Model BTC-4148 and BQC-4148 - Bluetooth Measurement Interfaces
Listen offers 2 Bluetooth interfaces from Portland Tool & Die, the laboratory-grade BTC-4148 and the low cost BQC-4148 for production line use. These are ideal for measuring and characterizing Bluetooth audio devices including handsets, headsets, speakers, car kits and other devices with Bluetooth audio input or output. The BTC-4148 and BQC-4148 interface your Bluetooth device to the SoundCheck test system offering full control over all Bluetooth protocol settings and explicit control over the CODEC choice, and transmitter power. This enables devices to be specifically tested under the conditions that they need to operate, and enables comparison of characteristics such as frequency response using different compression algorithms or sample rates.
The BTC-4148 measures both Bluetooth sink devices ...
The BTC-4148 measures both Bluetooth sink devices (e.g. headsets, speakers and car kits) and Bluetooth source devices (e.g. phones and dongles), offering a comprehensive range of features for R&D users. These include:
- Bluetooth 3.0 compliant RF interface
- Comprehensive suite of codecs, protocols and other parameters including:
- A2DP: SBC and APT-X codecs
- Hands Free Protocol (HFP) and Headset Protocol (HSP): CVSD and mSBC codecs
- Full control over bluetooth protocol settings, codec choice and transmitter power
- Control via touch-screen panel on the front of the instrument, or directly via SoundCheck
- Pairing via inquiry/discovery or directly by device address
- The host interfaces via USB for both audio and control data and a parallel SPDIF interface for audio data. Audio is always transported in the digital domain to maximize measurement fidelity
