Overview

Product overview

Key product information and technical features.

The PXI-5441 generates user-defined arbitrary waveforms and standard sine, square, triangle, and ramp functions. It combines waveform generation with onboard processing rather than relying solely on stored waveform playback.

Processing functions include FIR and CIC interpolation filters, digital prefilter gain, a numerically controlled oscillator, and I/Q mixing. Synchronization features include locking to external clocks or PXI_CLK10 and TClk synchronization.

Quadrature digital upconversion using onboard I/Q mixing and a numerically controlled oscillator.
FIR and CIC interpolation filters with digital prefilter gain.
Waveform linking and looping for arbitrary waveform generation.
Software-selectable 50 Ω or 75 Ω output impedance.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the PXI-5441 support digital upconversion?

Yes. Its onboard processing includes a numerically controlled oscillator and I/Q mixing for quadrature digital upconversion, along with FIR and CIC interpolation filters.

How much waveform memory does this unit have?

The installed memory has not been established for this catalog unit. NI lists 32 MB, 256 MB, and 512 MB PXI-5441 variants; confirm the exact hardware option before selecting it for a waveform-storage requirement.

Which driver family supports the PXI-5441?

NI-FGEN supports the PXI-5441. Check the selected driver's release documentation for operating-system and development-environment requirements.
