2.1 Cables
The B2900A series has banana type output ports with Force, Sense and Guard potential.
However, if you use conversion adapter, you can use BNC type cables or Triaxial cables so
that each SMU channels can connect to dedicated test environment for DUT such as test
fixture or wafer prober. The great variety of available cables can be categorized into mainly
five types:
• Banana Test Lead - To simplify the connections, you can use 2-wire connections or
4-wire connections by using banana test leads for connection of DUT. There are many
types of DUT interface.
• BNC cables - Co-axial type cables. Central signal line is surrounded by shield
potential. However, this is not suitable for ultra low current measurement below nA
level. For these low current measurements, we recommend to use the following
Triaxial cables.
• Triaxial cables - have three leads - a central conductor for the signal, an encapsulating
conductor that shields the center signal by employing the same voltage thus decreasing
a possible leakage current - and an outer conductor that serves as Common. To use this
cable, Banana to Triaxial adapter is required.

Model/Option Description Additional Information
U8201A Combo Test Lead Kit
Couple of test leads, test probes, alligator clips, SMT
grabbers, fine-tips test probes, and banana plugs, CAT III
1000 V, 15 A maximum
Two kits are required for the 4-wire connections.
11059A Kelvin Probe Set
This kelvin probe set consists of two gold-plated flat
tweezers with special gripping surfaces. This design
assures a very precise contact to the component and very
precise measurements. The ground guard connector
removes ground-related errors.
• Maximum voltage : 42 V
• Termination : 5 signal banana plugs (4-wire
measurement plus ground)
• Cable Length : 0.8 m (31.5 inches)
