I have a E4402B that had firmware version A.09.02 and I updated to the latest (A.14.06) on the Keysight site and after the update option 1D5 no longer appeared. Option 1D5 is the Hi Stability Freq Ref.
Thanks,
Victor

Hi Victor,
The firmware is set up in such a way that upgrading from A.09.02 to A.14.06 should not cause option 1D5 to disappear.
To get to the root cause of this, I need two pieces of information:

Chris,
I found the cause of the problem. The company I purchased this from replaced the RF deck due to an unrelated failure. The replacement deck did not have the 1D5 option. The original E4402B did have the option. In doing the firmware update the missing option was detected and deleted. (Anyway this is our theory on what happened).
I will be add the 10MHz High Stability Oscillator again in the future per E4401-90387.
I appreciate your quick response.

Just a followup to this issue. I did open up my RF deck and soldered in the high stability oscillator. When all was put together option 1D5 was found and everything is good again.
