We lost lock while going through the 9MHz reduction state.  This might be the second time today, although the first time I thought it was due to the extra 6dB of gain in the CARM loop. 

Perhaps part of the problem is that the PD digital gains (which get increased to compensate for the actual modulation depth reduction) are ramped over 30 sec, while the analog EOM driver is just making 3 discrete steps over 6 seconds.  We need to look into this.

However, while looking at the state REDUCE_RF9MHZ_MODULATION_DEPTH, I saw that the ASC 45 MHz photodiodes were getting their digital gains increased by 3dB.  Ooops.  I have fixed this, however we'll need to pay attention to the ASC loops, that in NomLowNoise they'll now have 3dB less gain then they were having.  Should be okay, since all the loops are stable and were set before the modulation depth reduction.
