You have taken an excellent step toward alleviating the problems of your return path with your purchase of this 9580 Return Path Maintenance System. Trilithics 9580 is designed to monitor all of the troublesome parameters in a single, simple to use system. The 9580 is part of Trilithics Guardian Return Alignment System which includes the 9580 SST, 9580 SSR, RSVP Installer Return Test Units and Isometer. It is more than just a return alignment system, however. The system also monitors the total performance of the return path by evaluating ingress and return noise. With the 9580s FAST Mode, you can increase the effective scanning rate of the INGRESS Modes spectrum analyzer. This enables you to catch the transient events. PEAK HOLD enables the Unit to display the highest ingress points in NORM or FAST Modes. This makes the SST a powerful tool for capturing transient ingress. The AVERAGING feature is an option you can get for the SST. It is used in FAST and ZOOM Modes to reduce the noise floor displayed on the SST when measuring CW or common path.
