Re: [volt-nuts] Get 10K resistor calibrated in UK

2017-11-08 Thread Alan Ambrose
NPL i.e. the UK national lab, are also surprising flexible and cheap. Looking 
at their schedule for '15/'16 (the one I happen to have to hand) they had 10K 
ohm cal 30-Nov-15 to 11-Jan-16 @ £510. They also had voltage cal October and 
March at ~£420.

[volt-nuts] 732A drift

2017-08-30 Thread Alan Ambrose
>>> My 732A e.g. has a drift of only about 0.2ppm 
>>> pa over a couple of year

Hope you don't mind me jumping on this thread and asking a basic question: is 
there any kind of procedure for the 'enthusiast' (say with single 3458A/single 
732 and not say 4x732) to measure the drift of a particular 732.

Re: [volt-nuts] local *nuts meet-ups

2016-03-02 Thread Alan Ambrose
Hi,

If anyone is interested, there's some local *nuts meet-ups in the fledgling 
state. See:

http://www.eevblog.com/forum/metrology/volt-nut-meetings-and-gatherings/

I think there's enough already for a London, UK group and also one or more 
German groups.

Regards, Alan

Re: [volt-nuts] *WAY* too expensive for even Keysight to redesign

Hi,


 Fluke has ... replaced the vacuum display with an LCD.



I'm starting to worry about the great US test gear manufacturers :)

Re: [volt-nuts] *WAY* too expensive for even Keysight to redesign

Hi,



Come on, we all know how this will end... a raspberry-pi like processor running 
a virtual machine emulating the original processor (running the same firmware) 
and taking care of everything digital, and the analog asics doing what they do 
best HP48 style.


Daniel, that made me laugh :). Begs a question though - even if Agilent or 
whoever they are called today don't have the smart personnel or the market 
incentive to do a good job of bringing the whole thing up-to-date, they could 
add a better display, better connectivity, more stats, smaller packaging, more 
modern components etc and leave the clever analogue stuff alone. Sooner or 
later, someone is going to want to move the start of the art forward from the 
late 1980's.
