The National Instruments PXI-5122EX is a high-performance 14-bit digitizer designed for demanding applications across communications, automotive testing, consumer electronics, and scientific research. This model features dual channels that operate simultaneously at 100 MS/s, offering a bandwidth of 100 MHz and an impressive 62 dB signal-to-noise ratio (SNR) along with a spurious-free dynamic range of up to 75 dBc. The PXI-5122EX is equipped with 8 MB of memory per channel, allowing for the acquisition and management of approximately 4 million samples at 14 bits, making it suitable for continuous data streaming directly from onboard memory to host memory for extended measurement sessions.

This digitizer provides flexible input impedance options, selectable via software for either 50 Ω or 1 MΩ configurations, and supports a wide input range from 200 mVpp to 20 Vpp. The triggering capabilities of the PXI-5122EX include three sources: software control, analog, and digital, along with pretrigger and posttrigger options beneficial for advanced recording modes. A programmable DC offset feature optimizes the vertical range usage, while integrated self-calibration ensures measurement accuracy and stability across the device’s full operating temperature range. The PXI-5122EX distinguishes itself from the PXI-5122 with the additional functionality of enabling minimal firmware custom logic modification by users, while maintaining the same specifications. Dimensions are 8.5 × 0.8 × 5.1 inches, and it weighs 13.5 ounces. For more information, including warranty details and to download user manuals, please contact a sales representative for a quote.
