If you tap the frequency display monitor, it is possible to use the keyboard. In the keyboard input, you should set a frequency of 20000Hz from 20Hz.

It should be noted that the initial application startup, the initial value does not set, it need to set an integer value of frequency.

Further, by tapping a preset frequency button can be set from four preset types. By tapping "PLAY" button in the control area, it generates a tone signal. It stops the signal generation by tapping "STOP" button.

Sweep Mode

This is the Sinewave Sweep signal generation mode.

It generates a sine wave of transitional frequency continuously in the frequency range of 20000Hz from 20Hz.

If you tap the frequency monitor display, it is possible to use the keyboard. In the keyboard input, you should set both the upper and lower limit frequency. It should note that the initial value is not set at the application startup, it need to set the integer value of both frequency.

In addition, by tapping a preset button, you can set from two types. There is two types of "PLAY" button that can be generated rising sweep and downward sweep. It generates a tone signal sweep by tapping "PLAY" button in the control area, and then sweep the full frequency range at 60 seconds. It stops the signal generation by tapping "STOP" button.
