In addition, the OROS FFT spectrum analyzer is equipped with a control panel function that allows users to save frequently used measurement settings for quick access. By using this function, all settings can be changed on the [[NVGate_Control_Panel|control panel]]. For example, the following is the setting screen for a hammer test. By saving the input settings, threshold settings, and FFT analysis settings to the control panel as shown below, it is possible to make all the necessary settings quickly by only using the control panel. | In addition, the OROS FFT spectrum analyzer is equipped with a control panel function that allows users to save frequently used measurement settings for quick access.

In the prototype of a small diesel engine, there is a problem that the rotational torsional vibration of the timing belt and the camshaft resonates, causing a large vibration. By measuring rotational fluctuations and rotational twists with high accuracy using the six tachometer channels mounted on the OROS FFT analyzer, it is clarified which rotational order is dominant for vibration.<br> | In the prototype of a small diesel engine, there is a problem that the rotational torsional vibration of the timing belt and the camshaft resonates, causing a large vibration.
