PXI-5671 Overview
The PXI-5671 Vector Signal Generator consists of the following two PXI hardware modules:
- PXI-5441 Waveform Generator—16 bit, 100 MS/s arbitrary waveform generator (AWG) PXI module (400 MS/s interpolated) with digital upconverter (DUC)
- PXI-5610 RF Signal Upconverter—2.7 GHz RF superheterodyne upconverter PXI module
The PXI-5671 has the following characteristics and features:
- 250 kHz to 2.7 GHz frequency range
- -145 dBm to +10 dBm amplitude range
- 20 MHz instantaneous bandwidth with DUC disabled, 6.6 MHz with DUC enabled
- 10 MHz oven-controlled crystal oscillator (OCXO) timebase with ±20 ppb frequency stability, ±50 ppb frequency accuracy
- 132 dB compression-to-noise dynamic range
- -120 dBm/Hz typical noise density (0 dBm output level, 15 °C to 35 °C)
- ≥512 MB of AWG module onboard waveform memory
- NI-RFSG instrument driver software transparently operates both modules as a single unit
- Three-slot wide PXI/3U CompactPCI form factor
The PXI-5671 follows industry-standard Plug&Play specifications for the PXI bus and allows seamless integration with compliant systems.
The PXI-5671 hardware modules interconnect using SMA-SMB coaxial cables, included in your hardware kit, as illustrated in the following figure. Refer to the PXI-5671 Getting Started Guide for more information about interconnecting hardware modules.

- Digital Upconverter
A digital upconverter (DUC) accepts a complex I/Q waveform as its input. The DUC then converts this complex waveform to a real waveform with the same frequency content but centered at a higher IF center frequency. In other words, the baseband signal is "upconverted" to IF, and this upconversion is done digitally in DUC firmware.
