check on Ebay ? or ask Keysight if they have some left ....
And if they do, you have to be an business to order from them
Just paid 200 $ CAD on ebay to get an 34410a vfd ?? ill know tonight if it was a good purchase loll no part available at Keysight
And sadly you may have to buy another meter for the part
or you try to fit some oled display project done by Qu1ck, not sur if its code compatible ...
