The OMSP-4000 Series has been discontinued. Please see the HOS-MS6200 Series or the BOS Series as
possible alternatives or contact our Data Acquisition Engineering Department.
The new OMSP-4000 Series offers the highest performance available
from any USB-powered oscilloscope on the market today.
The OMSP-4000 Series has the power to perform in many applications, such
as design, research, test, education, service and repair. These USBpowered
oscilloscopes are also small, light and portable. They easily
slip into a laptop bag making them ideal for the engineer on the move.
There is no need for an external power supply, making them ideal for
field use.
High Bandwidth, High Sampling Rate
Models OMSP-4224 and OMSP-4227 have bandwiths of 20 MHz
and 100 MHz respectively with sampling rate up to 250 MS/s. ETS
mode boosts the maximum effective sampling rate further to 10 GS/s,
allowing more detailed display of repetitive signals.
Huge Buffer Memory
The OMSP-4000 Series offers memory depths up to 32 million
samples. Other oscilloscopes have high maximum sampling rates,
but without deep memory they cannot sustain these rates on long
timebases. The OMSP-4227 can sample at 100 MS/s at timebases all
the way down to 50 ns/div. Managing all this data calls for
some powerful tools, so the OMEGASCOPE software
has a maximum zoom factor of 100 million combined with
a choice of two zoom methods. There’s a conventional set of zoom
controls, plus an overview window that shows you the whole waveform
while you zoom and reposition the display by simply dragging with the
mouse. Another use for the huge memory is our segmented memory. Each
captured waveform is stored in the buffer so you can rewind and review
thousands of previous waveforms. No longer will you see a glitch on
the screen only for it to vanish before you stop the scope.
Advanced Triggers
As well as the standard range of triggers found on all oscilloscopes,
the OMSP-4000 Series offers a class-leading set of advanced
triggers including pulse width, windowed and dropout triggers to
help you capture the data you need.
Digital Triggering
Most digital oscilloscopes sold today still use an analog trigger
architecture based around comparators. This can cause time
and amplitude errors that can not always be calibrated out. The use
of comparators often limits the trigger sensitivity at high bandwidths
and can also create a long trigger “re-arm” delay. OMSP-4000 Series
oscilloscopes use full digital triggering using the actual digitized
data. This reduces trigger errors and allows our oscilloscopes to trigger
on the smallest signals, even at the full bandwidth.
Trigger levels and hysteresis can be set with great precision and
resolution. Digital triggering also reduces re-arm delay and this
combined with the segmented memory allows the triggering
and capture of events that happen in rapid sequence. At
the fastest timebase you can use rapid triggering to collect 10,000
waveforms in under 20 milliseconds. Our mask limit testing function can
then scan through these waveforms to highlight any failed waveforms for
viewing in the waveform buffer.
Custom Probe Settings
The custom probes feature allows you to correct for gain, attenuation,
offsets and nonlinearities in special probes, or to convert to different
units of measurement (such as current, power or temperature). You
can save definitions to disk for later use. Definitions for standard supplied
oscilloscope probes and current clamps are included.
Arbitrary Waveform and Function Generator
Model OMSP-4227 has a built-in function generator (sine, square,
triangle, DC level). As well as basic controls to set level, offset and
frequency, more advanced controls allow you to sweep over a range
of frequencies. Combined with the spectrum peak hold option this
makes a powerful tool for testing amplifier and filter responses.
The OMSP-4227 also includes a full arbitrary waveform generator.
Waveforms can be created or edited using the built-in AWG editor,
imported from oscilloscope traces, or loaded from a spreadsheet.
Spectrum Analyzer
With the click of a button, you can display a spectrum plot of the
selected channels. The spectrum analyzer allows signals up to 200
MHz to be viewed in the frequencydomain. A full range of settings
gives you control over the number of spectrum bands, window types
and display modes: instantaneous, average, or peak-hold. You can
display multiple spectrum views with different channel selections and zoom
factors, and OMEGASCOPE allows you to see these alongside timedomain
waveforms of the same data. A comprehensive set of automatic
frequency-domain measurements, including THD, THD+N, SNR, SINAD
and intermodulation distortion, can be added to the display.
Math Channels
The OMSP-4000 Series oscilloscopes offer a full range of
math functions for processing and combining channels. The functions
can also operate on reference waveforms. Use the built-in list for
simple functions such as addition and inversion, or open the equation
editor and create complex functions involving trigonometry, exponentials,
logarithms, statistics, integrals and derivatives.
Advanced Display Modes
See old and new data superimposed, with new data in a brighter color or
shade. This makes it easy to see glitches and dropouts and to estimate
their relative frequency. Choose between analog persistence and
digital color, or create a custom display mode. The design of the
OMEGASCOPE software ensures that maximum display area is
available for waveform viewing. Even with a laptop you have a much
bigger viewing area and higher resolution than a typical benchtop scope.
Serial Decoding
The OMSP-4000 Series with its deep memory is ideal
for serial decoding as it can capture thousands of frames of
uninterrupted data. Protocols currently included are I²C, SPI,
RS232, UART and CAN bus. Expect this list to grow with free software
updates. OMEGASCOPE displays the decoded data in the format of
your choice: “in view”, “in window”, or both at once. The “in view” format
shows the decoded data beneath the waveform on a common time
axis, with error frames marked in red. You can zoom in on these
frames to look for noise or distortion on the waveform. “In window” format
shows a list of the decoded frames, including the data and all flags and
identifiers. You can set up filtering conditions to display only the frames
you are interested in, search for frames with specified properties,
or define a start pattern that the program will wait for before listing
the data. You can also create a spreadsheet to fully decode the hex
data into plain text.
Mask Limit Testing
This feature is specially designed for production and debugging
environments. Capture a signal from a known working system,
and OMEGASCOPE will draw a mask around it with your specified
tolerance. Connect the system under test, and OMEGASCOPE will
highlight any parts of the waveform that fall outside the mask area.
The highlighted details persist on the display, allowing the scope to
catch intermittent glitches while you work on something else. The
measurements window counts the number of failures, and can display
other measurements and statistics at the same time. The numerical
and graphical mask editors can be used separately or in combination,
allowing you to enter accurate mask specifications and to modify existing
masks. You can import and export masks as files.
High-End Features as Standard
With the OMSP-4000 Series, “high end” features such as mask limit
testing, serial decoding, advanced triggering, measurements, math,
XY, digital filtering and segmented memory are all included standard.
To protect your investment, both the PC software and firmware inside the
unit can be updated.
High Signal Integrity
Careful front-end design and shielding reduces noise, crosstalk
and harmonic distortion. Years of oscilloscope experience leads
to improved pulse response and bandwidth flatness. The result is
simple: when you probe a circuit, you can trust in the waveform you
see on the screen.
