Parallel four bluetooth headphone audio test
In the recent development of Bluetooth testing, the parallel "dual" Bluetooth test is required almost by each client. The dual Bluetooth test is preferred for its higher equipment and staff utilization and efficiency. The quadruple Bluetooth test system is an extreme upgrade to dual Bluetooth, with minimal hardware changes in exchange for maximum efficiency breakthroughs. From dual Bluetooth to "Quadruple Bluetooth", the test efficiency is doubled, and the UPH of a single device is up to 400. Test products cover Bluetooth PCBA, semi-finished and finished Bluetooth products.
