Transfer function measurement

Open-loop chirp measurement

Support various digital interfaces with jitter function for reference, synchronization, and triggering of advanced master clock signals

Independent output channel configuration

Multi mode user interface

The APx500 measurement software enables the B-series APx555 to meet the various needs and preferences of audio designers, engineers, and technicians.

Sequence Mode provides a complete and code free automated predefined measurement sequence to quickly obtain reliable test results.

The Bench Mode provides a real-time window that displays waveforms, FFT, and other key parameters.

ADC Test Mode Options

The ADC test mode option provides adjustable common mode VBias DC bias voltage on balanced analog output. After enabling the pin voltage protection mode, it can prevent overvoltage damage to the input terminal of the ADC device during performance testing.

flexibility

APx555 supports all APx digital I0 options, ensuring compatibility with multiple audio formats and devices.

Digital Serial--12S，TDM， Multi line support (including jitter *)

Bluetooth@-- Support A2DPAVRCP, HFP, and HSP configuration files

HDMI+ARC - Signal source, receiver, and monitor (including metadata)

PDM - Single byte audio generation and analysis (including PSRR and jitter *)

Advanced Digital - AES/SPDIF/Optical (including jitter *)

*The advanced master clock is standard on APx555 and supports all digital interface modules with jitter function.

APx555B series software options

In addition to supporting the core functions of the APx555xB series analyzer, the APx500 testing software also provides some special testing options, with multiple choices to meet the testing needs of electroacoustic and perceptual audio.

Simultaneously provide software maintenance options to extend the standard warranty period of the new APx analyzer. You can also upgrade the old APx analyzer to the current software version and add software maintenance options. The software maintenance option allows users to upgrade to the next generation software version and extend its use for many years.
