But given that Keysight calibration includes adjustments free of charge,
the fact it was not adjusted suggests that it can not be adjusted. The AC
board 03458-66502 is obsolete, but the replacement (03458-66512)

https://www.keysight.com/my/faces/partDetail.jspx?partNumber=03458-66512

is $2243.00with a $439 trade-in. So the AC board price is $1794, which is
not inconsistent with a 2100 Euro repair bill.
