SENSE terminal
The SENSE terminal is a standard triaxial connector used to apply the ground unit SENSE signal
to the DUT in a remote sense application.
• The center pin is SENSE
• The inner shield is GUARD
• The outer shield is circuit COMMON
When the ground unit SENSE signal is connected to a DUT, all SMU/preamp measurements will
be made relative to this DUT connection.
COMMON terminal
The COMMON terminal is a binding post that provides access to circuit COMMON.
NOTE Normally, a link is connected between ground unit COMMON and chassis ground,
but it may be necessary to remove the link to avoid measurement problems caused
by ground loops or electrical interference. Refer to the Reference Manual,
Interference, page 5-25 for details.
Chassis ground
This binding post provides a convenient connecting point to system chassis ground for the
purpose of shielding a test fixture.
