National Instruments SCXI-1141/SCXI-1142/SCXI-1143 8-Channel Low-Pass Filter Modules

  • Programmable Gain Per Channel (±50 mV to ±5 V Input Range)
  • 8th-Order Programmable Filter Setting Per Module (10 Hz to 25 kHz)
  • 333 kS/s Maximum Sampling Rate (Any Gain)
  • Cascade with SCXI-1140 for Applications Requiring Filtering and Simultaneous Sampling


The National Instruments SCXI-1141, SCXI-1142, and SCXI-1143 are 8-channel, programmable low-pass filter modules, ideal for anti-aliasing applications. You can choose from elliptic, Bessel, or Butterworth filter types. These modules have a common architecture, with a programmable instrumentation amplifier and programmable 8th-order low-pass filter on each channel. While you must set all channels to the same cutoff frequency, you can programmatically bypass the low-pass filter on a per-channel basis. By using a combination of analog filters and switched capacitor filters (SCFs), these modules offer the flexibility of 10,000 discrete software programmable cutoff frequencies while maintaining the low-noise performance of traditional, continuous time-active filters. An external clock input and output are also provided so you can set the filter cutoff frequency with an external clock in tracking filter applications. Each module can condition signals ranging from ±50 mV to ±5 V, and offers multiplexed and parallel modes of operation.
