Hi I'm Hock Eng from Keysight Technologies.
Today I'm going to show you the new Bluetooth option for the U8903B performance audio analyzer.
This Bluetooth option provides a Bluetooth link for you to test any Bluetooth audio device,
whether it's a receiver or transmitter.
The Bluetooth link for this audio analyzer either can be configured over the air using a simple RF antenna,
or through a direct RF cable,
and in this video, I'm going to show both of these two methods of connection.
And now I’m going to show you how to set up the Bluetooth link on the U8903B.
On the front panel the default generator is always the analog generator.
In order to change it to the Bluetooth generator, simply press the Interface button twice,
and it will change to the Bluetooth generator as shown over here.
Then, go to the Link Config and do device scan.
Change the maximum scan to one in order to hasten the scanning, and then press the Device Search button.
The U8903B has found the device under test over here.
And the next step is to pair the device under test.
Under Device Action, pair the device.
Once the pair is complete, it will show here as Yes in the Paired column.
Then under the profile connection, choose the connect to A2DP,
and finally open the media connection of the A2DP.
And on the Config Link page over here, you can see the codec used under the device under test and also the sampling rate, which is used.
Turn on the Bluetooth generator, which is shown over here, ON,
and then on the analyzer side, turn it on and now the analog analyzer of the U8903B is measuring 1 kHz.
Now let’s do a frequency sweep on the device under test.
Press the Sweep hardkey, and then remember to change it to the BT generator,
and then press the On button to start the sweeping.
Once the Sweeping is completed, you will see a frequency response plot as shown.
Now the device under test is connected through a cable to the U8903B.
And the device under test has been connected and paired successfully,
and I will turn on the Bluetooth generator right now, and also the analog analyzer as well.
And it shows almost the same result as the one using the RF antenna.
And I’ll do a frequency sweep again using the sweep button.
I have already changed the generator to the Bluetooth generator, and let’s start the sweeping.
The frequency response plot is almost similar to the one using RF antenna.
I’ve shown you how relatively easy it is to perform a Bluetooth audio measurement using the Bluetooth option for the U8903B audio analyzer.
Basically you have to search, pair, connect and then open the media to start streaming the data.

Thank you for watching.
