The 2540B, 2542B, 2540B-GEN, and
2542B-GEN dual channel 60 MHz and 100
MHz digital storage oscilloscopes deliver
performance and value, all in one portable
solution. Maximize productivity using extensive
features such as digital filtering, waveform
recorder, pass/fail limit testing, and automatic
measurements. These oscilloscopes offer
powerful tools in a small affordable package with
deep waveform memory up to 2.4 Mpts plus
LAN and USB PC interface. The 2540B-GEN
and 2542B-GEN models add a built-in
function/arbitrary waveform generator (AWG).
Easily capture, save, and analyze measurement
results with Comsoft PC software. All scope
parameters can be controlled via a PC without
the need for programming or communicate with
the DSO via the built-in LAN interface using a
web browser.
Additionally, these oscilloscopes can be integrated
with AWGs using B&K Precision's waveform
editing software, WaveXpress. WaveXpress allows
users to easily modify waveforms downloaded
from the scope and can also be used for analysis
of deep memory acquisitions.
Educators will appreciate the ability to disable the
Auto Set button that would automatically setup
the scope to display a signal, circumventing the
need to know how to set up scope parameters.
This is key for teaching waveform measurement
fundamentals as if it was an analog oscilloscope.
These oscilloscopes are ideal for applications in
design and debugging, service and repair, and
education.

De ep Memor y
The built-in LAN interface allows you to easily
capture screenshots at a user-configurable
refresh rate with a web browser. A GUI simulat-
ing the front panel provides full DSO control.
This feature can be useful in an education
setting.
Comsoft software provides seamless integration
between the oscilloscope and PC. Capture and
transfer waveforms, screen images, setups, and
measurement results to a Windows PC via the
LAN and USB device port on the back of the
instrument. A USB host port on the front allows
for quick and easy screen saving to a USB flash
drive.
Beneficial for applications such as I C serial data
streams, deep memory lets you capture wave-
forms in high resolution while maintaining a high
sample rate over a longer period of time. Up to
2.4 Mpts of memory can be captured in as fast
as 5 seconds
*
using binary transfer through the
LAN or USB interface.
*Typical time based on LAN speed testing.

intuitive Comsoft PC software.
Quick and easy single-button capture func-
tion lets you acquire and store your signal
directly from the oscilloscope’s channels to
the generator’s internal memory. Not only
can CH1 and CH2 signals be captured, but
math functions applied to the channels can
also be captured and stored.
Display a graphical illustration explaining the
parameters of the built-in arbitrary waveforms
and modulation schemes. This is a convenient
tool for students and new users.
Wide Array of Modul ation Sche mes
Remotely connect to the scope and
download waveform data from custom
software using SCPI commands.
30 Built-In Arbitrary W avefor ms
Store user arbitrary waveforms internally (up to
10 waveforms) or externally as an ARB or CSV
file to a USB flash drive.
The built-in arbitrary waveform generator is
capable of many different types of modulation for
various applications. Modulate your waveforms
with AM, FM, FSK, PSK, and PWM modulation
schemes and use any of the 30 built-in wave-
forms as the modulating waveform.
Take advantage of the generator’s already
built-in waveforms that fit your application.
