The objective of this project is to develop an automatic software to evaluate the calibration status of an oscilloscope, via IEEE 488.2 interface, relaying on LabVIEW, on NI GPib-USB controller, on the scope "measure" functions and on a Fluke5500a calibrator.
The software could be used to set an automatic testing station for oscilloscopes. The developed program sets an automatic measure process, and verifies every oscilloscope "measure" function, calculating error and standard deviation from the reference value set with the calibrator. The data obtained and its relative calibrator uncertainty is stored in a spreadsheet file, for easy elaboration and consultation. In addition it is possible to visualize the average error with the relative calibrator uncertainty in graphical form. Evaluating the data, the user can apply the needed correction for every measure and make the needed calibration adjustment to the device.
