Description

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.
