FEI     Firing Error Indicator.

FID     FIDucial. 

FIDO     FIDucial Output. a chassis which is used as a local timing reference. The FIDO extracts the fiducial pulse from the 476 MHz MDL. The output of the FIDO is a 119 MHz signal with a missing half cycle to indicate T-zero which is fed to a PDU.

Fiducial     A pulse created every 2.8 milliseconds, doubled in amplitude, and used as a marker for timing. This double amplitude signal is superimposed on the 476 MHz as it is synchronized to the zero crossings of the 3 phase PG&E signal and to the damping ring revolution frequency. The fiducial is processed by the FIDO and goes to the PDU.

Fiducial Output     See FIDO.
