9.2 Analog inputs

Measurement channels
For each analog channel, several 'subchannels' are available.
Measurement labels with the characters 'raw' show the exact values in mV.
Measurement labels with the characters '_fi' show filtered values.
The word 'name' in the table is a placeholder for the channel's name.

Filtered channels are routed through digital low pass filters:
– C 60 uses A/D converter oversampling and digital filtering to recording rate
– Digital filters eliminate 'out-of-band' noise
– Cut-off frequency automatically adjusted to recording rate
– Linear phase - no signal distortion
– Latency compensation - no filter delay in recorded data
