Audio Analyzer with Bluetooth: UB Microwave Journal

This gives users a quick and Keysight U8903B Audio Analyzer way to check that the Bluetooth-RF link is strong enough. By monitoring changes in the BER value, engineers can determine the causes of the link quality deterioration. The loopback capability allows the uplink signal to be looped back at the UB and sent to the DUT, ensuring that both the uplink and downlink are tested at the same time. Without this feature, engineers will need to test the uplink and downlink separately, which would double the test time and require more wiring.

Loopback testing is applicable to Bluetooth module design or mobile devices which require a validation of its Bluetooth audio quality in both uplink and downlink communications. The feature provides highly accurate measurements as there is no potential audio degradation by the UB's internal audio signal processing.

Users also receive the full functions of audio measurement, with the tests processed in the analog audio domain, not the Bluetooth domain. Example of a loopback test case measuring the Bluetooth audio quality of a mobile phone.

This option is ideal for looking at the spectrum from Class D amplifiers or switching supplies where frequency components or noise well above the audio band can have a detrimental effect on audio quality.
