CALIBRATION PROCEDURE
SCXI -1520
This document contains information and step-by-step instructions for
calibrating the National Instruments SCXI-1520 module.
Equipment and Other Test Requirements
This section describes the equipment, software, documentation, and test
conditions required for calibrating the SCXI-1520.
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 16-bit data acquisition (DAQ) device.
NI recommends the following instruments for calibrating the SCXI-1520.
•
Calibrator—Fluke 5700A
•
DMM—NI 4060 or Agilent 34401A
•
16-bit 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 need an SCXI-1314 terminal
block and a shielded 68-pin connector cable. These components give easy access to the
individual pins on the SCXI-1520 front connectors. You also need an SCXI-1349 cable
adapter to connect the SCXI-1520 to the DAQ device.
Software and Documentation
Use the following software and documentation to calibrate the SCXI-1520.
