Re: Measuring how dirty the power is

I have a RF device I am trying to build which is failing to run when running
off wall wart power. It will run if I change the power to battery so I feel
like its due to dirty power. How would I go about testing this with a
meter?

Poor planning on your part does not constitute an emergency on my part.

Other than measuring the voltage and seeing if it varies when you try
to run you device there is not much you can do with a meter. The most
likely cause is that the PS is not capable of supplying the current
required. It is unlikely that the power is "dirty". To see "dirty"
power you would need an oscilloscope.
