  • Page 18: Low-Pass Filter

    Scroll through all enabled channels with the Next and Previous buttons. Low-pass Filter Each analog channel employs a low-pass filter with automatic corner frequency selection. The filter is a CIC (cas- caded integrator comb) type that uses as many as 512 samples per channel to calculate in real time as data is acquired. Filter response is optimized when sampling frequency is set to ten times the highest frequency of interest.

  • Page 19: Digital Ports

    Digital Ports The DI-4108 and DI-4208 contain 7 general-purpose digital ports. Each digital port can be configured as a digital input or used as a switch to control an external load (up to 25 V and 100 mA). Many of the ports also provide specific func- tionality in W or a third-party program.
