Overview

Product overview

Key product information and technical features.

The PXIe-5665 integrates separate RF downconverter, synthesizer/local-oscillator, and IF digitizer modules into one analyzer system.

NI documents both 3.6 GHz and 14 GHz configurations. The catalog tag and legacy description identify different configurations, so neither set of option-dependent specifications is presented as confirmed for this record.

RF list mode support.
Documented phase-coherent MIMO configurations using additional analyzer channels and shared LO/reference signals.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the PXIe-5665 a single module?

No. It is an analyzer system assembled from separate downconverter, LO, and IF digitizer modules.

Does this record confirm the 781428-04 configuration?

No. That number appears in the catalog tags, but NI identifies it as a 14 GHz, 50 MHz bandwidth, 256 MB configuration with preamplifier and YTF. This conflicts with the legacy description; assembly identification is required.

How are the digitizer and LO synchronized?

The default arrangement exports the PXIe-5653 internal 100 MHz reference to the PXIe-5622, frequency-locking the two modules.
