ZC5920 multi-channel bluetooth headphone life tester

Brief Introduction


With the mass shipment of bluetooth headsets and speakers in the current consumer market, there are new requirements for the aging detection equipment of bluetooth series. The company to comply with market demand, timely research and development of multi - channel bluetooth life tester. Due to the high frequency characteristics of bluetooth, which is greatly affected by environmental shielding, our r&d personnel focus on solving the shielding problem and develop a stable bluetooth transmission solution. At the same time, high performance silicon wheat is adopted to collect the sound emitted by earphones in real time and quantify the size of playing signal of earphones. ZC5920 is a test device to test the status of bluetooth connectivity and monitor whether the headset has continuous output.

Performance Feature

  • Drive signal source: built-in sine wave, sound card plays audio signal.

  • Test channel: 20 pairs of earphones or 20 bluetooth speakers can be connected at the same time.

  • 8 "LCD panel: channel, aging time, headset output voltage, bluetooth connection status.

  • System: industrial computer Windows system, easy to operate.

  • LAN network interface: test data can be uploaded to the company server for convenient data analysis.

  • Trial range: bluetooth headset, bluetooth speaker, TWS headset.
