1 INPUT
This standard three-lug female triax connector is used to connect the signal to be measured to the input
of the Model 6487. Mates to a three-slot male triax connector cable.
2 CHASSIS
This screw terminal is used to connect COMMON to CHASSIS ground via the ground link connector.
3 COMMON
This standard banana connector can be used as input LO or as the common for the ANALOG OUT.
Also can be used as a ground link. Note that there is a 1k(ohm) resistance to input LO from the
ANALOG OUT common.
4 ANALOG OUT
This standard banana connector provides a scaled, inverting output (inverting 2V full scale on all
ranges).
