Programming GPIB Instruments in Labview: Need Help!

Click For Summary
SUMMARY

This discussion focuses on programming GPIB instruments, specifically a voltmeter and oscilloscope, using LabVIEW. The user has successfully set up the necessary drivers but struggles to find clear documentation for programming these instruments. They are particularly interested in converting data strings from the voltmeter into numerical values for plotting on a waveform graph. The user has attempted various string conversion tools within LabVIEW's string functions without success.

PREREQUISITES
  • Familiarity with LabVIEW programming environment
  • Understanding of GPIB (General Purpose Interface Bus) communication
  • Knowledge of data types and string manipulation in LabVIEW
  • Experience with waveform graph plotting in LabVIEW
NEXT STEPS
  • Research LabVIEW string conversion functions for numerical data
  • Explore GPIB instrument programming examples in LabVIEW
  • Learn about waveform graph configuration in LabVIEW
  • Visit specialized GPIB forums for community support and resources
USEFUL FOR

LabVIEW developers, engineers working with GPIB instruments, and anyone seeking to visualize data from voltmeters and oscilloscopes in LabVIEW.

Hello all,
I am trying to program a GPIB instrument (voltmeter and oscilloscope) in labview. I already have all the drivers set up, but I am having trouble finding easy to understand documentation on how to program these instruments. Does you know of any?

Right now I am stuck on trying to plot data read from the voltage meter onto a waveform graph. Apparently the voltmeter outputs data strings, how do I convert this to numbers? I have already tried multiple conversion tools under the string functions.

Any help or guidelines would be appreciated.
Thank you!
