The LF 983 measures analog signal levels for VHF/UHF/FM/CATV; as well as digital (8VSB, OFDM, QAM 16-256) and satellite analog and digital (QPSK, 8PSK, BPSK, MSK) modes. Sub-band frequency coverage from 5 to 55 MHz is standard. Storage of 200 sets of data and 200 setups facilitates data collection and clonin. Data logger stores readings direct to a standard flash memory card and then easily transferred to a PC. Resume, on power-up, returns to the last screen viewed.
Audio monitoring is via a built-in speaker and line output. A video-out jack sends, in the clear, composite video to a color picture monitor. Analog and digital reception is verified with a basic spectrum display. For satellite C/N and LNB drive is provided. Programmable power-off extends operating time. The meter is supplied with a charger/adapter, battery pack, spare battery tray and a carrying case.
