End user installs between 1 and 6 filter daughterboards onto each
card, one daughterboard per channel, and installs between 1 and 14 cards
into each i4xx card cage.
Filters can be used to digitize waveforms into Windows Computer, or can
be used independently due to both filter
at Hd44 connector.
analog filter provides extremely low ±0.01dB maximum passband
ripple for Fin/Fc ≤ 0.5.
If one uses further
oversampling, digital filtering and
desampling; then passband ripple
is ±0.002dB for Fin/Fc ≤
0.8 due to the accuracy of a 30-pole digital filter.
analog filter provides stopband
attenuation of ≥ 76dB for Fin/Fc ≥ 3
strip chart recorder software; or purchase powerful
4 different filter products, each with different cut off frequencies:
380Hz, 1KHz, 3.3KHz, 10KHz. However, further digital processing provides
other cutoff frequencies lower than these. For example,
with an i500
Fc=1KHz analog filter one can digitize at
ANY sample rate
less than 2Ks/sec/channel and have a DIGITAL
low pass filter provide anti-aliasing.
Signal first passes through
signal conditioning amplifier before reaching
i500 analog filter;
therefore, one can attach directly to the following sensors:
Digitize any combination of channels at 166,000 samples-per-second aggregate
