The digital control circuitry contains a Module ID (identification) register, a configuration register for the module, a gain register, and an EEPROM for storing gain-calibration constants. The Module ID register contains 20 (hex) for the SCXI-1141 module, 35 (hex) for the SCXI-1142 module, and 34 (hex) for the SCXI-1143 module. You can read this module ID over the SCXIbus to determine the type of module that is in a particular slot. Use the configuration register to select channels and configure the SCXI-1141/1142/1143 module for scanning, calibration, and control options. The gain register sets the gain of each amplifier. The frequency dividers control the filter cutoff frequency and the output clock frequency. For more information see the Using the External Clock Input section. The EEPROM stores the calibration constants for each gain for all eight channels. Information in the EEPROM is retained when the module is power off. The SCXI-1141/1142/1143 module has calibration constants already stored in the EEPROM. You can modify these constants for your set of operating conditions. One set of constants is reserved and cannot be modified except at the factory, which ensures that you do not accidentally erase the default calibration constants. For more information on the EEPROM and calibration, see Chapter 5, Using the SCXI-1141/1142/1143 Module. Input Amplifiers The amplifiers provide gain to the differential signal between the inputs while rejecting common-mode noise voltages. The available gains are 1, 2, 5, 10, 20, 50, and 100. The output range of the amplifiers is ±5 V. Select the gain to prevent the output signals from reaching ±5 V, or distortion occurs. The input amplifiers are fully differential amplifiers with input protection and calibration circuitry. The inputs are protected against input volt
