Introduction
The Keysight Technologies, Inc.
B2901A/02A/11A/12A Precision Required Instrument and Accessories
Source/Measure Units are compact
and cost-effective bench-top Source/ Keysight 11059A Kelvin Probe Set and Resistors are equipped as a demo kit
Measure Units (SMUs) with the with a demo unit of the Keysight B2900A Series of SMU.
capability to output and measure
both voltage and current. The
B2901A/02A/11A/12A enables you
to make a wide range of current
versus voltage (IV) measurements
more accurately and quickly
than ever before. In addition, the
B2901A/02A/11A/12A comes with
an intuitive graphical user interface
(GUI) and free PC-based application
software that make it easy for you to
begin making productive measure-
ments immediately.

This demonstration guide shows how Precision Source/Measure Unit
easily basic resistance measurement
can be made using the Keysight
B2901A/02A/11A/12A.
The demonstration includes not only
a simple resistance measurement 1 Resistor
using 2-wire connection, but also a
low resistance measurement using
4-wire connection.

Why is 4-wire connection required?
For very low resistance measurements where the residual lead resistance is
comparable to the DUT resistance, the 2-wire measurement will give erroneous
measurement results. In this case a 4-wire connection scheme (remote sensing)
can be used to eliminate this error. A 4-wire measurement uses one pair of leads
to force current and the other pair of leads to monitor voltage. This eliminates
cable resistance effects so that only the voltage drop across the DUT is measured.
