CALIBRATION PROCEDURE
NI PXIe-4464
4-Channel, 204.8 kS/s DSA Input
This document contains the verification and adjustment procedures for the National Instruments
PXIe-4464. The NI PXIe-4464 is available in two input connector variants: BNC and mXLR.
The calibration procedure is common between them; only the connecting cabling is different. In
this document, the BNC and mXLR variants are referred to inclusively as the NI PXIe-4464. For

Software
Calibrating the NI PXIe-4464 requires the installation of NI-DAQmx on the calibration system.
NI-DAQmx 14.1 added driver support for the NI PXIe-4464. For the list of devices supported
by a specific release, refer to the NI-DAQmx Readme, available on the version-specific
download page or installation media.
You can download NI-DAQmx from
. NI-DAQmx supports LabVIEW,

LabWindows
/CVI
, C/C++, C#, and Visual Basic .NET. When you install NI-DAQmx, you
only need to install support for the application software that you intend to use.

Page 5: Test Conditions
The following setup and environmental conditions are required to ensure the NI PXIe-4464 meets published specifications. • Keep connections to the NI PXIe-4464 as short as possible. Long cables and wires act as antennas, picking up extra noise that can affect measurements. •... -
Page 6: Verification
Analog Input Performance Verification This section verifies the analog input (AI) performance of the NI PXIe-4464. Some, but not all, performance characteristics are affected by adjustment and are subject to reverification after adjustment. Characteristics affected by adjustment have As Left test limits in addition to As Found test limits. - Page 7 -10, 0, 10, 20, and 30 as required.

Page 16: Adjustment
Adjustment If the NI PXIe-4464 successfully passed each of the verification procedures within the As Left test limits without adjustment, then an adjustment is recommended, but not required, to warrant the published specifications for the next calibration interval. If the device was not within the As Left test limits, you can perform the adjustment procedure to improve the device accuracy and reset the calibration interval. - Page 17 ) signal, no offset, at a frequency of 90.000 kHz. 17.
