Teledyne LeCroy Upgrades Voyager M310C USB 3.1 Protocol Analyzer with Power Delivery Exerciser

Teledyne LeCroy, a worldwide leader in serial data test solutions today released a major upgrade to their Voyager M310C SuperSpeed USB 3.1 protocol verification platform. A comprehensive Power Delivery (PD) exerciser capability is now available for developers to verify functionality, error recovery, and compliance for PD chipsets and end-products. Targeting the growing adoption of the new USB Type-C connector, this software release also adds several enhancements for Power Delivery debug including PD triggering, event stacking, transaction grouping and Verification Script Engine (VSE).

Integrated in Teledyne LeCroy's flagship Voyager M310C USB 3.1 test platform, the Power Delivery exerciser supports traffic generation, including both provider and consumer device emulation. The script-based authoring environment provides pre-defined templates for all Power Delivery packet types. Overrides can be added inline to allow low-level control of headers, payloads, timing, or logical protocol errors within the PD communication channel. Advanced functions including If/Else, Wait, and Do Case allow emulating complex PD behaviors including contract negotiation and power role swaps.

"The new USB Type-C connector is gaining rapid support with top-tier PC and electronics manufacturers. Testing and verifying this new functionality will be essential for developers targeting PD and Type-C applications." said Michael Romm, General Manager at Teledyne LeCroy's Protocol Solutions Group. "The industry-leading Voyager M310C with the new PD exerciser option now represents the ultimate test platform for validating interoperability for the next 10 years of USB development".

The exerciser mode features PD Transaction Manager™ which automatically handles transaction layer handshaking to speed test script development. This mode will track MessageID fields and perform the GoodCRC handshakes allowing Power Delivery transactions to occur dynamically. Flexible control for resistor voltages (Rp / Rd / Ra), as well as programmable VCONN and vBUS settings allow precise testing of cable detection and orientation logic. The exerciser can operate as a full 100 Watt source and 5.00 Amp sink (with external load).

The Voyager M310C exerciser uses standard USB Type-C cables directly connected to the system-under-test (SUT) to generate Power Delivery 2.0 as well as USB 3.1 SuperSpeed Plus traffic. Generating and capturing both USB and PD traffic over the same cable allows testing the entire enumeration sequence including the Power Delivery class specific descriptors.

"The PD Exerciser mode leverages an open scripting architecture and our robust automation framework to create a flexible, end-to-end test capability for USB Type C and Power Delivery" added Mike Micheletti, Product Marketing Manager at Teledyne LeCroy's Protocol Solutions Group. "Finally, USB Developers have a no-compromise solution which combines our best-of-breed support for 10 Gb/s SuperSpeed Plus with Power Delivery allowing comprehensive testing of USB functionality and compliance."

USB Protocol Suite Version 7.20 is now shipping with the Voyager M310C system which enables the Power Delivery mode for exerciser customers. Voyager M310 users that have previously purchased the USB 3.1 exerciser option can access the PD exerciser by updating to USB Protocol Suite Version 7.20.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
