This appendix lists the specifications for the SCXI-1521/B modules. These specifications are typical at 25 °C unless otherwise noted. Analog Input Transfer Gain error 1 mV typ 1This is the error after software correction. Gain error is taken into account in the software correction coefficients stored in the onboard EEPROM. These constants are applied automatically when using LabVIEW or NI-DAQmx. 2This is the error before software calibration. Dynamic Minimum scan interval (per channel, any gain in multiplexed mode) Noise RTI1 1Includes excitation voltage noise contribution Filter Stability ±4 ppm /°C typ ±1 µV /°C typ Offset Null Compensation compensation range, 4.4 me resolution for GF = 2.0) Excitation shunt to ground, short circuit protected Bridge Completion Shunt Calibration 7.5 Ω typ Power Requirements (from SCXI Backplane) Physical Maximum Working Voltage Maximum working voltage refers to the signal voltage plus the common-mode voltage.
