DISPLAY AND METER OPTIONS
Instrumentation Menu > FFT Spectrum Analyzer Menu
The
FFT
menu allows you to monitor the same sources as those mentioned in the Oscilloscope menu section.
♦
The
Delay
control works the same here as it does previous and subsequent display sections.
♦
The
Resolution
control selects the number of frequency bands into which the audio is divided. 1x
resolution gives you a refresh rate of approximately 48 frames per second and a frequency resolution
sufficient for viewing the entire audio spectrum. 8x resolutions gives you a refresh rate of approximately 6
frames per second, but a much finer frequency resolution.
♦
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.
Meter Options
The
Meter Options
submenu appears as an option in the AM, Studio Processing, HD and Streaming menus.
Loudness Meters Menu
Which meters are displayed in the Loudness Meter display window are determined by enabling or disabling
available options in this menu.
Specifically:
♦
Program Input, Output
and
Test Input
can be displayed.
♦
The
Loudness Graph
can be added to the Short Term and Momentary graphing displays.
