To abuse the car analogy some more, it's like your car has a shimmy that you can't feel at 70 mph on the freeway, but at 100 mph on the track, it becomes obvious. In normal use, driving to work, going to the grocery store, going on vacation, you'd never know it was there.

Poor analogy. Cars are mechanical things that can get worse with time, a shimmy may cause eventual self destruction of a part. Electronics doesn't generally do that. If it works now it'll likely still work exactly the same in 10 years time. Subject to temp variation and component aging.
Forget about aging - just about what is happening now.

I am. All evidence so far shows shows Rigol have fixed the problem. Unless more evidence or productions variation comes to light in the future, then that's the end of it.

@ Bud
Do you imagine the HW & Firmware settings Rigol has used to impact on possible ADF4360-7 failure in the future?
But after reading some of the latest posts in this thread another question
comes to mind and that is hypotheticaly, if changes were made to the PLL
hardware would later FW revisions then have to be split into pre and post
hardware changes or could a single FW cover both or all HW versions.

Sorry tautech, I do not understand the question, can you explain ?

He's asking if you believe the lifetime of the IC could be affected by operating under these conditions. Can't see it, myself.

Just wondering.....if (as Bud has identified) it's operation OUTSIDE manufacturers recommendations might impact on the IC's MTBF.
Anybody put a IR temp gun on it to see if it's running hot?

Hello-
If one decides to unlock all options on the 1054 (including 100 MHz)- upgrade the firmware before doing so or afterwards?
Thanks!
I'm wondering whether this pseudolocked PLL condition is stable enough across the operating temperature range of the instrument. I recall some users mentioning that on a cold boot the jitter was there slowly declining to invisible as the thing warmed up.
For some reason, whether insufficient phase margin of the loop filter and/or poor isolation from the ADC (load pull), the phase error seen by the PLL chip is too much for it to assert the Lock mux out pin.
If so they had confused VCO Core Power with Output power, which is a separate setting. Told that 500 times before but let me repeat again - they have no idea what they are doing. But general public in this thread , which should be called consumer blog , not engineering one, seems to feel ok with it. So best of luck to everyone using their "shelf decoration".
