We looked at the different outputs of the MC servo board to make sure they make some kind of sense. As per my elog 6625, the names of the channels were wrong, but we wanted to confirm that we have something sensible.
Currently, OUT1 of the servo board is called "MC_F" and the SERVO out is called "MC_SERVO". We looked at the spectrum of each, and the transfer function between them.
You can see that in addition to a 2kHz pole, MC_L also seems to have a 10-100 zero-pole pair.
Also, while cleaning things up in the models, I fixed the names of these MCL/MCF channels. OUT1 is now called MC_L, and is connected to ADC0_0, and SERVO is called MC_F and is connected to ADC0_6. Both MC_L and MC_F go to the RFM, and thence on to the OAF. MC_L (which used to be mis-named MC_F) still goes both to the MCS model for actuation on MC2, and to the OAF for MC-OAF-ing. Right now MC_F is unused in the OAF model, but we can change that later if we want.
