I have three devices (2xHF-60105, 1x HF-6065), which has been upgraded sometime ago with firmware 41. When the preamplifier (option 020) is turned on, signal under test fall down near to 15 db. Now, how can I remedy this problem?
Thanks

You cant, because BETA41 changes the complete calibration base to a new calibration standard.
Thats why you have multiple warnings to upgrade to BETA41.
Only original BETA41 shipped units work fine because they are allready calibrated with the new standard.

Snip

Yes, you say this now, but when I upgraded that units there was no warning at all.
And after this I have discovered the problem for a claim of a customer. Now we have three units unuseable.

There is a big warning in the ChangeLog and in the firmware updater itself when you hit the "Perform Firmware Update" button:
