The National Instruments SCXI-1126 is a signal conditioning module with eight isolated frequency input channels. Each channel of the NI SCXI-1126 includes a frequency-to-voltage conversion circuit with programmable input range, threshold, hysteresis, and filtering. The SCXI-1126 can measure the frequency of analog and digital signals with voltage levels as high as 1,000 VDC. The output voltages of the SCXI-1126 module are multiplexed onto a single channel of a DAQ device, so one can scan and acquire multiple frequency and analog input signals within a single high-speed scan operation.
