4.2.2. Bottom noise scanning

The Uplink Bottom Noise Scan page is shown in Figure 4-3. Scanning the bottom noise through

the Uplink is divided into three steps:

Step 1: Set the scan interval and scan duration.

Step 2: Set the path to save the data files.

Step 3: Click "Start Scan".

The noise data is stored as a folder in the set file path with a timestamp added to the folder name
