Overview

Product overview

Key product information and technical features.

The PXI-5922 uses NI Flex II ADC technology to trade sampling speed for resolution. This architecture supports dynamic measurements such as audio analysis and spectrum analysis.

NI lists three memory variants: 8 MB per channel for 779153-01, 32 MB per channel for 779153-02, and 256 MB per channel for 779153-03. The supplied catalog record does not establish the installed memory variant.

  • Flex II ADC architecture provides sample-rate-dependent measurement resolution.
  • Integrated antialias filtering provides an alias-free bandwidth of 0.4 times the sampling rate.
  • SMC architecture supports T-Clock synchronization with other SMC-based modular instruments.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the PXI-5922 provide 24-bit resolution at 15 MS/s?

No. NI specifies 24-bit resolution at 50 and 500 kS/s and 16-bit resolution at 15 MS/s.

Is 779659-02 a PXI-5922 part number?

No. NI identifies 779659-02 as a PCI-5922 variant, not a PXI-5922 module.
