Leader LF52 Signal Level Meter

The Leader LF52 Signal Level Meter is a multi-function field-measurement device designed specifically for the ISDB-T terrestrial digital television format that's being implemented in the Philippines and South and Central America and is already in place in Japan. The reliable, accurate portable device contains a surprising number of robust analysis functions for a unit of its size and cost.

Supporting both analog and digital terrestrial broadcast systems, the meter is ideal for analyzing systems that are undergoing a transition from analog to digital. The LF52 also supports satellite and CATV RF signals. The device accepts 5 MHz - 870 MHz frequencies for digital terrestrial and 950 MHz - 2.6 GHz for satellite signals frequencies. Compatible with OFDM, COFDM, BPSK, QAM and other modulation formats, the LF52 measures RF level, carrier to noise level (C/N), BER, MER, and delay profile.

The LF52 device's STN monochrome LCD displays measurements as a simple spectral display or as a constellation pattern. Up to 200 presets can be stored and recalled. A measurement log is provided, and measurements can be output as comma-separated values for use in a spreadsheet. RS-232 control is possible, for data output, remote control, and for connection to a printer.
