Use SCXI Advisor to configure an SCXI data acquisition system based on this module.

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

The SCXI-1600USB data acquisition module can be used in conjunction with this module to create a completely plug-and-play USB data acquisition system. An SCXI chassis is required to house the SCXI-1600 and assorted SCXI modules for a particular system. The SCXI-1000 chassis is capable of holding up to four modules while the SCXI-1001 can hold up to 12.
