Description
The 778745-4220 is a high-performance data acquisition device belonging to the SCXI & Legacy category, specifically modeled as PXI-4220. This device is equipped with 2 channels and boasts a 16-Bit resolution, ensuring precise data capture. It is capable of a maximum sampling rate of 333 kS/s, making it suitable for a wide range of high-speed measurement applications.
The PXI-4220 is designed for strain/bridge input type measurements, with an excitation voltage adjustment that is software-selectable on pins 2 and 7. This feature provides flexibility in configuring the device for various types of sensors. Additionally, it offers multiple lowpass filter cutoff frequency options, including 10 Hz, 100 Hz, 1 kHz, 10 kHz, and an option to disable the filter. Each channel employs a 4-pole Butterworth filter, ensuring smooth signal processing.
For timing and synchronization, the device can utilize an external time base via the PXI trigger bus or an internal 20 MHz time base. The PXI trigger bus includes 1 star trigger and 6 trigger lines, providing extensive integration capabilities within a PXI system. The amplifier input impedance is greater than 1 GΩ, and the maximum input bias current is ±20 nA, highlighting the device’s ability to handle high-impedance sources with minimal error.
Compatibility with driver software NIDAQmx (version 7.0 or later) and compatible ADEs such as LabVIEW, LabWindows/CVI, and Measurement Studio, makes the PXI-4220 a versatile solution for a wide range of data acquisition and signal processing tasks. The device dimensions are 6.3 x 3.9 x 0.79 inches, making it compact enough for easy integration into PXI systems.
