SCXI-1121 Calibration Procedure
This section describes the test equipment, software, documentation, and
test conditions required for calibrating the SCXI-1121 module.
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 120 and 800 Ω ±10% precision resistors.
Instruments
NI recommends the following instruments for calibrating the SCXI-1121
module:
• 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-1121 front and rear connectors.
You do not need any special software or documentation to calibrate the
SCXI-1121 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 to the SCXI-1121 User
Manual.
