Abstract:
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.

Notes and Changes:
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.
