APx516B Series Audio Analyzer

The APx516B is a two-channel audio analyzer built for versatility. It is compatible with any current or future APx500 digital audio interface module, including Bluetooth, PDM, Digital Serial, and HDMI.

Bluetooth 5
Audio Precision’s Bluetooth 5 module provides an interface to audio devices using the latest version of the Bluetooth specification, including LE Audio devices utilizing Unicast and Auracast. This allows designers and manufacturers of earbuds, headphones, headsets, hearing aids, speakers, automotive infotainment systems or car kits, and other audio devices that interface via Bluetooth to measure the audio characteristics of their device.

Bluetooth Classic 
AP’s Bluetooth module, the APx Bluetooth Duo™, delivers a wider selection of A2DP codecs, faster pair and connection times, an increased feature set within APx500 measurement software, and improved RF shielding for use in production test environments. APx Duo supports Bluetooth core specification v4.2, HFP v1.7, HSP v1.2, AVRCP v1.4 and A2DP v1.3.

PDM 16
The B Series APx PDM 16 option provides 16 acquisition channels for audio devices that have a PDM output (such as MEMS microphones). All 16 channels can be measured simultaneously. Cables are available in 2, 5, and 10 meters.

PDM
The B Series APx PDM option provides direct I/O, modulation, and decimation for powerful test and analysis of PDM devices.

Programmable Serial I/O
The Programmable Serial I/O (PSIO) module is for testing digital audio interfaces and provides low logic voltages, improved signal integrity, and a re-engineered serial interface for high-speed, low-power digital audio devices. This option provides a direct multichannel connection to chip-level interfaces such as I2S, TDM, and other popular serial interface formats including left-justified, right-justified, and DSP. Jitter capable.

HDMI
The B Series APx HDMI option (HDMI2+eARC) allows measurment of HDMI audio quality and audio format compatibility on devices such as surround sound receivers, set-top boxes, HDTVs, smartphones and tablets, and DVD or Blu-ray Disc™ players.

AES/SPDIF
The B Series APx DIO option provides AES3, AES/EBU balanced digital I/O on XLR; unbalanced SPDIF digital I/O on BNC; and TOSLINK optical digital I/O.

Every new analyzer comes with a perpetual license for the current and next major software release, including a limited number of out-of-the-box measurements.
