We'll all probably want a spare unit also.

Does anyone know the manufacturer and part number of the connectors used on the
HP-3458 voltage reference board?
thanks,

Charles,
I looked over the list of videos on eevblog but I didn't see anything on Datron
equipment. The list is not indexed so I had to manually search the list. I
looked several times to no avail. Do know which episode it was?

Frank,
The specs for the ICL7650on page 3 of the data sheet show a max bias current of
200 pa AT 85C (the ICL7650b is no longer available), higher than the LTC2054 at
150 pA at 150C. The 845 will not be operating higher than 40C ambient, for a
typical test lab environment, and the temp rise
John,
I looked at the LTC2057 but it doesn't go down to 3V operation (4.75 V min) and
I want to power the Fluke 845 with 3V lithiums. In addition, the LTC2054 has a
lower input bias current (1 pA at 25 C). I wanted the lower bias current since
I want to use the circuit to upgrade an HP-419A
. Just
send me an e-mail request.
