Use SCXI Advisor to configure an SCXI data acquisition system based on this module.
The National Instruments SCXI-1140 is an 8-channel simultaneous-sampling differential amplifier module. Each channel contains a high-input-impedance instrumentation amplifier with switch-selectable gain followed by a track-and-hold (T/H) amplifier. The T/H amplifiers track simultaneously, which is useful for preserving interchannel phase relationships. You can run the T/H outputs to eight different input channels on the DAQ device, or you can multiplex the output of one or more modules into one channel of the DAQ device.
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.
