These handy, economical
oscilloscopes have all the power you
need for your application, whether
it’s design, research, test, education,
service or repair. They are available
with bandwidths from 10 to 25 MHz.
OMSP-2000 Series oscilloscopes are
small, light and portable. They easily
slip into a laptop bag and so are ideal
for the engineer on the move. They
don’t need an external power supply,
so they are perfect for field use. The
connection to your PC means that
functions such as printing, copying and
email are always at your fingertips.
Digital Triggering
that happen in rapid
sequence. At the
fastest timebase, rapid
triggering can capture
a new waveform every 2
microseconds until the buffer
is full. The mask limit testing
feature (see next page) helps to
detect waveforms that fail to meet
your specifications.
Advanced Triggers
As well as the standard range of
triggers found on all oscilloscopes,
the OMSP-2000 Series offers one
of the best selections of advanced
triggers available, including pulse
width, windowed and dropout triggers
to help you find your signal quickly.

and Function Generator

Custom Probe Settings
Most digital oscilloscopes sold today
still use an analog trigger architecture
based on comparators. This can
cause time and amplitude errors that
cannot 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-2000 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.The reduced
re-arm delay provided by digital
triggering, together with segmented
memory, allows the capture of events
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 built in.
All units have a built-in function
generator with sine, square, triangle,
DC level and many more standard
waveforms. As well as level, offset
and frequency controls, more
advanced options allow you to
sweep over a range of frequencies.
Combined with the spectrum peak
hold option, this creates a powerful
tool for testing amplifier and filter
responses. The OMSP-2000 Series
scopes also include 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
Measurements
You can add any combination of automatic measurements to the
display, chosen from a list of 26 scope and spectrum parameters. Every
measurement includes statistics of minimum, maximum, average,
standard deviation and sample size.
With the click of a button, you can
display a spectrum plot of selected
channels. The spectrum analyzer
allows signals up to the full scope
bandwidth to be viewed in the
frequency domain. A full range
of settings gives you control over
the number of spectrum bands,
window types and display modes:
instantaneous, average, or peakhold. The OMEGASCOPETM software
allows you to display multiple
spectrum views with different channel
selections and zoom factors, and
see these alongside time-domain
waveforms of the same data. A
comprehensive set of automatic
frequency-domain measurements,
including THD, THD+N, SNR, SINAD
and IMD, can be added to the display.
Math Channels
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.
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 decode the
hexadecimal data into arbitrary
text strings.
Mask Limit Testing
The OMSP-2000 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.

Serial Decoding
The OMSP-2000 Series includes
serial decoding capability as
standard. Protocols currently
included are I²C, SPI, RS232/UART
and CAN bus. Expect this list to
grow as we release 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
This feature is specially designed
for production and debugging
environments. Capture a signal from
a known working system, and the
OMEGASCOPE software 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 modify existing
masks. You can import and export
masks as files.

The OMEGASCOPE Window
Oscilloscope Controls: Commonly-used controls
such as voltage range selection, timebase, memory
depth and channel selection are placed on the
toolbars for quick access, leaving the main display
area clear for waveforms. More advanced controls and
functions are located in the Tools menu.
Auto Setup Button: Configures the timebase and
voltage ranges for stable display of your signals.
Tools>Math Channels: Combine input channels
and reference waveforms using simple arithmetic, or
create custom equations with trigonometric and other
functions.
Tools>Serial Decoding: Decode a serial data signal
and display the data alongside the physical signal or
as a detailed table.
Tools>Reference Channels: Store waveforms in
memory or on disk and display them alongside live
inputs. Ideal for diagnostics and production testing.
OMEGASCOPE: The display can be as simple or as
complex as you need. Begin with a single view of one
channel, and then expand the display to include any
number of live channels, math channels and reference
waveforms.
Waveform Replay Tool: OMEGASCOPE
automatically records up to 10,000 of the most recent
waveforms. You can quickly scan through to look for
intermittent events.
Views: OMEGASCOPE is carefully designed to
make the best use of the display area. You can add
new scope and spectrum views, all of which are fully
adjustable in size and shape.
Rulers: Each axis has two rulers that can
be dragged onto the screen to make quick
measurements of amplitude, time and frequency.
Zoom and Pan Tools: Use the conventional
zoom buttons, or try the zoom overview window
for fast navigation. No fiddly buttons and knobs:
just use your mouse!
Movable Axes: The vertical axes
can be dragged up and down.
This feature is particularly useful
when one waveform is obscuring
another. There’s also a command to
rearrange all the axes automatically.
Automatic Measurements: Display
calculated measurements for
troubleshooting and analysis. You
can add as many measurements
as you need on each view. Each
measurement includes statistical
parameters showing its variability.
Mask Limit Testing:
Automatically generate a test
mask from a waveform or draw
one by hand. OMEGASCOPE
highlights any parts of the
waveform that fall outside the
mask and shows error statistics.
