Key product information and technical features.
The PXIe-5450 combines arbitrary waveform generation with onboard interpolation, filtering and digital gain. Waveform linking and looping support sequenced signal generation.
Its I/Q outputs can feed an external I/Q modulator. The specified 290 MHz complex baseband bandwidth requires an external modulator; it is not a standalone RF carrier-output specification.
