12-bit scopes get eight channels, vendor adds probes, CAN support

June 17, 2014. Teledyne LeCroy today announced the HDO8000 oscilloscope product line with eight analog input channels, 12 bits of vertical resolution utilizing Teledyne LeCroy’s HD4096 technology, and up to 1 GHz of bandwidth. A variety of mixed-signal, serial data, long memory, and probe options and accessories are available with the HDO8000 oscilloscopes.

Teledyne LeCroy also today introduced the HVD High Voltage Differential probe series, delivering high common-mode rejection ratio (CMRR) across a broad frequency range. And finally, the company today introduced the CAN Flexible Data (FD) Rate Trigger and Decode solution, adding to the existing suite of automotive test tools for CAN, LIN, FlexRay, SENT, MOST, and BroadR Reach.

The HDO8000 is suitable for high-power 3-phase power-electronics system analysis. The global market for power electronics is growing quickly, especially in high-power and 3-phase energy conversion applications focused on distributed power generation (including solar PV and wind) and hybrid electric and electric vehicle (HEV and EV) propulsion systems. New and expanded efficiency requirements for electric motors and variable frequency (motor) drives are also driving higher demand for 3-phase power electronics.

Additionally, 8-channel high-definition oscilloscopes are useful in debugging deeply embedded systems in applications such as automotive electronic control units (ECUs), consumer appliances (such as washing machines and refrigerators) and industrial systems (including robotics) that contain a complex mix of power-electronic, power, clock, digital-logic, serial data, and analog sensor signals. More channels and more resolution provide faster insight into embedded system behavior.

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 8-bit oscilloscopes. In addition to HD4096 technology, the HDO8000 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.

Teledyne LeCroy’s new Q-Scape multi-tabbed display provides four times the display area and better organization of large numbers of channel, zoom, and math waveforms (up to 40 total) on the oscilloscope’s 12.1” WXGA high-resolution display. Four tabbed displays are provided. Waveforms can be simply dragged and dropped to the desired location to conveniently organize the many different acquired and calculated waveforms for more intuitive analysis. Q-Scape is especially helpful in three-phase system analysis as each phase can be displayed on a dedicated tab.

For those desiring a larger display area and even higher display resolution, the HDO8000 supports extended-desktop operation with a WQXGA (3,840 x 2,160 pixels) DisplayPort 1.2 video output. Q-Scape tabbed displays may then be viewed on a larger display while another program (for instance, MATLAB) is viewed on the smaller oscilloscope display.

The HDO8000 is standard with 50 Mpoints/channel of acquisition memory with options for 100 or 250 Mpoints/channel. These long acquisition memory options are suitable for power electronics and embedded/mechatronic systems where high-speed microprocessor signals may be captured coincidentally with lower speed pulse-width modulated (PWM), serial data or analog sensor signals. The Teledyne LeCroy deep toolbox is provided for statistical, frequency and time-domain analysis using tracks, trends, histograms, and a variety of other math and measurement capabilities. Tracks are particularly useful for PWM analysis. A variety of other application-based software options are available.

An Intel Core i5-4670s Quad (core) motherboard with 8 GB of RAM provides fast and efficient processing of acquired channels and calculated waveforms, and additional capability when third-party programs are run on the oscilloscope.

Models are available at 350 MHz (HDO8038), 500 MHz (HDO8058), and 1 GHz (HDO8108) of bandwidth. The HDO8038, HDO8058, and HDO8108 are priced at $23,850, $26,850, and $29,850, respectively. A 16-digital-channel MSO option (HDO8k-MSO) is priced at $2,800, and the 100 Mpoint/channel (HDO8k-L) and 250 Mpoint/channel (HDO8k-XL) are priced at $8,000 and $10,225, respectively. A variety of other probe, serial trigger/decoder, and application package solutions are priced starting at $840. Teledyne LeCroy expects to begin customer shipments of HDO8000 models in August 2014.

High-voltage probes

Teledyne LeCroy also today introduced the HVD High Voltage Differential probe series delivering high common-mode rejection ratio (CMRR) across a broad frequency range. The new HVD differential probes are safe, easy to use, and suited for a variety of power electronics measurements. The wide 1,500-V p-p differential voltage range and large offset capability provides flexibility for capturing gate drive and control signals floating on a 1,000-VDC bus. This performance combined with 1% DC and low-frequency gain accuracy means the HVD differential probes enable high-precision, high-voltage measurements.

The HVD probes connect to the oscilloscope through the ProBus interface. The ProBus provides power to the probe so there is no need for a separate power supply or batteries. Attenuation is automatically selected based on oscilloscope gain range (V/div) setting and a probe autozero can be easily performed through the oscilloscope channel menu.

The high CMRR combined with the low noise and high offset capability makes the HVD probes capable of measuring very small control signals floating on high common-mode voltages.

The HVD high-voltage differential probe series has two models: the HVD3102 (25 MHz, 1,500 V p-p, 1000 V rms) and the HVD3106 (120 MHz, 1,500 V p-p, 1,000 V rms). The US list prices are $950 and $1,350 respectively.

CAN FD trigger and decode

And finally, the company today introduced the CAN Flexible Data (FD) Rate Trigger and Decode solution, adding to the existing suite of automotive test tools for CAN, LIN, FlexRay, SENT, MOST, and BroadR Reach. The CAN FD trigger and decode solution enables designers using this new standard to gain insight in to their systems, correlating physical-layer signals and protocol layer data on a single display. The CAN FD trigger can isolate frame IDs, specific data packets, remote frames, and error frames. The decode uses a color-coded overlay that clearly identifies different parts of the data being captured, allowing the user to quickly identify different parts of the CAN FD data such as Frame IDs, status bits, and message data.

Teledyne LeCroy offers the ability to decode four buses simultaneously. These four buses can be a combination of any protocols, including CAN FD and classic CAN, at the same time. Decoded data can also be seen in an interactive table. Entries in this table can be selected and automatically zoomed, preventing the need to scroll through long records. To further simplify how data is located, a search function is built in to the zoom trace to quickly locate a specific Frame ID or data message.

CAN FD is the next generation of the popular CAN standard. As CAN has reached the bandwidth limits of what it can transmit, CAN FD enables higher bit rates and longer data payloads. CAN FD goes beyond the 1-Mb/s limit of classic CAN and will transmit data at up to 10 Mb/s. CAN FD data payloads may now consist of 64 bytes per frame as opposed to the 8 byte per frame limit of classic CAN.

CAN FD Trigger and Decode is available on a variety of Teledyne LeCroy oscilloscopes and has a list price of $2,990. Teledyne LeCroy oscilloscope users who already have CAN Trigger and Decode can upgrade their system to CAN FD Trigger and Decode.
