Here is the result of taking the transfer function of the EOM Driver (DCC: D1200794-v3) with the bias tee and a dummy EOM from the RF input to the RF monitor output. A Black 143-10J12L tunable inductor (438 nH - 788 nH) was used to bring the peak over 37 MHz. The data was taken using an Agilent 4395A Analyzer which was controlled using the .py .yml and .ini files provided in the zip.
