SAN JOSE, Calif. – LeCroy has added 12-bit resolution oscilloscopes to its WaveRunner family. The WaveRunnerHRO 6 Zi range has 400 MHz and 600 MHz models.
The HRO stands for high resolution oscilloscopes and they use 12-bit and analog to digital convertor (ADC) and have deep memory of up to 256 Mpts/ch with 64 Mpts/ch standard.
These features are added to the existing analysis capabilities of the WaveRunner 6 Zi Series (400 MHz to 4 GHz) which was launched in February 2011.
Designed for the medical, automotive, and electro-mechanical markets the scopes make use of reduced noise and improved resolution of the 12-bit ADC architecture to provide finer measurement accuracy and better waveform clarity. This can be seen with the 55 dB signal-to-noise-ratio (SNR) and ± 0.5% DC vertical gain accuracy; which LeCroy says is four times more precise than 8-bit oscilloscopes.
The 256 Mpts/ch deep memory capability permits long acquisitions to capture 30 seconds of data sampled at 10 MS/s, or shorter capture times with the highest resolution at 2 GS/s. This performance is augmented by a offset and timebase delay adjustment to ease signal and amplifier performance assessment and zooming on vertical and horizontal signal characteristics.
LeCroy is using the same pivoting display used in the WaveRunner 6 Zi - a video of this in operation was captured at Embedded World.
This that permits viewing signals vertically as well as horizontally to obtain more detail for optimal analysis. This is an advantage particularly when viewing up to 36 channels using the mixed signal option, when operating in the frequency domain using the spectrum analysis package, or when viewing decoded waveforms using the selection of tools focused on the embedded and communications markets.
The toolset includes a range of application packages, advanced triggering to isolate events, a user interface developed for quick and easy navigation, a wide range of probing options, and lightning-fast performance to validate designs, debug errors at board bring up, and characterize an embedded system.
To solve serial data problems connecting probes or cables enables the scope to provide the correct level of detail needed to view, debug, and analyze the serial data signals. A combination of decode, trigger, measure/ graph, ProtoSync, and compliance tools address the embedded, military and avionics, and handset/mobile/cellular markets.
The WavePilot control area provides convenient operation of cursors, decode, WaveScan, history, LabNotebook, and Spectrum by their respective function buttons on the front panel. The SuperKnob is a joystick-like knob in the center of the WavePilot control area used to navigate through tables, zoom and position waveforms, and quickly document and annotate setups.
A combination of high bandwidth edge and 10 different SMART triggers, four stage cascade triggering, measurement trigger, and TriggerScan are all standard, and will isolate the problem quickly to permit focus on the cause. The measurement trigger offers a option to qualify a trigger event based on a qualified measurement with great resolution. A full range of serial triggers (I2C, SPI,UART, RS-232, Audio (I2S, LJ, RJ, TDM, CAN, LIN, FlexRay, MIL-STD-1553, 8b/10b, USB2 and many others) are also available.
History mode enables scrolling back in time to isolate anomalies, measure them with parameters or cursors, and find the source of the problem. History mode is always buffering waveforms, so no user action is required to save traces other than to invoke the viewer.
TriggerScan uses high-speed hardware triggering capability with persistence displays to capture only the signals of interest. It is good for finding infrequent events on fast edge rates.

Although the Le-Croy technique of squashing a scope and a spectrum analyser into one lump, is a good one, it is not exactly new or unknown is it! The ancient superhet radio has been with us for decades! Even I have used that technique as a test engineer, by using the old spectrum analyser o/p plugged into a digital scope input with a RF Rx input filter, followed by a PC which had a special PCB I designed with 16Ch ADC for DSP input to simply act as an ATE bench for radio products, or Automatic Test Equipment. Back in 1990, even that setup was good to work happily and calibrated as high as 25 GHz. It was only a matter of time before SMD took over and got things littler.
Cheers,
