Up for sale is my (spare) 3458a. I bought 3 of these earlier this year for a project -- sorting out a large lot of 3458a boards I purchased. Of the three this is the only one that actually works as intended.  I have checked it for drift (per 3458-18a) twice. First time was before I refurbished it & the second time after I finished.

I have replaced:
Mains input filter
RIFA caps
Inguard & outguard PSU electrolytic capacitors
Dallas NVRAM with FRAM
Installed Opt 001 SRAM
Firmware updated to 9.2

I am posting detailed results for the drift tests plus a comparison against my (Keysight calibrated) 3458a & also my 34470a.
Happy to ship at buyers cost as I have the packing that Keysight used to return my meter from a previous calibration but collection & inspection is much preferred from Torquay Devon.

Any questions? Just ask.

Price £4950. Sensible offers will be given serious consideration.
