2: APx555 AES3 / SPDIF capabilities provided via Advanced Digital I/O (ADIO) module, which includes Advanced Master Clock (AMC) for jitter generation and analysis. AES3 / SPDIF capabilities for APx52x and APx58x Series analyzers provided via standard Digital I/O (DIO) module. ADIO and AMC modules are optional for APx52x and APx58x Series analyzers.
