Enhanced capabilities for AES, SPDIF and TOSLINK

The APx ADIO (Advanced Digital I/O) module provides AES3, AES/EBU balanced digital I/O on XLR; unbalanced SPDIF digital I/O on BNC; and TOSLINK optical digital I/O. “Advanced” in the ADIO module’s nomenclature reflects its ability to generate impairments for sophisticated test of devices via AES/SPDIF/TOSLINK, a feature that is unavailable in the DIO module (Digital I/O; standard on APx52x Series and APx58x Series analyzers). ADIO also includes the Advanced Master Clock (AMC) module.

Advanced Master Clock

The AMC module handles input and output clock signals to synchronize APx500 Series analyzers with external equipment (or vice versa). This module also enables jitter generation and analysis in APx500 Series analyzers with Advanced Digital (ADIO), Digital Serial (DSIO) or PDM modules installed. The AMC module is standard on APx555 analyzers, and is included with the ADIO module option for APx52x Series and APx58x Series modules.
