I stated it pretty much how the client stated it...so thats why I was curious to see if it would get a response. Could there be harmonics on the output? As far as harmonics on the input, thats not a factor of the supply but the source. >From: Douglas Butler >Reply-To: pic microcontroller discussion list >To: PICLIST@MITVMA.MIT.EDU >Subject: Re: [EE]: Power supply questions: load factor & Harmonic > measurements >Date: Thu, 21 Mar 2002 12:14:29 -0500 > >Are you sure you want the harmonic measurement at the OUTPUT?
