New 200 MHz to 1 GHz Oscilloscopes

03 February 2011 - LeCroy announced a new line of WaveSurfer MXs-B and MSO MXs-B oscilloscopes ranging from 200 MHz to 1 GHz bandwidth. The oscilloscopes deliver sample rate of up to 10 GS/s and memory of 25 Mpts. They feature debug tools such as WaveStream Fast Viewing Mode, WaveScan Search and Find, a wide variety of serial data trigger and decode packages plus the LabNotebook documentation and report generator.

The MSO MXs-B models provide 18 digital channels that can sample at 1 GS/s for debugging analog and digital mixed signal systems. WaveSurfer uses a big 10.4" color display to allow room for time-correlated views of mixed-signal systems and non-time domain analysis.

Sequence mode is a versatile acquisition mode that segments the oscilloscope memory and combines up to 10,000 acquisitions in to a single, sequential waveform. This technique enables capturing of very fast pulses in rapid succession with trigger rates of up to 1.25 million waveforms per second.

Additionally, Sequence Mode can be used to optimize memory usage by only capturing data when data is present, ignoring large spans of dead time between pulses or bursts. In the end all the waveforms are displayed and time stamped for further analysis.

WaveScan provides the ability to locate unusual events in a single capture (i.e., capture and search), or “scan” for an event in any acquisitions over a long period of time. Users can select from more than 20 search modes (frequency, rise time, runt, duty cycle, etc.), apply a search condition and begin scanning. Since the scanning “modes” are not simply copies of the hardware triggers, the utility and capability is much higher. For instance, there is no “ frequency” trigger in any oscilloscope, yet WaveScan allows “frequency” to be quickly “scanned” for. This allows the user to accumulate a data set of unusual events that are separated by hours or days, enabling faster debugging.

An all-in-one solution for annotating and sharing information, LabNotebook simplifies results recording and report generation by eliminating the multi-step processes that often involve several pieces of equipment. Users can add freehand notes with a stylus or as text and convert the complete report to pdf, rtf, or html.

The serial data trigger and decode options for WaveSurfer provide time saving tools for serial bus debug and validation. The serial data trigger will quickly isolate events on a bus eliminating the need to set manual triggers. Protocol decoding is shown directly on the waveform with an intuitive, color-coded overlay and presented in binary, hex or ASCII. Decoding on the Wavesurfer is fast, even with long memory, and zooming in to the waveform shows precise byte-by-byte decoding. To further simplify the debug process, all decoded data can be displayed in a table below the waveform grid. Selecting an entry in the table with the touch screen will display just that event. MSO MXs-B and the WaveSurfer MXs-B offer tools for trigger and decode of a broad set of popular serial data signals such as I2C, SPI, UART, CAN, LIN, FlexRay, USB, ARINC 429, MIL-STD-1553, MIPI D-PHY, DigRF3G, and Digital Audio.
