NI PXIe-4463 Calibration Procedure

Initial Setup

Refer to the

NI PXIe-4463 Getting Started Guide

for information about how to install the

software and hardware and how to configure the device in NI Measurement & Automation
Explorer (MAX).

Note

When a device is configured in MAX, it is assigned a device name. Each

function call uses this device name to determine which device to calibrate. This
document uses

Dev_name

to refer to the device name. In the following procedures,

use the device name as it appears in MAX.

Note

If the NI PXIe-4464 is used for the AO noise verification, install it in the

rightmost PXI Express slot.

Self-Calibration

The NI PXIe-4463 includes precise internal circuits and calibration references used during
self-calibration to adjust for drift over time and temperature.

Note

No signal connections are needed for self-calibration.

Complete the following steps to self-calibrate the device.
1.

Wait 15 minutes for the device to warm up.

2.

Launch MAX.

3.

Select

My System»Devices and Interfaces

, and then select the NI PXIe-4463 device to

self calibrate.

4.

Click

Self-Calibrate

in the upper right corner of the window.

Verification

The following procedures describe the sequence of operation and provide test points required to
verify the NI PXIe-4463. The verification procedures assume that adequate traceable
uncertainties are available for the calibration references.

Note

The verification procedure requires performing a self-calibration as a first

step unless it is done immediately after an adjustment. Refer to the

Self-Calibration

section for instructions on performing a self-calibration.

Characteristics have As Found limits for verification

before adjustment

and As Left limits for

reverification

after adjustment

. Characteristics unaffected by adjustment have test limits with no

additional qualification.

Note

If any test fails verification or reverification, confirm that you have met the

Test Conditions

before returning your device to NI. Refer to

Worldwide Support and

for assistance in returning the device to NI.
