 Channels
|
|
All settings can be entered independently for each channel. For example, you may use different filters. The number of tabs depends on the number of active channels.
|
|
|
More settings are available when right-clicking on the channel. Thereby its color in the diagram can be adjusted (Change color) or its settings can be transferred to other channels (Copy settings to other channels).

 Signal input
|
|
Selects the physical input and the gain of the USB device.

 Measurand and unit
The connected sensor determines the available options. Velocity and displacement are calculated from acceleration by integration (VM-FFT+ only).
The unit should be selected in a way that the measuring value does not drop below 0.001 permanently.

 Characteristic
The following characteristics are available:
|
Peak value
|
The height of the FFT line represents the amplitude of the corresponding sinusoidal signal.
|
|
True RMS value
|
The height of the FFT line represents the true RMS value of the corresponding sinusoidal signal.
|
|
Peak-to-peak value
|
The height of the FFT line represents the peak-to-peak amplitude of the corresponding sinusoidal signal.
