* Products for Upstream Cable Plant Testing

Burst Viewer monitors upstream noise and traffic using a time-domain capture of impulsive events, such as noise bursts, data packets, and test signals.

Cable Scope® measures the complex frequency response of a return signal path to yield both the magnitude of the frequency response as well as the group delay.

Cable Clothespin® is a device that tests for the presence of shield breaks in coaxial cable plant by inducing a sheath current on the outside of the shield and measuring a returned signal on the center conductor. Shield breaks cause severe disruptions of upstream services by allowing ingress and burst noise to corrupt upstream signals.
