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
