Spectrum Analyzer Mode Functions
if the FFT mode is already active, pressing FFT MARKERS only activates the FFT markers. If the FFT mode is not active, then the FFT marker will be activated and the FFT annotation will be displayed but an FFT will not be performed. Pressing the % AM ON OFF key will give a valid
value for the signal in trace B. Press FFT OFF to return the analyzer to normal operation.
An FFT trace can be saved and recalled. If a trace has been recalled, FFT MARKERS can be used to activate the markers so that the trace can be evaluated.
accesses the menu of keys to initiate and evaluate a Fourier transform of the analyzer displayed data. Activating other analyzer functions will automatically exit the FFT function or will corrupt the display. See Table
