 Data Sheet |
Configure System 
National Instruments recommends M Series DAQ and NI-DAQmx driver software for new applications. Increase resolution 16 times, double sampling speeds, get more I/O, and improve performance with the 16-bit, 1.25 MS/s PXI-6251.
Add sensor and high-voltage measurement capability to your E Series device with NI SCC or SCXI signal conditioning. The National Instruments PXI-6040E uses E Series technology to deliver high-performance, reliable data acquisition capabilities to meet a wide range of application requirements. You get 500 kS/s (1-channel, 250 kS/s multichannel), 12-bit resolution on 16 single-ended analog inputs. Depending on your type of hard drive, this module can stream to disk at rates up to 250 kS/s. Using NI hardware, you have flexible OS, application development environment, and application software choices.
Complete your DAQ system with NI signal conditioning to measure virtually any type of sensor and voltage.
