♦ DC-Signal path (DC coupled processing path)
This signal path has continuous access to the entire raw signal,
including the available DC voltage part of the signal.
In this path also the DC-operating point (sensor passive voltage)
resulting from the sensor power supply is acquired and monitored
(sensor OK-monitoring). An error-free measurement chain is
signalled through an OK LED on the front panel of the V-TIM.
♦ AC-path (AC coupled processing path)
This signal path has access only to the AC part of the raw sensor
signal. The dynamics of the processing can thus be used
completely for the vibration measurement. As a result the velocity
signal from a connected sensor can be evaluated with maximum
resolution and accuracy.
The input range of the AC signal path is continuously monitored for
signal over-ranging. When over-ranging of an A/D converter occurs
this is signalled by a red LED on the front of the V-TIM.
