The New BTC-4148 enables Bluetooth devices to be accurately tested in SoundCheck® by offering full control over the Bluetooth connection.
Accurately measuring Bluetooth devices is challenging. The Bluetooth protocol is a dynamic and adaptive system that provides devices with many options and parameters that are normally negotiated and set in an invisible manner. Using typical PC Bluetooth interface devices as an audio bridge in test applications is not ideal as the compression codec, sample rate etc. cannot be controlled and the engineer is left guessing as to what values are actually used.
The BTC4148 overcomes this by offering full control over all Bluetooth protocol settings and explicit control over all the CODEC, sample rate transmitter power etc. This enables devices to be specifically tested under the conditions that they need to operate.
