If anyone was ever to "review" such a device the actual power consumption would be usefull to know. The likely savings in electricty costs could provide some justification for replacing one of my HP5370B's (:
Devices that could also easily run from a DC power source could have merit as well. --- On Tue, 11/1/11, Jose Camara <[email protected]> wrote: > From: Jose Camara <[email protected]> > Subject: Re: [time-nuts] VIGO time interval devices > To: "'Arthur Dent'" <[email protected]>, "'Discussion of precise time > and frequency measurement'" <[email protected]> > Received: Tuesday, November 1, 2011, 11:50 PM > There seems to be a deluge of these > OEM counters, mimicking the 53132 > operation, with a bit better "specs" and built-in 3rd > channel. > > Berkeley Nucleonics has them, Keithley > has them, they all must come > from the same Chinese OEM.
