I've taken a DARM Open Loop Gain TF for this lock stretch (after adjusting the DARM gain to match prior measurements). I'm going to start processing the past several DARM OLGTFs (see LHO aLOGs 18662, and 18709), including this one, using our new precise knowledge of the actuation scale factor (see LHO aLOGs 18711 and 18718).

Since this is a DARM OLGTF with a new low noise ESD driver (though without the LP filter engaged), and the new hierarchical control scheme involving all three lower stages of ETMY, I figure I'd over-document it. Attached is a conlog and screen shot of the MEDMs for all the relevant digital filter banks and Binary IO Control involved in the DARM loop for this kind of lock stretch.

Stay tuned!

This darm OLGTF has been committed to the CalSVN under
