Subject: PZT response for the innolight 

Innolight 10 rad/V @ 100kHz => 1e6/f rad/V => 1MHz/V

LWE 30 rad/V @ 100kHz => 3e6/f rad/V => 3MHz/V

---------

BTW, don't let me calculate the actuator response everytime.

The elog (=report) should be somewhat composed by the following sections

Motivation - Method - Result (raw results) - Discussion (of the results)

Quote:

  We realized that we had measured the wrong calibration value; we were using the free-running error signal with the marconi far from the beat frequency, which was very small.  When we put the Marconi right at the beat, the signal increased by a factor of ~12 (turning our original calibration of 10 mV/rad into 120 mV/rad).  The re-calibrated plots are attached.
