NI PXI-5411 High-Speed Arbitrary Waveform Generator

The NI PXI-5411 is a high-speed arbitrary waveform generator module for PXI systems that delivers precise custom signal creation across demanding test and measurement applications. Operating at 12-bit resolution with a 40 MHz maximum update rate, this module generates arbitrary waveforms, standard functions (sine, square, triangle, ramp), and complex signal sequences. Output ranges from ±5 V into 50 Ω loads or ±10 V into high-impedance loads, with a 32-bit DDS accumulator enabling fine frequency control. The device stores up to 2,000,000 16-bit samples in arbitrary waveform mode, supporting continuous, stepped, single, and burst operational modes.
