Definitions: Frame Ground - refers to the chamber metal frames, cable shields, external ground planes of printed wiring boards (PCBs), crates and racks. Possible points (to be investigated) where this may be connected to BNL earth ground are the magnet frame, the Low Voltage High Power (LVHP) crate, and the racks containing the LV & HV power supplies, and the LeCroy high voltage power supply. SIGR-HV - derived from the chamber card SIGnal Return - High Voltage, this is the ground side of the chamber signals, and low and high voltage power. definitions
