Audio Precision APx Bluetooth option test

The Audio Precision APx Bluetooth option is claimed to be the best solution for testing Bluetooth audio.

The built-in Bluetooth radio and Bluetooth stack allow engineers to measure their devices directly.

With APx, all Bluetooth controls are integrated into the analyser software. In addition to standard commands like pairing or opening a connection, it is easy to switch between profiles and roles on the fly, specify a custom device class, connect with a preferred sample rate or codec, or force open an SCO without ringing.

For deeper protocol analysis, a link key is available to cut and paste into a packet sniffer.

Once connected, every audio characteristic can be measured. Key features include 30+ one-click audio measurements (including all standard weighting filters), one-million-point FFTs, real-time oscilloscope monitoring, custom reports, statistical calculations and quasi-anechoic acoustic measurements.

With 21 measurements in 1 s, the analyser is suitable for Bluetooth production test.
