DSLA

Overview

The Opale Digital Speech Level Analyser (DSLA) is a specialized hardware instrument designed for precise measurement and analysis of speech signal levels and quality across telecommunications and audio systems. It serves as the hardware agent for the powerful MultiDSLA platform, enabling comprehensive connectivity and analysis for devices and networks under test. Together, they provide a scalable, objective, and standards-compliant solution for device manufacturers, network operators, and service providers.

MultiDSLA Platform

Acts as the central control and analysis software environment.

Provides test configuration, execution, results collection, and advanced reporting.

Supports remote management and automation for distributed test environments.

DSLA Hardware Agents
