Digital Storage Oscilloscopes 2550 Series Data Sheet規格參數指標
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.

The tools you need
Display and measure the input signal’s frequency spectrum. Select
one of the 4 FFT windows: Rectangular, Hanning, Hamming, and
Blackman. Use cursors to measure the spectral component’s
magnitude and frequency.
Monitor and analyze long-term signal behavior by recording data
continuously over an extensive period of time and playing it back for
post acquisition analysis. Data is recorded in a sequence of up to
2500 frames.
Minimize debug time by saving and recalling setups and waveforms
from internal memory. Save and recall up to 20 different oscilloscope
setups and 20 different waveforms.
Filter out unwanted signal components such as various types of noise
with built-in digital filters. Choose from Low-Pass, High-Pass,
Band-Pass, and Band-Stop filters.
Generate user-defined pass/fail limits to quickly identify go/no go
test results.
Use the oscilloscope’s delayed sweep feature to zoom in a particular
area of a signal in real time while viewing the entire captured
waveform simultaneously.
Powerful measurement functions Digital filtering
Waveform recorder Delayed sweep/zoom
Large internal storage Pass/Fail testing

PC connectivity
Avoid limiting the bandwidth of your measurement system. All 2550 series models come standard with
high bandwidth, slimline passive probes (one per channel) to help you get the most out of your scope.
PC software is provided (free download at B&K
Precision’s website at www.bkprecision。。ｃｏｍ) for
seamless integration between the oscilloscope
and PC. Capture and transfer waveforms, screen
images, setups and measurement results to a
Windows PC via the USB device port on the
back of the instrument. A USB host port on the
front and rear allows for quick and easy screen
saving.
