Equipment and Other Test Requirements

This section describes the equipment, software, documentation, and test

conditions required for calibrating the SCXI-1125.

Calibration requires a high-precision voltage source with at least 50 ppm

accuracy, a multiranging 5 1/2 digit digital multimeter (DMM) with

15 ppm accuracy,and a NationalI nstrumentsE Series DAQ device.

National Instruments recommends the following instruments for

calibrating the SCXI-1125:

• Calibrator—Fluke 5700A

• DMM—NI 4060 or HP 34401A

• National Instruments E Series DAQdevice

Ifthese instruments are not available, use the accuracy requirements listed

aboveto select a substitute calibration standard.

Note If you do not havecustom connection hardware, you will need a connector block

suchas the National Instruments SCXI-1320, a shielded 68-pin connector cable, a 50-pin

ribbon cable, a 50-pin breakout box, and an SCXI adapter.These components give easy

accessto the individual pins on the SCXI-1125 front and rear connectors.

You will need the following software and documentation to calibrate

the SCXI-1125 signal conditioning modules. You can find these on the

National Instruments Web site at ni.com/calibration:

• The latest versionof the National Instruments NI-DAQdriver

•NI-DAQ Function Reference Online Help file

• NI-DAQ User Manual for PC Compatibles

The SCXI-1125 calibration procedure requires the latest version of the

NationalInstruments NI-DAQ driver on the calib ration system. The driver

supports a number of programming languages, including LabVIEW,

LabWindows/CVI, Microsoft Visual C++, Microsoft Visual Basic, and

BorlandC++. When you install the driver,you only need to install supp ort

for the programming language you will use.
