Testing Noisy Power Supply Outputs

Join Teledyne LeCroy for this 30-minute Oscilloscope Coffee Break Series to remind us how to get the most test and debug capability from our oscilloscopes. Grab your refreshment and spend a few minutes with us as we focus on a specific topic each month.

We didn’t expect to have DC outputs be so noisy! Is it really the circuit that is a problem or is our scope and/or probe causing signal integrity issues? We even tried changing output capacitors to improve the performance, but why are we seeing 2X greater output noise than we expected?

In this session we review which probes are best for your application and how best to connect to your oscilloscope to minimize RF pick up.

Topics to be included:

  • Scope setups, which is best?
    • 1 MΩ or 50Ω?
    • AC or DC Coupling?
    • Bandwidth limits?
  • Probing output power
    • What is the appropriate probe to use?
    • Challenges with DC-DC low impedance sources
    • Accessories – how do we reduce probe effects on our measurements?

Presenter: Stephen Murphy, Teledyne LeCroy Applications Engineer
