4. View the 10th peak power channel set.
3. Press the Extract Selected button. The file is stored in a user selected file location as shown in Figure: Stores File with (10) to Identify Power Channel Extracted. In this example, the file is stored in the same location of the original file. The original file (80 MHz.dgz) is >33 GB in size. In comparison, and as a result of using the Time Resolution slider to find the peaks of the signal in 5 ms resolution, the 32 GB file is now a time slice of ~180 MB in size.
