National Instruments 781369-01 Dynamic Signal Acquisition Device
The part number 781369-01 from National Instruments is the identifying part number for the PXIe-4497 Dynamic Signal Acquisition device. This device features 16 pseudo differential input channels and the users can select the AC or DC coupling per channel. The device features a 24-bit delta-sigma analog-to-digital converter for each channel, to help convert the analog signal to a high-resolution and accurate digital signal for processing.
This module's sampling rates from 100 S/s to 204.8 kS/s, with a resolution of ≤181.9 μS/s, helping acquire accurate and precise data. The device has a FIFO buffer size of 4,095 samples which helps with efficient data transfer. This module can handle input voltages with respect to the chassis ground of up to ±30 Volts on the positive terminal and ±5 Volts on the negative terminal.
The AC-coupled measurement accuracy for the 781369-01 is characterized by a gain amplitude accuracy of 0.05 dB maximum within 5 degrees Celsius of the last self-calibration temperature, and 0.1 dB maximum over the full operating temperature range. The DC-coupled measurement accuracy is defined by a gain amplitude accuracy of 0.5% maximum within 5 degrees Celsius of the last self-calibration temperature, and 1% maximum over the full operating temperature range.
The power requirements for the 781369-01 include a +3.3 Volts supply at 2100 mA and a +12 Volts supply at 810 mA. It has an ambient temperature range of 0 degrees Celsius to 55 degrees Celsius and supports a relative humidity range of 10% to 90%, noncondensing. The device is designed for indoor use and is rated for a maximum altitude of 2,000 meters. The 781369-01 is housed in a 3U PXI Express module form factor, with dimensions of 16 cm × 10 cm (6.3 in. × 3.9 in.), and weighs approximately 326 g (11.5 oz) making it compact and portable and also easier to maintain. This module should only be operated indoors as it does not feature an Ingress protection rating and may get affected by dust and moisture which may affect the overall performance of the module and long term reliability.
