Auxiliary Output Connection
An undedicated isolated auxiliary output is provided to power various actuators and circuits local to the
test fixture. It can also be used as the pull-up source for any digital I/O connections that require an
external pull-up source. The auxiliary output is available through a 4-pin Phoenix/Weidmuller style
connector on the rear panel. The connector has screw terminals for making wire connections and is
detachable.
As explained in chapter 3, the Agilent MCCD Configuration Screens let you set this output to between 5
volts and 24 volts in 0.1-volt increments. 10 Watts of total output power is available. The auxiliary
output is isolated by up to 42 volts with respect to chassis common (earth ground).
