5.4 Gain Setting
The default gain for each channel is set to 0dB. MA 850A enables the authorized user (admin
level) to adjust the gain for every channel to counteract changes in the environment.
For example, you may want to reduce the coverage area of a channel to prevent interference.
Or, the output of an AP with a low power (<20dBm) can be increased using the gain value.
To change the gain setting of a channel
1. Click the Setting button in the Main window. The Gain Setting options appear.
