Now turn off storage mode and turn on FFT mode to look at the frequency spectrum, try the settings

shown here. Moving the variable resistor knob will change the spectrum shown.

You can also use storage mode when in FFT mode, so turn it on now.

In this way you can show the peak

energy achieved at each frequen-

cy. But this is only useful on a sta-

ble waveform, so if you move the

variable resistor knob now the sig-

nal will fill the screen as the peaks

move across the display.

Most oscilloscopes and spectrum analyzers have a storage mode like this of some form.
