Adaptor shows multiple channels on oscilloscope display

Pickering Interfaces and Agilent Technologies are introducing a wired trigger bus (WTB) adaptor that allows Agilent 6000 and 8000 series mixed-signal oscilloscopes (MSOs) to show the logical state and analogue representations of all eight LXI WTB channels on a single display. This is claimed to be the only adaptor on the market that is able to do this.

The LXI WTB adaptor provides a simple and elegant method of exchanging trigger signals between LXI devices that use the WTB. It replaces ad hoc trigger systems commonly seen in GPIB-based automated test systems where instruments can exchange proprietary triggers between devices using coaxial cables and other digital I/O connections. The LXI WTB provides a way of exchanging these trigger signals with a standardized interface that eliminates the makeshift wiring, signal routing, switching and level buffering over distances exceeding 10m with low latency and high speed.

Scott Sampl, vice president and general manager of Agilent's System Products Division, comments: "This is a great example of how companies are collaborating to provide the best experience for users of the new LXI standard. This adaptor is one more tool that will help engineers develop test systems quickly."

David Owen, business development manager for Pickering Interfaces, adds: "Our 60-981 and 60-990 adaptors are valuable debugging tools for LXI test systems that support the WTB system. They make it easy for integrators and users to see what is happening on all the WTB channels simultaneously using a simple interface that exploits the powerful digital features of the Agilent 6000 and 8000 series MSOs."

Pickering Interfaces' new 60-990 adaptor connects directly to an Agilent MSO 40-pin connector via an Agilent lead and to the LXI WTB via standard WTB cable assemblies. The Agilent MSO provides the power for the 60-990 adaptor.

Using the digital channel input for the MSO oscilloscope, the logical state of all eight LXI WTB channels can be simultaneously displayed. Using a Pickering Interfaces 60-981 WTB probe, the analogue waveforms of a LXI WTB channel can be simultaneously displayed.

Agilent 6000 and 8000 series MSOs measure a combination of signal types and speeds with two or four analogue channels and 16 logic channels that are tightly integrated.
