The Signalysis Power Seat Test System replaces subjective tests with advanced vibration, sound, motor current and travel velocity algorithms and metrics. Based on more than 30 years of experience, the proven power seat test system combines traditional NVH laboratory modal analysis, sound quality, gear testing, and motor dynamics test methods bringing 100% inspection confidence to your manufacturing floor.

IQC MATERIAL HANDLING controls the part in place and provides the required vibration isolation from the manufacturing facility.

IQC MOTOR CONTROL powers the seat and controls the motions to maximize cycle time while optimizing test data integrity.

IQC MEASUREMENT SYSTEM acquires dynamic response data from a defined set of transducers, sampling rates, digital filters, and sample sizes.

IQC ANALYSIS ENGINE employs high-level post-processing in time and frequency domains to detect faults in drive motors, gear systems, and other mechanical or moving parts during seat travel.
