Keysight Technologies, Inc. introduced theenhanced U8903B audio analyzer with newBluetoothaudio measurement capabilities. TheBluetoothoption enables the U8903B to make high-performanceBluetoothaudio testing for R&D, quality assurance and production tests in the consumer and professional audio and wireless communication industries.
The U8903B operates withBluetoothversion 4.0 and supports AGHSP/HSP 1.2, AGHFP/HFP 1.6, A2DP and AVRCP profiles. The U8903B transmits a maximum output power of 5 dBm, ensuring that engineers can connect to, and accurately test, a wide variety ofBluetoothdevices such as headsets, smart devices and automotive head units.
“The U8903B’sBluetoothoption provides capabilities that allow users to make convenient and high-performanceBluetoothaudio measurements,” said Ee Huei Sin, vice president, Keysight’s General-Purpose Electronic Measurement Division. “With this new option, Keysight now offers a powerful one-box solution that enables engineers to test analog, digital andBluetoothaudio applications.”
To easily monitor the quality of theBluetoothlink and troubleshoot connection issues, the U8903B comes with the received power indicator and bit error rate measurement. The received power indicator is a visual indication of the power strength of the device-under-test (DUT), and gives users a quick and convenient way to check that theBluetooth-RF link is strong enough. The bit error rate measurement shows the amount of error, given as a percentage, in the connection between the U8903B and theBluetoothDUT. By monitoring changes in the bit error rate value, engineers can determine the causes of the link quality deterioration.
The U8903B audio analyzer also offers local loopback capability to provide fast and accurate loopback testing ofBluetoothchipsets, modules and devices. This feature allows the U8903B to simulate aBluetoothtransceiver to receive aBluetoothaudio signal from the DUT and loopback the same signal to the DUT. This ensures that both the uplink and downlink are tested at the same time, simplifying the test setup and reducing test time.
The U8903B is extremely flexible and comes with configurable options. In addition to newBluetoothaudio measurement capabilities, the U8903B offers speech and voice quality measurements, expandable bandwidth and digital audio interfaces, enabling engineers to accurately test wireless communication, component and integrated circuit audio applications.
