RTW SW20002 Loudness and SPL Display Software Module for TouchMonitor Series

This module expands the basic 4-channel PPM with Loudness measuring functions as described in current guidelines (EBU R128, ITU-R BS.1770-4/1771-1, ATSC A/85, ARIB, OP-59, AGCOM, CALM, LEQ(M), TASA, SAWA), and the LRA instrument for the graphical display of the Loudness Range. A customer-specific mode allows the user to modify parameters. In addition the module provides the SPL display mode with various weighting filters and integration times as well as reference level adjust to calculate an SPL value from an electrical signal.

For signals with more than four channels software module SW20001 is also required.
