Quick post of plots and data; I'll fill in more detail tonight.
TL;DR: I pulled both green PDH boxes and made LISO models, compared TFs and noise levels.
Pictures of X and Y boards, respectively
 
TF comparison to LISO. (Normalized to coincide at 1Hz)

Noise comparison to LISO

To Do:
- Figure out why TFs were made differently. Check PM response curves of PZTs to see if they are fine, or need tweaking.
- Make boosts useful. Both are currently integrators with corners under 10Hz, which is already pretty suppressed.
- I just noticed that the X board is missing C25, which should be a 1uF cap on the positive power pin of the primary TF stage opamp. This should be inserted.
All data, EAGLE schematics, LISO source and plots in the attached zip.
