TRILITHIC introduces the only preselector that offers filters for testing both on the return path and forward path. Return path preselection is provided by six precision fixed filters tuned to channels T-7 through T-12 respectively. Preselection in the 55–880 MHz range is provided by four tunable filters. Each filter, whether tunable or fixed, provides a high-selectivity shape factor of 2.2:1 for 30 dB to 3 dB, sufficient for the most demanding CATV test applications. All filters are housed in a single rugged, portable field case which can also contain the optional AM-1000, a 50-1000 MHz, 20 dB pre-amplifier powered by a rechargeable NiCad battery pack.
