I have now sorted through some of the circuit boards that I bought a few months ago. The first lot for sale are the AC boards --3458-66502.
These boards were purchased as a job lot from a lab in the UK.
Shipping world wide is not a problem.
I have tested these in a working 3458a as follows:
Power on test
Full test
ACAL AC
Some boards have also been tested at 1/10/100mV 1/10/100V
Others have been left on test for about 4 hours & then tested again.
I have not done a full AC calibration on any of these boards. I used the calibration constants from the AC board fitted in the 3458a
Boards that pass the above tests are £450 ea if bought singly
Boards that fail are £150 ea if bought singly
If anyone is looking for multiple boards then make me an offer.
IF ANYONE WANTS A SPECIFIC TEST DONE THEN I AM HAPPY TO SEE IF I CAN HELP.
These boards may still be available from Keysight "Limited to quantity on hand of 5" if their web site is to be believed at £3039 plus VAT with a trade in board returned. The A3 board is also mentioned on the web site but all of these are sold.
Payment can be cash (collection only), BACS transfer or PayPal.
