9.4 Digital Inputs
- Quantity: 4, of which 2 are for frequency measurements (Channels Q and R)
- Trigger threshold: approx. 2 V
- Dynamics: 30 kHz
9.5 Measurement Channels
A total of up to 32 measurement channels can be processed by the CMU.
One measurement channel can be a value of a connected sensor (also a subchannel
or a SMART sensor) or a value derived (calculated) from sensor data.
