OSA at AS port

Sheila, Terra, Jamie

Today I set up an OSA on ISCT6 to look at sideband assymentry at the AS port.  Mark stayed late to get an MHV cable together,  and we were able to look at the asymmetry in some of the 50 Watt locks that Jenne and Stefan had.  Roughly, we saw that the asymmetry of the 45 MHz sidebands is 66% in power, while the 9 MHz sidebands are about a factor of 3 different in power.  We have left the set up in place for now, and we will make some plots tomorrow.
