Case Study: Leading Hearing Aid Manufacturer achieves 25% faster testing and 50% lower manufacturing test costs with Keysight X8711A IoT Device Functional Test Solution

A Leading Hearing Aid Manufacturer Reduced Test Time and Costs with IoT Device Functional Test Solution

Leading Hearing Aid Manufacturing Company, a leading global manufacturer of hearing aids, faced inefficient and risky production testing after adding Bluetooth Low Energy (BLE) connectivity. Their original process required loading special test firmware and using wired interfaces that changed RF behavior, increased product handling, and meant devices weren’t tested with the final shippable firmware. They engaged Keysight to find a safer, faster, and more accurate manufacturing test approach.

Keysight implemented a customized over‑the‑air signaling test path—first a TAP-based proof of concept and then the X8711A IoT Device Functional Test Solution for full manufacturing use—that tests devices in normal operation with final firmware and provides quantitative RF measurements. The Keysight solution cut test time by over 25% per device, reduced manufacturing test costs by 50% per system, eliminated firmware load/unload handling risks, and improved detection of performance-based defects.
