Signal input

 
1. Signal input
 
Signal source selects the physical input for the vibration signal in X and Y direction. Gain is used for the manual range selection.

Measurand and unit

 
2. Measurand and unit
For the filtered signal a measurand is selected. The sensor linked to the measurement channel determines this measurand. Additionally, VM-SCOPE+ can manage the integrated measurands. Therefore it offers vibration velocity and displacement when linked to an accelerometer.
The units are listed matching the measurand. The characteristic value should neither rise above 10 000 nor fall below 0.001 permanently. This should be noted while selecting a unit.

Bandpass filter

 
3. Bandpass filter
Signals receive a bandwidth limit by a filter. Frequencies below fmin and above fmax are hidden. The operating frequency between fmin and fmax remains.
