Memory architecture provides capabilities for high performance content search. The system includes a plurality of collector devices that are disposed to collect data and statistical information on packets that are sent between nodes on a network. The printer is capable of detecting when the level of the print material is at a different one of a plurality of pre-determined levels. Rebalancing is performed until the difference in free disk spaces falls below the threshold without exceeding the maximum execution time of rebalancing. In specific embodiments, the modulation can be amplitude modulation where the modulating signal is lower in frequency than the RF signal and is related thereto by a rational number, such as one-half.
