8<p>This panel allows you to set levels for loopback signals</p>
9<p>The process is as follows:</p>
10<ol>
11    <li>Select the input and output devices on which the loopback is executing.</li>
12    <li>Click "Left" to play a sine wave on the left channel of the selected output device.</li>
13    <li>Use the volume control on the DUT and/or external peripheral to set an appropriate signal level.</li>
14    <li>Repeat the process for the right channel.
15</ol>
16<p>The signal level for the Left signal should look something like this:</p>

18<p>The signal level for the Right signal should look something like this:</p>
19<center><img src="images/LoopbackCalRight.png" alt="A right-channel loopback example." style="width:200px;height:150px;"></center>
