34925A Simplified Schematic for One-Wire Mode

This drawing shows two independent 40- channel, 1- wire MUXes. To
change configuration modes, use the SYSTem:MODule:WIRE:MODE
command.
NOTE: The three-digit number assigned
to each switch represents the channel
number.
NOTE:
Bank relays: FET non-latching
Analog Bus relays: Armature non-latching
