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.
Parallel four Bluetooth test
- One CRY6151B electroacoustic tester and four channels for TWS single-head parallel testing
- Quadruple Bluetooth is the highest-efficient Bluetooth audio test equipment in this industry. The UPH of a single device is up to 400. One such device performs better than two dual Bluetooth ones.
- One piece of equipment can be compatible with single-head quadruple testing and double-head dual testing. Our specific software enables one-touch switching without any software change.
