Press Release Trilithic’s Media Contact: Karalee Slayton Director Marketing & Communications 317 423-6604 kslayton@trilithic.com New Product Release: SpeedSweep System Indianapolis, Indiana (Wednesday June 21, 2006), Trilithic is pleased to announce the introduction of the new SpeedSweep System™, which combines the traditional method of inserting sweep signal at unoccupied frequencies, and referencing existing service signals with DSP (digital signal processing) technology to enable a significantly faster sweep sample on digital channels. The system, used for HFC plant maintenance, expands the breadth of measurement modes on the 860 DSPi field analyzer through the new FR-1 option that enables forward and reverse sweep and alignment. Fielded 860’s with the SR-1 or VP-1 options can be updated via a simple firmware upgrade – no return to the factory required. The downstream sweep (5MHz to 1 GHz) is generated by the new 8300 FST Forward Sweep Transmitter. The return sweep is received by the new 9581 RSA Return Sweep Analyzer, and the measurement information is displayed on the 860 DSPi at the field test point. The 9581 RSA handles the reverse sweep in addition to supporting Trilithic legacy return test/alignment equipment, enabling technical operations to offload this function from 9581 SST’s currently used for return path monitoring, thereby even further increasing the unmatched ability to capture transient ingress and impulse noise with high speed DSP analysis – 120 spectrum snapshots per second per node.
