LIGO Document D1001530-v7
- A schematic and associated documents detailing the characteristics of the aLIGO ISC Whitening Module
- Version 7 added text notation describing the ECR (E1600192) that removes capacitors in the differential input stages of the last two channels. This modification is only applied to the OMC DCPD Chain, and was done to permit better visibility of transmitted PI modes in the 10kHz to 80kHz band of frequencies.
PCB revision 3 is still the current version of the PCB
