Agilent U2722A/U2723A USB
Modular Source Measure Unit
Voltage and current programming
and readback
Data Sheet
The Agilent U2722A/U2723A USB modular source measure unit
is more than just a power supply – it has fast response time, and
voltage and current programming/readback with high accuracy
measurement capabilities. The U2722A and its enhanced version,
the U2723A, are capable of four-quadrant operation, acting as
a current source as well as the current sink (load) with both
polarities of the output voltage. The U2723A offers additional
features such as embedded test scripts to simplify automated
testing, and faster rise time to help improve throughput during
mass testing of semiconductor components.
Introduction

• Four-quadrant operation
(±20 V, ±120 mA)
• Maximum current output of
120 mA per channel
• Embedded test script that is able
to support three channels with
coherent source and measurement
capabilities (for U2723A)
• IV Curve application support in the
Agilent Measurement Manager
software (for U2723A)
• High measurement sensitivity of
100 pA with 16-bit resolution
• 0.1% basic accuracy

USBTMC-USB488 standards
• Standalone and modular
• SCPI and IVI-COM supported
Increase the efficiency of your
tests
With a high measurement sensitivity
of 100 pA at 16-bit resolution for
pico-level measurement and 0.1%
accuracy, the U2722A/U2723A
USB modular source measure unit
provides more detailed and accurate
analysis and measurement results.
U2722A/U2723A supports SCPI and
IVI-COM. The SMU is compatible
with a ride range of Application
Development Environments, minimiz-
ing your work time and increasing
your software options. Save time
and effort with the bundled Agilent
Measurement Manager (AMM) soft-
ware, which coverts SCPI commands
into snippets of VEE, VB, C++ and
C# code with the command logger
function.
Four-quadrant operations with
high measurement sensitivity
and accuracy
The U2722A/U2723A SMU is a
versatile device that allows you to
perform sweep and measurement
from different operating regions
without needing extra configura-
tions. The four-quadrant operation
(±20 V, ±120 mA) makes the
U2722A/U2723A SMU well suited
for a wide range of test applications,
including leakage measurement, solar
cell measurement, forward/reverse
voltage and curve tracer transistors.
The U2722A/U2723A SMU also offers
high measurement sensitivity with
16-bit resolution and accuracy that
allows you to obtain more accurate
analysis and measurement results.
Pre-define test configurations
and execute commands
automatically
The U2723A USB modular source
measure unit provides an embedded
test script to help you pre-define test
configurations or duplicate tests eas-
ily without spending too much time
on programming.
Each channel in the U2723A USB
modular SMU is allocated two
memory lists, each capable of storing
up to 200 commands and results indi-
vidually. Stored commands in active
memory will be executed accord-
ingly while the measurement results
obtained are automatically stored in
the result buffer.

1. Drive 50% of 1 V or 10 V output with a resistive load. Rise time is from 10% to 90% of program voltage change at maximum current.
Fall time is from 90% to 10% of program voltage change at maximum current.
2. Measurements obtained are per default bandwidth setting.
NOTE
• All channels are isolated from the ground and from each other. Isolation is +60 VDC, Category 1.
• All specifications are based on a three-hour warm-up time.
• The measurement accuracy value is x ( 1 + a * y ), where,
◦ x = accuracy specification at room temperature,
◦ a = temperature coefficient, and
◦ y = temperature change from room temperature in °C
