Overview

Product overview

Key product information and technical features.

The PXIe-5663E combines RF downconversion and IF digitization in a modular analyzer architecture. NI's configuration guidance identifies the PXIe-5601 RF downconverter, PXIe-5622 IF digitizer, and PXIe-5652 local-oscillator source for the 6.6 GHz system.

The model name covers multiple frequency and memory configurations. NI lists 781260-01 as 6.6 GHz with 64 MB RAM, whereas the 3.4 GHz, 64 MB configuration is 781259-01. Confirm the assembly identification before treating the legacy frequency description as applicable to this catalog record.
