Description
The Part Number 189839G-03 refers to a product within the PC-based R Series, specifically the Model PCI-7833. This model, the NI PCI-7833R, is a multifunction Reconfigurable I/O device boasting a 3M Gate capacity. It provides a versatile range of inputs and outputs, featuring 8 Analog Inputs (AI), 8 Analog Outputs (AO), and 96 Digital I/O (DIO).
An important feature of this device is its Programmable FPGA, which allows for user-customizable logic, enabling the device to meet a variety of application-specific requirements. Regarding its analog inputs, the device offers multiple input modes to accommodate different signal requirements. In Differential (DIFF) mode, each channel utilizes two AI lines, allowing for precise measurements by canceling out common-mode noise. In contrast, both Referenced Single-Ended (RSE) and Non-Referenced Single-Ended (NRSE) modes utilize only the positive AI stick of each channel for signal acquisition, suitable for scenarios where differential measurement is not required.
The inclusion of a high impedance instrumentation amplifier in its design facilitates common mode voltage rejection, significantly enhancing measurement accuracy in various application contexts. Additionally, during Analog-to-Digital (A/D) conversions, the device’s ADC Measurement capability ensures precise output voltage readings, critical for data integrity and reliability.
Finally, the Signal Referencing feature of the NI PCI-7833 provides flexibility in signal acquisition, allowing users to reference signals to ground either at the source device or directly at the NI PCI-7833. This flexibility is crucial for accommodating different grounding configurations and minimizing potential ground loop issues.
