The Signal Analysis Meter is a full-featured handheld signal performance meter providing a complete signal test system in easy-to-carry protective case. Signal Analysis Meter allows choice of 4 pre-programmed user-selectable band plans accessed via keypad entry for easy measurement of broadcast, CATV, CATV/HRC, and SUB/VHF channels. Direct-entry channel or frequency tuning selections provide maximum flexibility in head-ends and distribution networks that employ narrow digital signals or non-standard frequency applications. The meter displays instantaneous digital signal levels when testing digital carrier levels. The large LCD screen displays signal level as a bar-graph with digital numeric readout. This backlit display provides screen illumination in dimly lit work-spaces, allowing behind rack and night meter operation. Signal Analysis Meter enables testing of carrier-to-noise, multiple channels, and full, reduced, and single band scan for complete testing flexibility. The meterí»s functions include not only signal measurement when AC/DC voltage is present under test, but, when selected, voltage-level display. Full-channel operation 5-870MHZ Frequency Range 4-keypad channel plans (TV, CATV/STD,CATV/HRC,SUB/VHF) enable quick switching between sources Single keypad frequency or channel selection provides compatibility with channel, data, and other narrow bandwidth carriers Full spectrum-analyzer scan provides display of up to 100 channels simultaneously Carrier-to-noise testing provides accurate testing of system performance anywhere in the head-end or distribution system Large easy-to-read backlit Graphic LCD display provides quick-glance signal reference even in dimly lit work environments AC/DC voltage readings and compatibility allow measurements through input connector, enabling signal and voltage measurements when voltage is present in tested signal without costly adapters 8-Hour rechargeable NiMH batteries provide cost savings Automatic power shut-off feature extends time between recharges Bright orange high impact plastic housing and soft leatherette-vinyl protective case with belt clip included 8 pieces in one carton
