Good news: the issues with our CMU200 have been resolved without having to involve any expensive repairs. The technical person at R&S (as opposed to the non-technical customer service front end people who originally gave me that outrageous price quote) told me there were two issues: 1) The tech fellow said that there were two ribbon cables loose inside the unit. I am quite sure that I did not pull any ribbon cables loose when I was replacing that Rx/Tx board, so either they came loose in shipping, or someone was tinkering inside this unit with insufficient clue prior to me. Once the fine folks in Maryland reconnected those cables, the EEPROM reads which originally failed started working. 2) I don't know what kind of tables are stored in which EEPROM, but the helpful gentleman from R&S said: > After further review, it appears the RXTX module that was replaced had > incorrect tables loaded (probably from its previous location).

Of course it is a given that whatever tables were loaded in the EEPROM on that transplanted Rx/Tx board had to be incorrect for the new put-together CMU200 configuration and needed to be corrected through calibration - but I am guessing that because of the transplant, they were incorrect in some more serious way that R&S's "regular" calibration procedure was not prepared for. In any case, the outcome is that the incorrect EEPROM tables have been corrected, the unit has been fully calibrated, and they already sent me the calibration certificate with detailed tables and charts of the unit's exact performance after the calibration, which look beautiful: https://www.freecalypso.org/members/falcon/calibration/CD_5000-309076293.pdf They haven't told me if they already shipped the calibrated CMU200 back to me or if they are still in the process of packing it or doing the paperwork or whatever, but it shouldn't be much longer before it is back in my motherly FreeCalypso lab. They haven't charged my card yet, but I expect the charge to be what I originally agreed to for the calibration - $1405.00 USD, which is perfectly reasonable for the perfect calibration and semi-repair job they did, not the other $6415 repair quote which was NOT reasonable.
