Important facts about the LPCA of SV:

preamp path is controlled by shorting pins on Port A in the coil connector
• Head TxRF is routed through the interface module, this is done to “tap-off” the head T/R
bias
• Head T/R bias is used for preamp protect switching in the interface module
• Multi Coil bias is added to the RF coax lines in the port connectors
• Bias is added to Port A in the MulticoilInterface Box
