Re: DC voltage on a DC coupled spectrum analyzer


Disregard my post above as it has become obvious to me from Ed's post about exceeding the lower limits of the spectrum analyzer that source impedance is important when running low frequencies especially DC which I want to avoid anyways

I must add at one time I used the output of an iPhone and an iPad turned down low generating a sine wave before, it worked but now it has me thinking was that a bad idea?

Thanks for the excellent replies
