FM MENU DISPLAY SETTINGS
The Decay Rate control adjusts how quickly the display will fall after a peak is displayed. Lower settings are the slowest,
♦
while the highest setting is instantaneous.
The Peak Hold control enables or disables the ability to indicate and hold the highest peak achieved. Peak Hold is
♦
displayed in the dark green background layer.
The X-Center control centers the display at the selected frequency.
♦
The X-Width control sets the displayed frequency range in kHz.
♦
The Y-Center control centers the display vertically around the selected level in dB.
♦
The Y-Range control sets the displayed level range in dB.
♦
The dB Scale Position control allows you to move the dB scale horizontally to a different place in the display. Advancing
♦
the control completely to the right places it in front of the graph at all times.
Below are some examples of how to use the FFT menu:
