The STX104 is a COTS PC/104 8/16-channel 200KSPS 16-bit analog input module that incorporates a very large one million sample FIFO. The STX104 is capable of 200K samples/sec transient data recording using no CPU interrupts.  Optional 2mm connector and cables and analog output amplifiers available, contact factory.

Did you know that the latest Linux Kernel contains an STX104.C kernel module. 

Features and Benefits

  • Analog input ranges: ±10V, ±5V, ±2.5V, ±1.25V, 0-10V,
    0-5V, 0-2.5V, 0-1.25V
  • Triggering Subsystem: 14 start events, 15 stop events, 12 synchronization events, delay timer and three possible triggering sequences.
  • Very Low Noise: Less than 1.5-LSB RMS over all input ranges (1.1-LSB typical). Noise reduction to 0.6-LSB RMS can be achieved using the jumper or software selectable sixteen sample moving average filter.
  • Environmental: Wide operating temperature range of -40oC to +85oC
  • Polarized connectors prevent incorrect cable installations
  • LED status: an LED displays valid card read/write transactions useful for both product development and field status.
  • Single +5V operation: Power less than 1.5 watts
  • Out-gassing and fire avoidance: we do not use any tantalum or electrolytic capacitors in any products.
  • MTBF:  MTBF of 674,355 hours per MIL-HDBK-217F
    ground benign at 25oC.
  • Production: Designed and Assembled in Wisconsin, USA, utilizing an ISO 9001 manufacturing facility.
