I have a question about using the FFT function on the TDS3054B Digital Phosphor Oscilloscope. When I am using the FFT in Linear mode, it autosets the horizontal scale constantly and makes getting a good reading impossible. Is there a way to disable this feature? I searched high and low through the menus and also in the user guide (which does not even mention the FFT). I really need this to work so that we can move forward with EMI testing. Any help would be greatly appreciated.
Love the scope BTW, everything works great.
