Description
RTW SW20002 Overview
The RTW SW20002 Loudness and SPL Display Module software works with the TM7,TM9 and TMR7 TouchMonitor models. It expands the basic stereo PPM with Loudness measuring functions as described in current guidelines (EBU R128, ITU-R BS.1770-3/1771-1, ATSC A/85, ARIB, OP-59), 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 two channels software module SW20001 is required.
