Riju did the measurement of the MCREFL PD.
I found data files in her directory on the control machine.
I was not sure how much was the transimpedance of the DC out.
I assumed the default number from the circuit diagram which was 66.7Ohm.
This may cause the error in absolute caribration of the transimpedance but the shape does not change.
The RF preamp is gain-peeking at 250MHz.
Here is further characterization of the PD response.
As you can see in the second attachment, the 3dB cut off of the resonance is about 2.3MHz.
The game plan file in dropbox was also modified.
