PicoScope 2000 Series oscilloscopes

Persistence mode

PicoScope 6 persistence mode options allow you to see old and new data

superimposed, with newer waveforms drawn in a brighter color or deeper shade. This

makes it easy to spot glitches and dropouts and estimate their relative frequency –

useful for displaying and interpreting complex analog signals such as video waveforms

and analog modulation signals.

The PicoScope 2000 Series’ hardware acceleration means that, in Fast Persistence

mode, waveform update rates of up to 80 000 waveforms per second are achievable.

Color-coding or intensity-grading shows which areas are stable and which are

intermittent. Choose between analog intensity, digital color and fast display modes or

create your own custom setup.

Spectrum analyzer

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

crosstalk or distortion in signals. PicoScope 6 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 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).

Display multiple spectrum views with different channel selections and zoom factors,

and place these alongside time-domain views of the same data. Choose from

a number of automatic frequency-domain measurements to add 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.
