Case Study: Leading Latest Wireless Component Manufacturer achieves 41% risk reduction and ~51% annual cost savings by reducing measurement uncertainty with Keysight calibration and risk calculator

Component Manufacturer Uses Calibration to Detect Changes in Test System Measurement Uncertainty

Leading Latest Wireless Component Manufacturer, an industry-leading maker of filters and front-end components for modern wireless devices, faced growing measurement uncertainty in S-parameter tests (notably ripple deviation) caused by instrument, cable, and connector drift. These uncertainties threatened pass/fail accuracy, squeezed design margins, and risked missing ramp-to-volume targets. The customer engaged Keysight, using Keysight’s calibration services and Electronic Calibration Module along with Keysight’s risk calculator to address the problem.

Keysight analyzed correction terms to detect a faulty connector, performed calibration that restored measurement uncertainty from ±0.5 dB to ±0.2 dB, and used its risk calculator to quantify business impact: false passes fell from 1.56% to 0.92% (a 41% reduction), false fails dropped from 6.86% to 1.75% (74% decrease), and estimated annual cost savings were about 51%. Armed with these measurable results, the manufacturer justified investing in Keysight calibration services to lower risk and cost.
