BITE:
Read-back  capability  of  all  relay
driver states provides system check
of  entire  board  except  for  relay
contacts.

The HF4x8 is a VMEbus compatible
100  Mhz  switching  matrix  with

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

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.
