content: Time to part with one of my 3458A's. It was HP 3458A branded meter, with next service:* Replaced ADC A3 assembly to fresh board, verified stability against Fluke 732B ($1300)* Replaced front panel assembly and 5-way low-thermal terminals to brand new original part ($390)* Replaced NVRAMs with original MAXIM brand new parts ($90)* Replaced fan, all electrolyte capacitors on power supply boards with +105c/long life top brand caps ($40)* Artifact calibrated from Fluke 732B and ESI SR104 standards (National level calibration by Quantum standards on both just month ago, with traceable to SI to 0.02ppm DCV, 0.16ppm Resistance) ($ $ $ $)* Fully calibrated and tested against in-spec Fluke 5720A/5725A calibrator rig.* 10V INL confirmed to meet 0.1ppm specification, tested against six other 8.5digit DMMsAll this means it is not a cheap parts unknown condition box, but instrument ready to use for most demanding applications.Price:$4500$5000USD or trade to other T&M (particular interest is in Tek DPO7k series scope)*Payment via PayPal, shipping cost $200 from Taiwan to US/EU.I'll upload photos later as well.

content: Pictures of the actual unit. Price$4500 USD + fully insured express shipping (~$200, 5-10 days US/EU).Obviously pass all self-test and ACAL many times without any problems.I'll have another high-end 10VDC reference and 10kOhm standards calibration vs top National Quantum Lab again in few weeks, so buyer have a chance to get <30 day 3458A spec on DCV/Resistance, directly to SIHere are photos of the guts, no shenanigans or rust hidden inside.Quick test vs calibrator as of today, July 30. I'll post generated calibration report tomorrow, 2am here.DCV directly against calibrator:Resistance tests:DC current:AC Voltage, 10mV, 100mV, 1V.AC currentFrequencyAll photos in hi-res , single ZIP-archive- 150 MB.
