DUAL-PLAY — standalone and
modular capability
Compatibility with wide range of
application development
Highest performance, lowest cost for today and
Agilent’s U2701A and U2702A USB
modular oscilloscopes combine a set
of essential features that are ideal for
analyzing designs in an affordable way.
The U2701A and U2702A come in
two bandwidths: 100 MHz and 200
MHz respectively. These devices are
uniquely designed to accommodate
your needs for flexibility with the dualplay function. Dual-play functionality
allows you to use the oscilloscope as
a standalone or to scale up the test
system in a cardcage with additional
scopes or with Agilent’s other USB
modular product offerings, thus
providing a complete solution for
system development.
The U2701A and U2702A give you
the debugging power you need. Each
modular oscilloscopes comes standard
with features such as advanced
triggering, automatic measurements,
math functions including FFTs, and
much more.
The user-friendly Agilent Modular
Instrument Measurement Manager
software bundled with the U2701A
and U2702A offers a simple interface
for quick setup, configuration, and
measurement control.
Why Do You Need Deep
Memory and a High
Sampling Rate?
To see more time
When you are able to store more
samples that you have obtained in
the memory, you can view the signal
at a longer time. This will be the best
way to understand the use of deep
A longer capture time gives you a
better visibility into cause-effect
relationships in your designs, which
significantly simplify your root-cause
debugging. It also allows you to
capture start-up events in a single
The need to stitch together multiple
acquisitions or set precise triggering
conditions are no longer necessary.
You can spend less time finding
events, and more time analyzing them.
To see even more details
The relationship between memory
depth and acquisition rate is not as
obvious. All scopes have a “banner”
maximum sample rate specification,
but many can only sustain these rates
at a few time base settings.
Higher sampling rate
By offering sampling rate more than
twice the acquired signal bandwidth,
aliasing can be prevented. With
more sampling data captured, higher
accuracy of your test and analysis
results can be achieved.
Figure 2 The dual-play capability allows U2701A and U2702A USB modular
oscilloscopes to be used as standalone units or fitted into a cardcage.
Compatible with a Wide Range of Application
Development Environments
The Agilent U2701A and U2702A USB modular oscilloscopes are compatible
with a wide range of application development environments. This minimizes the
time that R&D and manufacturing engineers need to use the devices in different
software environments.
Listed below are the popular development environments and tools with which
the USB modular oscilloscope is compatible:
• Agilent VEE and Agilent T&M Toolkit
• Microsoft Visual Studio.NET, C/C++ and Visual Basic 6
• Microsoft .NET Framework
Ease of Use
The U2701A and U2702A USB modular
oscilloscopes are equipped with HiSpeed USB 2.0 interface for easy setup
and plug-and-play. Hence, this ease-ofuse makes the oscilloscopes ideal for
the education, design validation, and
manufacturing environment.

Features you need
The U2701A and U2702A include the
following standard features that you
need to do your job done quickly and
Hi-Speed USB Interface
The U2701A and U2702A connect to
the computer through Hi-Speed USB
2.0 connectivity.
Autoscale lets you display any
active signals, automatically setting
the vertical, horizontal, and trigger
controls for the best signal display
within the shortest time.
High sampling rate
Sampling rate up to 500 MSa/s/ch
enables more details of the signal
to be seen and analyzed. When two
channels are interleaved, the sampling
rate can be up to 1 GSa/s. This fastsampling capability allows you to
perform intermittent detection easily.
Pulse triggering
Pulse triggering allows you to trigger
on pulse events.
Advanced triggering
Edge, pulse width, and TV are the
triggering modes included to help you
isolate the signals you want to see.
The U2701A and U2702A’s compact
size makes them portable and easy to
be carried to your working field.
Large memory
With memory depth up to 32 Mpts,
you can capture even more data.
Larger memory allows you to capture
data over a longer time frame.
One-year warranty
Every U2701A and U2702A comes with
one year warranty.
Fast Fourier Transfer (FFT) and
Waveform Math
The U2701A and U2702A offer
analysis functions such as addition,
subtraction, multiplication, division,
and Fast Fourier Transform (FFT).
FFT allows you to manipulate
the waveform using five types of
windows such as Hanning, Hamming,
Blackman-Harris, Flattop, and
Figure 4 The U2701A and U2702A connect to the computer or laptop with a USB
cable, enabling fast data transfer.

All characteristics are typical performance values and are not warranted. Characteristics are valid after a 30-minute warm-up
period and within ±10ºC of last calibration temperature.
Under standalone use, users are only allowed to measure up to CAT1 30 Vrms. For high-voltage measurement up to
CAT1 300 Vrms, users must install the L-mount kit on the U2701A/U2702A before plugging into the instrument chassis. Ensure
that the L-Mount kit installed on your modular oscilloscope is screwed to the instrument chassis to ensure chassis grounding. It is
required to use the provided 10:1 probes (N2862A/N2863A) for high-voltage measurements
