The NI PXIe-5450 is a dual-channel, 16-bit arbitrary waveform generator module engineered for high-performance baseband and I/Q signal generation. It delivers up to 400 MS/s sample rates across a 145 MHz bandwidth, with configurable onboard waveform memory up to 2 GB. The module integrates signal processing functions including pulse shaping, interpolation filtering, gain/offset control, and a numerically controlled oscillator for frequency shifting—eliminating the need for external baseband components in RF vector signal generator architectures.
