The frequency analyser showes the frequency spectrum of the source, either separately for both channels or together. Roughly speaking the XY scope draws a plots where the left channel is used for the x axis and the right channel for the y axis. Thus a audio signal only present on the left channel produces a horizontal line, whereas a audio signal only present on the right channel produces a vertical line. Can be used as a PC-Based RTA.
