Multiple Smu Connections - Keithley 2601B Reference Manual

Series 2600B System SourceMeter® Instrument Reference Manual Section 2: General operation

Multiple SMU connections

Carefully consider and configure the appropriate output-off state, source, and compliance limits
before connecting the Series 2600B to a device that can deliver energy (for example, other voltage
sources, batteries, capacitors, solar cells, or other Series 2600B instruments). Configure
recommended instrument settings before making connections to the device. Failure to consider the
output-off state, source, and compliance limits may result in damage to the instrument or to the
device under test (DUT).
The following figures show how to use the SMUs of two Series 2600B instruments to test a 3-terminal
device, such as an N-channel JFET (see TSP advanced features (on page 6-53) for information on
using multiple Series 2600B instruments). A typical application is for a Series 2600B to source a
range of gate voltages, while the another Series 2600B sources voltage to the drain of the device and
measures current at each gate voltage.
