The Spirent TAS5100C is a precision channel and clock emulator engineered for laboratory validation of wireless devices and synchronization systems. This instrument simulates complex propagation environments and timing conditions, enabling rigorous testing of LTE, Synchronous Ethernet, and legacy telecom infrastructure under controlled, repeatable scenarios. The TAS5100C measures time interval error (TIE) and absolute time error (ATE), displaying results against industry-standard masks in real time.
