Overview

Product overview

Key product information and technical features.

In the NI 449x specifications, the PXIe-4498 is documented as having 16 simultaneously sampled input channels, a pseudodifferential input configuration, and 50 Ω between the negative input and chassis ground. The same NI specification document distinguishes PXIe-4498 from PXI-4498 by interface family and lists the PXIe mechanical format as a PXI Express 3U CompactPCI slot. https://docs-be.ni.com/bundle/ni-449x-specs/raw/resource/enus/372125f.pdf

NI specifies four gain settings for the 4498/4499 family: 30 dB, 20 dB, 10 dB, and 0 dB. The NI 449x specifications also state that all device inputs except NI 4495 support IEEE 1451 TEDS, which includes PXIe-4498, and that IEPE excitation is software selectable per channel at 0 or 4 mA ±10% with 24 V compliance. https://docs-be.ni.com/bundle/ni-449x-specs/raw/resource/enus/372125f.pdf

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is PXIe-4498 the same as PXI-4498?

No. NI documents PXI-4498 and PXIe-4498 separately within the 449x specifications, including different platform/interface families and separate power requirements. The PXIe-4498 is the PXI Express version.

How many input channels does the PXIe-4498 provide?

NI specifies 16 simultaneously sampled input channels for the PXIe-4498.

Does the PXIe-4498 support DC coupling?

No. NI identifies the PXIe-4498 as AC-coupled.

Does the PXIe-4498 support IEPE sensors and TEDS?

Yes. NI specifies software-selectable IEPE excitation of 0 or 4 mA ±10% per channel with 24 V compliance, and the NI 449x specifications state that all device inputs except NI 4495 support IEEE 1451 TEDS, which includes PXIe-4498.
