A block diagram showing the proposed design topology for a chassis that allows transition to a low voltage drive mode for noise reduction in the ESD drive chain on the ETMs. This chassis also provides a 40vp-p drive capability. Scattered features existing in the initial ESD subsystem installation (bias voltage low pass filter, 10kohm series resistors) are consolidated into this design.

Version 10 Notes
Changed order of quadrant selector and high-pass filter to eliminate two stages. Changed quadrant selector to relay based solution to accommodate higher voltages. Updated pole-zero frequency from 40Hz zero to 50Hz zero to accurately reflect the as-built schematic.
