The RP100 is a Multicarrier Signal Generator designed for the activation and later verification of the return path in CATV systems. The unit generates up to four independent carriers where frequency and output levels can be set by the user. Combined with a cable TV analyzer, for example the PROMAX-8+, it becomes a highly useful tool to carry out the TILT measurements in the return path. The RP-100 incorporates an auxiliary RF input to allow for signals to be continued with other RF signals.
