EMC: COMPLIANCE TESTING Accessible pre-compliance


RFI and instrumentation specialist Tektronix is providing pre-compliance EMC testing systems as an affordable alternative to complex lab equipment or repeated test house visits


environment, about 50 per cent of products fail electromagnetic compatibility (EMC) testing the first time, according to an Intertek white paper. To reduce such a high chance of failure, EMCVu gives engineers an accurate, convenient and cost-effective approach to determine if their product designs will pass EMC emission compliance testing first try.

HIGHER FOCUS ON EMC With the arrival of the Internet of Things (IoT) and a proliferation of electronic devices that can interfere with each other, designing products to meet EMC emission requirements is more critical than ever, due to the more complex RFI environment. For many engineers just starting work on new IoT devices, EMI/EMC testing can be intimidating, and failing compliance testing leads to significant cost overruns and schedule delays. Pre-compliance testing reduces failure rates but introduces its own challenges, including difficult & expensive equipment set up, testing accuracy, tedious debugging, and a lack of reporting tools. “Meeting EMC compliance starts with good design, board layout and component

selection. But even in the best of circumstances getting through compliance testing can be a gamble without pre- compliance testing,” said Kenneth Wyatt, principal consultant of Wyatt Technical Services and EMC compliance expert. “I applaud what Tektronix is doing with EMCVu to make pre-compliance testing more accessible to more engineers, even those who lack deep EMC expertise.” According to Jon Baldwin, vice president


and general manager, Wideband Solutions Business Unit at Tektronix: “EMC compliance testing can challenge even the best design team. You pass EMC testing, or you don’t ship your product. It’s that simple. “At Tek, we are focused on how to help


our customers accelerate their time to market. We have delivered a product that transforms EMC compliance testing from a potential roadblock to a check box any engineer can tick.”


TEKTRONIX EMI/EMC PRE-COMPLIANCE TEST SYSTEM At the core of the new system are the Tektronix real-time USB spectrum analysers, including the affordable RSA306B, that offer the performance of


traditional desktop instruments at a fraction of the cost. Powered through the USB connection, the small size of the Tektronix real time USB spectrum analysers makes it easy to perform EMI/EMC testing outside the lab in relatively low-noise environments. The instruments are controlled by


SignalVu-PC software running on a laptop or tablet. SignalVu-PC has been enhanced for pre-compliance and troubleshooting in the same user interface with optional EMCVu software. EMCVu includes an easy to learn wizard with built in support for standards, such as CISPR (International Special Committee on Radio Interference), and push-button accessory selection and set-up. It also makes debugging easy with automated ambient noise capture, multi- failure remeasurement and harmonic markers for detailed analysis. Users can easily save experiment results with notes and images into a configurable report in PDF or RTF formats. The spectrum analyser and software are


complemented with a comprehensive set of accessories that have all been carefully selected and thoroughly evaluated to maximise test efficiency. To ensure accurate results and save time for users, the loss or gain of the various accessories has already been captured in the software and is accounted for during measurements. EE
