NI provides several software options for the PXIe-5663E—NI-RFmx, the NI-RFSA instrument driver software, and the NI-RFSA Soft Front Panel (SFP).

Table 1. PXIe-5663E Software Options
Software Option Description Use Case
NI-RFmx

Provides a single-handle instrument driver with built-in measurements.

Use NI-RFmx SpecAn to perform spectral measurements.

Use NI-RFmx Demod to perform modulation quality measurements, such as EVM.

Use NI-RFmx cellular personalities to perform physical layer measurement analysis on supported cellular signals.

NI-RFSA instrument driver

The NI-RFSA APIs each provide a fixed API for interacting with your PXIe-5663E device.

NI-RFSA provides standard IVI-based functionality needed for most vector signal analyzer applications.

Use NI-RFSA to create custom measurements or applications that require I/Q data.

Use NI-RFSA along with the NI Modulation Toolkit to analyze modulated signals to test receivers.

NI-RFSA SFP Controls, analyzes, and presents data similar to stand-alone RF vector signal analyzers. The NI-RFSA SFP operates on the PC, so it provides processing, storage, and display capabilities. Use the NI-RFSA SFP to interactively acquire data.
