SUMMARY

The discussion centers on obtaining a V-I curve using an Agilent oscilloscope. Users reported issues with flat line outputs when connecting voltage (V) and current (I) signals via BNC cables. The solution involves setting the oscilloscope to XY mode, which allows for the proper display of V against I. Specific instructions for various Agilent models are available through the provided link.

PREREQUISITES
  • Understanding of Agilent oscilloscope models and their functionalities
  • Familiarity with BNC cable connections for voltage and current measurements
  • Knowledge of XY mode operation on oscilloscopes
  • Basic principles of V-I curve analysis in electrical engineering
NEXT STEPS
  • Research how to set up XY mode on different Agilent oscilloscope models
  • Explore troubleshooting techniques for oscilloscope signal display issues
  • Learn about the significance of V-I curves in circuit analysis
  • Investigate advanced features of Agilent oscilloscopes for enhanced measurements
USEFUL FOR

Electrical engineers, technicians working with oscilloscopes, and students studying circuit analysis will benefit from this discussion.

Ok, we have a standard Agilent oscilloscope and need to get a V-I curve for this bad boy. We got a BNC cable with our V and another with our I, but we can't get a V-I curve at all. We just get 2 flat lines that correspond to V and I independantly.

Our instructions say we just plug V into the X end of the 'scope and the I into the Y. Is there a menu somewhere to set this thing or what?

You need to set the 'scope to XY mode. Here are instructions for several Agilent models:
