When this option is selected, two new markers labeled AWM1 and AWM2 appears on the FFT plot when using the GUI in Single Tone mode only. All of the calculated AC performance statistics in the left column only uses the captured values between these window markers for the calculations. The default location of marker AWM1 is at 0 MHz and marker AWM2 is at ½ the ADC sample rate (Nyquist). The location of these markers can be set either by entering a frequency value (in Hertz) in the AWM1 and AWM2 location boxes located in the bottom left corner of the GUI or by clicking on the markers directly and dragging them with the computer mouse. The AC parameters update immediately after the markers have been moved. Figure 3-20 shows an example of the Analysis Window Markers being used to display AC parameters inside a 90-MHz analysis window centered around a 70-MHz tone inside the FFT.
