HF4x8

Switching Module

The HF4x8 is a VMEbus compatible 100 Mhz switching matrix with comprehensive Built - in - Test Equipment (BITE) capabilities. Modules may be joined in tree fashion via the top edge BNC connectors to create 8x8, 8x16, 4x16, or 4x32 configurations (4 signal highways maximum), maintaining the 100 Mhz bandwidth. Modules may be connected via the P2 connector to create 8x16, 8x24, 8x32, 8x40, etc. configurations (4 signal highways maximum at P2 with stub disconnect relays), with some decrease in bandwidth. See Application Notes for details.
