Teledyne LeCroy adds Mixed Signal Capabilities to HDO Oscilloscopes

09 December 2013 - Teledyne LeCroy introduces the HDO4000-MS and HDO6000-MS high definition oscilloscopes which combine 16 channels of flexible mixed signal capabilities with HD4096 high definition technology, long memory, and a compact form factor, in bandwidths from 200 MHz to 1 GHz. All HDO models sport a large 12.1" touch-screen display and intuitive interface to enhance operation.

Powerful debug tools, plus a full complement of automatic measurements, and waveform math capabilities turn the HDO-MS oscilloscope into an all-in-one analog, digital, serial debug machine.

With embedded systems growing more complex, powerful mixed signal debug capabilities are an essential part of modern oscilloscopes. In addition to 16 integrated digital channels, the HDO-MS oscilloscopes ship with a targeted set of digital debug tools. Analog and Digital Cross Pattern Triggering, Digital Timing Measurements, Parallel Pattern Search, Logic Gate Emulation and Activity Indicators are the ideal tools for precise circuit validation and fast debugging of complex embedded designs. These features complement the comprehensive HDO toolset which includes WaveScan search and find, history mode waveform playback, sequence acquisition mode, and LabNotebook report generation. Spectrum-analysis and power-measurement software packages extend the oscilloscopes' capabilities while leveraging the 12-bit architecture with its wider dynamic range and improved measurement precision.

HDO4000-MS oscilloscopes feature a sample rate of 2.5 GS/s with up to 25 Mpts/channel of memory (up to 50 Mpts/ch when interleaved) in two- and four-channel models from 200 MHz to 1 GHz. The HDO6000-MS oscilloscopes are available in four-channel models and deliver sample rates of 2.5 GS/s; a maximum 250-Mpts/channel memory, and bandwidths of 350 MHz, 500 MHz, and 1 GHz.

HD4096 High Definition Technology

HD4096 High Definition Technology is rooted in high-sample-rate 12-bit ADCs; amplifiers with high signal-to-noise ratios; and a low-noise system architecture. This technology enables high definition oscilloscopes to capture and display signals of up to 1 GHz with high sample rate and 16 times more resolution than other oscilloscopes. Precise measurements are critical for effective debug and analysis. HD4096 enables oscilloscopes to deliver unmatched measurement precision to improve testing capabilities and provide better results.

In addition to HD4096 technology, the HDO features Teledyne LeCroy's ERES (Enhanced Resolution) filtering, which enables users to gain up to three additional bits of resolution for 15-bit vertical resolution.

Advanced Measurement, Debug, and Analysis

Accurate signal display and high sampling rates go to waste in the absence of superlative debug and analysis tools. All HDO oscilloscopes contain powerful tools for fast debug and deep waveform analysis. The WaveScan advanced search and find tool, which allows searching a single acquisition for runts, glitches, and other anomalies using more than 20 different criteria, can also be used to set up a scan condition and search for an event for hours or even days. History mode permits scrolling back in time to isolate anomalies and measure them with parameters or cursors. Serial trigger and decode functionality quickly isolates bus events without the need to set manual triggers. Sequence mode stores triggered events as "segments," enabling capture of many fast pulses in quick succession or events separated by long periods of time, reducing dead time between triggers. The LabNotebook documentation and report generation tool makes quick work of saving and documenting test results.

With math functions including averaging, enhanced resolution and FFT plus a wide variety of measurement parameters, the HDO can measure and analyze every aspect of a waveform. Beyond just measuring waveforms, statistics, histograms and measurement trends show waveform changes over time.

Spectrum Analyzer and Power Analysis Software

Also available for the HDO are software packages that serve to sharpen the instruments' focus on two key analysis areas that affect a broad range of design and debug tasks. The Spectrum Analyzer software converts the controls of an HDO into those of a spectrum analyzer. It enables users to adjust the frequency span, resolution bandwidth, and center frequency. Users can apply filters to input signals and watch the frequency signature change in real time. A unique peak search labels spectral components and presents frequency and level in a table. Users may touch any line to move to that peak. They can use the spectrogram display to see how the spectrum changes over time.

The Power Analysis software option quickly measures and analyzes the operating characteristics of power conversion devices and circuits with automatic loss measurements and a dedicated user interface. Areas of turn-on, turn-off and conduction loss are identified with color coded waveform overlays. Tools for performing critical power switching device measurements, control loop modulation analysis, and line power harmonic testing are all built in.
