Description
The National Instruments PXI-5122EX Digitizer is a high-performance data acquisition tool with a 100 MHz bandwidth and 8 MB of memory depth per channel. With its 14-bit resolution and two simultaneously sampled channels, it provides precise measurements at a maximum sampling rate of 100 MS/s. The digitizer boasts a 62 dB signal-to-noise ratio (SNR) and a 75 dBc spurious-free dynamic range (SFDR), ensuring high-quality data capture.
Flexible input impedance options are available, with 50 Ω or 1 MΩ (software-selectable), while the input range can handle from 200 mVpp to 20 Vpp. The device features seven different trigger modes and supports various trigger sources including software control, analog, and digital. Additionally, pretrigger and posttrigger settings enhance its functionality in multiple record modes.
An important feature of the PXI-5122EX is the included programmable DC offset, which expands the usable vertical range. To maintain accuracy and reliability, an integrated self-calibration function ensures measurement stability across the operating temperature range. Although the acquisition memory capacity is not specified in the provided table, the high memory depth implies the ability to handle large amounts of data, which is crucial for complicated and lengthy measurements.
