This is a LabVIEW Project which uses Keysight's DSOX2014 oscilloscope to perform automated frequency response measurements. It was developed for an assignment in uni, where the task was to measure and study frequency responses of LDR and photodiode optical sensors.
Unfortunately, I have lost the latest version of this project which included saving the measurements to a report. Nevertheless, this version does perform oscilloscope configuration, wavegen configuration, and swept measurements and could be easily extended.
This project is using VIs from [InfiniiVision X-Series Oscilloscope LabVIEW Instrument Drivers] to communicate with the scope.
Code is split in 3 parts:
- Sweep VIs
- Waveform generator VIs
- Main VIs
Sweep VIs contain SubVIs used to generate linspace and logspace arrays. VIs located in Waveform generator VIs are used to configure
and control oscilloscope's waveform generator. Square wave response measurements.vi is the "main" VI in this project.
