PicoScope 3000 Series

Spectrum analyzer

The spectrum view plots amplitude against frequency and is ideal for finding noise, crosstalk or distortion in signals. PicoScope uses a fast Fourier transform (FFT) spectrum

analyzer, 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 of up to 200 MHz. A comprehensive range of settings gives you control

over the number of spectrum bins, window functions, scaling (including log/log) and display mode (instantaneous, average or peak-hold).

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. You can apply mask limit testing to a spectrum and can even use the AWG and spectrum mode together to perform swept

scalar network analysis.
