PXI Waveform Generator

PXIe, 145 MHz Bandwidth, 2-Channel, 16-Bit PXI Waveform Generator—The PXIe‑5451 is a 145 MHz, dual‐channel arbitrary waveform generator capable of generating user-definied waveforms, standard functions, and I/Q communications signals. It is an ideal instrument for including in systems for testing devices with I/Q inputs, or as the baseband component of an RF vector signal generator as well as time-domain signals like envelope tracking. The PXIe‑5451 also features onboard signal processing (OSP) functions that include pulse shaping and interpolation filters, gain and offset control, and a numerically controlled oscillator (NCO) for frequency shifting. The PXIe‑5451 also features advanced synchronization and data streaming capabilities.
