Is it possible to adjust white balance on a PVM-2030 or PVM-2530 to 6500K/D65?
They come factory calibrated to 9300K and it seems like Sony intended for them to primarily be used like this since some locations in the manual state that you should target calibrating to 9300K.
Before I get inside mine and start adjusting what appears to be only a Red and Blue CUT OFF adjustment, I was hoping to find if anyone has successfully achieved 6500K on one of these older 30-series PVMs.
See service manual WB calibration procedure below:

Whatever calibration was done at the factory for D93 must have drifted away a long time ago already, so whatever target you want to hit whether D93 or D65 would require a full white balance adjustment with appropriate signal generator, scope, and software. And it's really difficult to find both appropriate software and hardware for this, especially an old scope that needs calibration of its own to produce accurate results with a CRT. I'd say you're much better off just putting it next to a display that is confirmed calibrated to your desired white point target and simply adjust by eye.

I have a signal generator, a colorimeter, a spectro, and a variety of calibration software.
Would it be possible to do it with what I have?
Do you need a scope?
Yes you can most certainly calibrate the monitor with your current equipment. Only thing is that the PVM-2030/2530 lacks digital inputs, making SDI unavailable (which otherwise makes the calibration process much easier with modern workflows). Basically you must use a DAC, unless the generator has analog output that the Sony can display.
What kind of signal generator are you using? I've got a couple of VideoForges and one of them only ouputs progressive video, making it unusable with 15KHz displays.

I have a Portrait Displays VideoForge Pro, but I'll run it through an HDFury x3 which I've tested to be bit accurate in Full Range RGB by comparing it against my DVDO iScan box which others have confirmed to be bit accurate in Full Range RGB. The nice thing about the VideoForge is that I can automate it from CalMan.
I ended up finding this video where someone (who seems experienced with these PVMs) talks specifically about calibrating them to D65 (.3127/.329): https://youtu.be/yoBqm4ThJxw
