Accessories for the B1500A
CAUTION The GNDU can sink current of up to 4.2 A. Use the Agilent 16493L GNDU cable to
connect the GNDU to a test fixture or a connector plate.
Do not use normal triaxial cable (Agilent 16494A), because the maximum current rating of
the cable is 1 A.
NOTE For the lower current measurement, use the 16494A Triaxial cable with low-noise
environment. This cable can maximize the guard effects and minimize the impression of
the external noise.
2.1.2 CMU accessories
• CMU cables - have BNC type. Accurate capacitance measurement requires dedicated
cables so that cable can be compensated. B1520A MFCMU has very thin module
design, so 16048D/E cannot connect with B1500A.
• SCUU (SMU CMU unify unit) - is used to switch the module (CMU or SMU) to be
connected to the DUT. The SCUU is available for the MPSMU and HRSMU.
• GSWU (Guard switch unit) - is used to connect the CMU high and low guard lines
together near the DUT. The connection is broken when the SCUU is in the SMU
connection state. The GSWU is effective for the accurate impedance measurement.
