Tools ease adoption of LXI WTB in test systems

Pickering Interfaces Ltd has released a range of accessories designed to simplify the testing and use of LXI Wired Trigger Bus (WTB) required for Class A LXI Devices. LXI WTB provides a simple and convenient way for LXI Devices to exchange hardware-based trigger signals over a common physical interface that connects all the devices supporting the facility.

The 60-982 LXI WTB Adaptors allow the easy conversion of LVTTL signals to the WTB and the conversion WTB signals to LVTTL, the company said. It provides a simple way of monitoring the logic levels present on the WTB and allows the easy integration of products without built-in WTB capability into a system with WTB support.

The 60-981 WTB Probe allows users to monitor the analog signals present on the WTB, providing wide bandwidth buffered signals that can be used by a high speed scope. With a probe BW of 1GHz, the signals provide an accurate representation of the WTB activity without significantly loading the WTB, explained Pickering.

The 60-983 is an LXI compliant cable terminator that can be used at the end of the WTB to correctly terminate the transmission line. Meanwhile, the 60-985 WTB cable Assemblies are LXI WTB compliant cables available in standard and custom lengths of 0.3m and greater.

"The availability of these accessories is a major step forward in the adoption of the LXI WTB into test systems," said David Owen, business development manager for Pickering Interfaces. "With all the key parts now commercially available, it will become easier to introduce more Class A products and it becomes simple for users to integrate legacy products having different trigger mechanisms into the LXI Trigger model. The presence of just one Class A device in a system will allow users to take advantage of 1588 timing information."
