44478A Simplified Schematic
A simplified schematic is shown below. The two groups of 4-to-1 MUXs
are specified as GROUP 00 and GROUP 10. They are isolated from each
other. Closing a channel closes a particular set of relays to connect the
common BNC to one of the four BNC inputs. Channels within each group
are break-before-make and are numbered as 00 through 03 for GROUP
00 and 10 through 13 for GROUP 10.
