Description

The OMSP-2000 Series has been discontinued. Please see the HOS-MS6200 Series or the BOS Series as possible alternatives or contact our Data Acquisition Engineering Department.

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
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 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.

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 built in.

Arbitrary Waveform and Function Generator
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
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
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.

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-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 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
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.

High-End Features as Standard
With the OMSP-2000 Series, high-end features such as resolution enhancement, mask limit testing, serial decoding, advanced triggering, automatic measurements, math channels and XY mode 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 and provide 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.
