The PCIDAQ 3210 can acquire 32 single-ended (or 16 differential) channels of
data at up to 100kHz (100,000 samples/second) with 12-bit resolution.
The board features software-programmable gains, a 1024-sample FIFO buffer,
and 2500 Vrms of isolation on its analog input channels.
The 100kHz board can accurately sample signals whose frequency is below
50kHz. If your signal has high-frequency components which are not relevant, the
low-pass filter on the PCIDAQ 3210 can help ensure that the signal of interest
is sampled by only allowing through signals in the desired frequency range.
