Data Sheet
Digital Storage Oscilloscopes
2550 Series
The 2550 series digital storage oscilloscopes
provide high performance and value in 2-channel
and 4-channel configurations. With bandwidth
from 70 MHz to 300 MHz and 2 GSa/s sample
rates, these oscilloscopes offer 24 kpts/Ch
waveform memory, 32 automatic measurements,
and advanced triggering capabilities including
math functions. Engineered to allow you to see
more of your signal under test, the 2550 series’
widescreen 7” TFT display offers a significantly
larger viewing area than typical economy
oscilloscopes (5.7”).
Maximize productivity with PC connectivity via
LAN and USB. The downloadable PC software
lets you easily capture, save, and analyze
measurement results. All oscilloscope parameters
can be controlled via a PC without the need for
programming.
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 who want to teach waveform
measurement fundamentals can benefit from
the ability to disable the Auto set button, a
function that automatically sets up the scope
to display a signal.
The 2550 series oscilloscopes are ideal for
applications in design and debug, service and
repair, and education.
