Whie I'm sure this may be a cardinal sin, this is actually about a Thermo TSQ Quantum Ultra that is making me want to beat my head against the wall.
The quads will not dip in any way. I continuously get errors with any dip attempt. I've checked the RF Amplifier PCBs with an oscilloscope and that data was interesting. AS you can see below, only the RF Freq In (yellow) is good on the Q1 RF Amp PCB, while the RF Output is bad (blue). On Q3, neither are working. Has anyone encountered anything remotely similar? I've tried a whole slew of things as I've been troubleshooting and happy to share those details if anyone actually responds to this plea for help, ha.
