Keysight (Agilent) U8903B Performance Audio Analyzer
Make multi-functional and higher performance audio measurements with the Keysight U8903B audio analyzer. With extremely low residual distortion of < -110 dB, the U8903B allows you to measure the most demanding audio devices with high accuracy. Perform audio measurements via a Bluetooth link with the new Bluetooth option, and make the highest resolution two-channel measurements available when you expand your bandwidth to 1.5 MHz. Ensure the quality of your Bluetooth link and easily troubleshoot connection issues with two functions designed for the Bluetooth option: the received power indicator and bit error rate measurement.
The Keysight U8903B audio analyzer comes with local loopback capability to provide fast, accurate loopback testing of Bluetooth chipsets, modules and devices. The loopback capability allows the uplink signal to be looped back at the U8903B 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. The U8903B audio analyzer can be configured to 4 or 8 analog analyzer channels. The instrument is capable of simultaneous measurement, on all channels, making the Keysight U8903B the ideal choice for multichannel systems such as 5.1 or 7.1 surround sound.
Specifications for the Keysight (Agilent) U8903B Performance Audio Analyzer Include:
| Maximum Analysis Bandwidth | 1.5 MHz |
| Overall Amplitude Accuracy | ±0.03 dB |
| Number of Channels | 2, 4 or 8 |
