PicoScope® 6000E Series

FFT spectrum analyzer

The spectrum view plots amplitude against frequency and is ideal for finding noise,

crosstalk or distortion in signals. The spectrum analyzer in PicoScope is of the Fast

Fourier Transform (FFT) type which, unlike a traditional swept spectrum analyzer, can

display the spectrum of a single, non-repeating waveform. With up to a million points,

PicoScope’s FFT has excellent frequency resolution and a low noise floor.

With a click of a button, you can display a spectrum plot of the active channels, with a

maximum frequency up to the bandwidth of your scope. A full range of settings gives

you control over the number of spectrum bands (FFT bins), scaling (including log/

log) and display modes (instantaneous, average, or peak-hold). A selection of window

functions allow you to optimize for selectivity, accuracy or dynamic range.

You can display multiple spectrum views alongside oscilloscope views of the same

data. A comprehensive set of automatic frequency-domain measurements can be added

to the display, including THD, THD+N, SNR, SINAD and IMD. A mask limit test can be

applied to a spectrum and you can even use the AWG and spectrum mode together to

perform swept scalar network analysis.
