Current-boosted output, 5725A
16-gauge or heavier twisted pair insulated wire,
as short as possible to minimize resistance and
inductance. (Output is at the amplifier terminals.)
Current-boosted output, 52120A
Refer to the 52120A manual for cable
requirements.
[1] Spade lugs provide a slightly better thermal EMF performance. However, some UUTs have repressed
banana connectors that cannot accommodate spade lugs.
