The RPM1000 module is an eight port, high-speed return path spectrum analyzer optimized for the noise and ingress analysis and monitoring functions of the PathTrak Performance Monitoring System. Each of the eight ports is an independent and isolated test port. The RPM1000 module switches automatically between the eight ports and measures spectrum performance on each individually. The measurement settings and functions of the RPM1000 consist of all typical spectrum analyzer settings such as resolution bandwidth, video bandwidth, dwell time, span, marker control, max hold, min hold, peak search, etc. The RPM1000 provides flexibility to adjust these parameters in monitoring plans, or interactive analysis according to individual preferences.
