Real Time Spectrograph : Parameters > Buffer Size
|
|
The list box Buffer size [kBytes] defines the size of the circular buffer used for saving the recorded data. The buffer size determines the Buffer duration of recorded data depending on the selected sampling rate.
The Refreshing interval [%] determines how often the real-time spectrogram display is being updated.
The option Enable USG DI trigger activates the digital input of the Avisoft-UltraSoundGate for transferring the buffer contents into the main window. If activated, an active-low signal at the DI will execute the command Transfer buffer into Main Window. This option should not be activated when using other soundcards than the Avisoft-UltraSoundGate.
If the option Enable Joystick button #1 / #5 / USG button is activated, the circular buffer content will be transferred into the main window by pressing button #1 or #5 of a joystick (or the TRIGGER button on an UltraSoundGate device).
The Default button sets the default values for these parameters.
