Sound Calibrator HS6020

The HS6020 sound calibrator is mainly used for testing the sound pressure sensitivity calibration of microphones and acoustic measuring instruments. It has the characteristics of small size, light weight, stable performance, and easy use, and meets the technical requirements of Class I calibrators in IEC942 "Sound Calibrators".

A2B Audio Interface

A2B-ADIO is an analytical solution developed based on the emerging A2B technology for automotive audio buses, specifically designed to meet the measurement needs of manufacturers in the automotive and consumer electronics audio industries. This audio interface has flexible A2B network configuration and rich audio input and output interfaces. Combined with audio testing software, it can efficiently perform audio testing of various A2B components, such as car infotainment systems, car amplifiers, car microphones, etc., making it very suitable for research and production testing.

PDM Extension Adapter AB-PLD

The PDM extension cable adapter addresses the distance issue between PDM microphones and audio analyzers during testing. It provides buffering for PDM audio data, allowing the use of cables up to 45 feet (13.7 meters) in length between the DUT and analyzer without loss or alteration of the digital signal.

Impedance Box

Speaker impedance testing accessory, paired with an audio analyzer, can be used for speaker impedance testing.

Bluetooth Adapter

Specially designed for Bluetooth products and their automated testing, in addition to providing Bluetooth connection with the tested product, it also offers 2 analog audio input/output interfaces. With the help of an audio analyzer, it can perform Bluetooth audio (A2DP and HFP) indicator testing for the tested product, and support function testing such as up and down songs, addition and subtraction volume, battery level, pause and answer.

Filter 20K

Dual channel multipole LRC passive low-pass filter, mainly used for audio measurement of Class D amplifiers. It can provide out of band attenuation for audio and reduce the steepness of fast transition edges, providing signal preprocessing for testing accuracy, with a passband of 20-20kHz.

Filter 40K

Filter 20K

8-channel passive low-pass filter, mainly used for audio measurement of Class-D amplifier. It can provide audio out of band attenuation and reduce the steepness of fast conversion edges, providing signal preprocessing for testing accuracy. It has a passband of 20-20kHz and is designed specifically for use with the A8 series audio analyzers.

Audio Switch

Audio switch box, used to expand the input/output capability of dual-channel audio analyzers. It can extend 2 input/output channels to any two of the 12 input/output channels, avoiding the need for cable plugging and unplugging due to interface changes during multi-channel product testing, thereby improving testing efficiency.
