To Connect the SMU Output
The following figures show connection examples for the SMU output.
Kelvin connections non-Kelvin connections
This connection is for the 4156C HRSMU or
the 41501A/B HPSMU.
Use low-noise coaxial cable (Agilent part
number 8121-1191) from the connector to
the prober, socket, or DUT as shown.
To cancel the effects of cable resistance,
connect the Sense line and Force line as close
as possible to the DUT terminal.
To prevent oscillations, do not use cables
longer than 1.5 m.
To make accurate measurements when
applying high currents, extend the guard as
far as possible from the front panel connector
to the DUT. Physically stabilize the cables
with tape.
The following figure is for the
HRSMU/HPSMU connection using Kelvin
triaxial cable. For the MPSMU connection,
and for the HRSMU/HPSMU connection
using triaxial cable, connect the cable to the
Force terminal only. Measurement data will
include residual resistance from the
connection cable.
Use low-noise coaxial cable (Agilent part
number 8121-1191).
To make accurate measurements when
applying high currents, extend the guard as
far as possible from the front panel connector
to the DUT.
