This dialog box is used to set the maximum frequency for the spectrum analyser. This function is duplicated on the spectrum analyser toolbar.

Max frequency
The maximum frequency controls the sampling rate of the data collected for spectrum analysis. This, in turn, determines the highest frequency that the spectrum analyser can display.

Note: The lower the maximum frequency, the longer it takes to collect enough data to display a spectrum. At very low maximum frequencies, this may affect the response time of your computer to keyboard input.

X multiplier
When the X multiplier is 1, the computer displays the entire frequency range across the full width of the window. If you change the X multiplier to x2, the computer displays only half of the frequency range, but twice as big. It also displays a scroll bar across the bottom of the window which you can use to control the frequency range that is displayed.
