Sheila and Daniel took several TFs of the EX PDH open loop on friday. I have attached the files, and a matlab script for the graph. These TFs were taken w. the following configuration:

PLL Servo Board:

• Input 1 pol: neg
• Input 1 gain: -4dB ** note this is different from nominal setting of 0dB due to a bad burt restore
• Common Comp: ON
• Boost 1: OFF
• Generic Filter: ON
• Fast Option: ON
• Fast gain: -8db
• rest off/zero

PDH Servo Board:

• Input 1 pol: pos
• Input 1 gain: -11dB
• Common Comp: ON
• Boost 1: ON
• Boost 2: OFF
• rest off/zero
