Equipment and Other Test Requirements
This section describes the equipment, software, documentation, and test
conditions required for calibrating the SCXI-1104.
Test Equipment
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 National Instruments E Series DAQ device.
National Instruments recommends the following instruments for
calibration of an SCXI-1104:
•
Calibrator—Fluke 5700A
•
DMM—NI 4060 or HP 34401A
•
National Instruments E Series DAQ device
If these instruments are not available, use the accuracy requirements listed
above to select a substitute calibration standard.
Note
If you do not have custom connection hardware, you will need a connector block
such as the National Instruments SCXI-1300, a shielded 68-pin connector cable, a 50-pin
ribbon cable, a 50-pin breakout box, and an SCXI adapter. These components give easy
access to the individual pins on the SCXI-1104 front and rear connectors.
Software and Documentation
You will need the following software and documentation to calibrate the
SCXI-1104. You can find these on the National Instruments Web site at

Software
The SCXI-1104 calibration procedure requires the latest version of the
National Instruments NI-DAQ driver on the calibration system. The driver
supports a number of programming languages, including LabVIEW,
LabWindows/CVI, Microsoft Visual C++, Microsoft Visual Basic, and
Borland C++. When you install the driver, you only need to install support
for the programming language you will use.
