ebay store, can I rent it from you for a week"? And he did.. I did have a power supply go bad, and simply bought an 83480A digital comm analyzer for about $200 on Ebay, that has the same exact platform, and one can re-use the parts on the 54720D (power, monitor, etc etc). That entire unit came cheaper by margin than trying to buy just the power supply itself. bye, Said In a message dated 4/17/2012 03:38:41 Pacific Daylight Time, azelio.bori...@screen.it writes:
Good, the HP54720. We have one but, unfortunately, lost the calibration (backup battery dead). Now it need the HP51717 to complete the calibration. So be warned not to let the backup battery go flat: replace it trying to supply, with a diode, the NVRAM. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
