Equipment and Other Test Requirements
This section describes the test equipment, software, documentation, and
test conditions required for calibrating the SCXI-1120/D modules.
Test Equipment
Calibration requires a high-precision voltage source with at least 50 ppm
accuracy and a multiranging 5 1/2 digit digital multimeter (DMM) with
15 ppm accuracy.
Instruments
NI recommends the following instruments for calibrating SCXI-1120/D
modules:
•
Calibrator—Fluke 5700A
•
DMM—NI 4060 or HP 34401A
If these instruments are not available, use the accuracy requirements listed
previously to select substitute calibration instruments.
Connectors
If you do not have custom connection hardware, you need the following
connectors:
•
Terminal block, such as the SCXI-1320
•
Shielded 68-pin connector cable
•
50-pin ribbon cable
•
50-pin breakout box
•
SCXI-1349 adapter
These components give easy access to the individual pins on the
SCXI-1120/D module front and rear connectors.
Software and Documentation
No special software or documentation is necessary to calibrate the
SCXI-1120/D module. This calibration document contains all the
information you need to complete the verification and adjustment
procedures. If you would like more information on the module, refer
