No, SW4 selects the power source for the PPK and DUT both. It could not be cut off for DUT.

Hi Amanda,

Thanks for your help.

My intention is not to power my DUT from SW4. I would just like to measure current without sourcing anything.

My DUT is self-powered and doesn't require an external power source. I would like to use the power profiler kit to just measure the current on a section of my device. Is there a way I can do this?

Best,

Adonis

Hi,

Do you switch to the External power (External) on Power select (SW4)?

External: An external power supply is the power source connected to the External DUT supply(P22) connector of the PPK.

You can also take a look at this blog post, which shows how to measure an external DUT.

Best regards,

Amanda
