The NI 5752 is a 32-channel digitizer adapter module that can sample on all channels at 50 MS/s with 12-bit resolution. With 100 Ω differential inputs, AC coupling, and built-in analog-to-digital converter (ADC) features such as selectable antialias filters and programmable time-variable gain control, this module is optimized for nondestructive test (NDT) and ultrasound applications.
When coupled to an NI FlexRIO field-programmable gate array (FPGA) module, the NI 5752 helps you implement your own high-speed control and inline processing algorithms, including fast Fourier transforms (FFTs), filtering, peak detection, and gating, in the FPGA. You can synchronize multiple modules for higher-channel-count systems and use the module’s 16 digital outputs to interface to external power amplifiers to create an array of high-voltage pulser channels with per-channel phase control. Note that for certain NDT applications, you may need to add more signal conditioning and input protection circuitry.
