|
Low Pass Filter |
Frequency response:
Depends
on the sampling rate. The digital
LP filters have a flat bandwidth of
B = 0.45 x fs and a sharp cut-off
between 0.45 and 0.5 x fs. The exception
is when sampling at 1Hz, then the
bandwidth is 0.2Hz |
| High
Pass Filter |
Frequency response:
Software
selectable for each channel. If activated,
the channel has AC characteristics
with a cut-off frequency below 1Hz.
|
| Power-Line
Notch Filters |
Software
selectable for each channel. If activated,
a notch filter will reject the 50
or 60Hz power line frequencies when
sampling at higher rate than 100Hz |
| Signal
processing |
An
on-board Digital Signal Processor
(DSP) is used for real time signal
conditioning, decimation, filtering,
etc. |
| Signal
resolution |
Depends
on the applied signal processing.
A data word of 16 bits is stored for
each sample. The data word maps ±250mV
when recording DC. The data word maps
±7.8mV when recording AC. |
| Signal
Noise |
Depends
on the applied signal processing.
Noise levels at fs = 200Hz is less
than 1µVrms. Noise levels at fs =
50Hz is less than 0.5µVrms. |
