Case Study: Electronic Technology Company achieves cost-effective, 120‑channel synchronized audio extraction for vehicle NVH testing with Advantech

A Cost-Effective Audio Extraction Solution for Vehicle NVH Testing

Electronic Technology Company, a Shanghai‑based developer of sound, vibration and acoustic measurement and analysis systems, needed to update its automobile NVH testing platform to meet rising demand while lowering hardware costs. The company sought a cost‑effective audio extraction solution from Advantech that could support large IEPE microphone arrays, numerous PCIe slots, multi‑channel 24‑bit sampling at ≥100 kS/s, IEPE biasing and a wide input range, plus true simultaneous sampling across multiple acquisition cards.

Advantech supplied an audio extraction system built on the IPC-623 4U 20‑slot chassis with PCE-5B19 backplane, up to fifteen PCIE-1802 8‑channel, 24‑bit/216 kS/s PCIe acquisition cards, and the PCL-10419 high‑speed multi‑card sync cable (with PCL-108BNC cabling). The solution supports up to 120 IEPE microphones (more than 100 channels sampling simultaneously), synchronizes cards to nanosecond accuracy, preserves high resolution and IEPE flexibility, and delivered a cost‑effective platform that improved Electronic Technology Company’s NVH testing capability and market competitiveness.
