The Seven-Band Level Detector block calculates the input signal level, reading directly from the hardware in real time, and displays the level graphically in seven frequency band meter displays:
The level detector performs analysis only and does not modify the input signal. The signal at the output pin is identical to the input.
Use the On / Off button to enable or disable the display. The level detector will not function until the schematic design has been compiled and downloaded to the hardware and a USB communication channel is properly configured.
Note: The refresh rate of the display is approximately 10 Hz. The display's performance is limited by your PC system and USB bandwidth. Using multiple level detectors may degrade the responsiveness.
