The test results will be displayed for each test frequency for each band. The results will also be displayed in
the <Commissioning Tool> table when you navigate to <Device Sites & Channels Site>. The device will
use the Lowest Isolation measured for each band to limit the BDA Gains according to the code requirement to
provide 20dB margin between BDA Gain and Isolation.
You can reset the measurements at any time by clicking on <Reset>.
Example (See Figure 125 below): Lowest Isolation Measured: 100dB
MAX BDA Gain = Isolation - 20dB = 100dB - 20dB = 80dB
