Most digital oscilloscopes have been designed for viewing fast digital signals. The trend has been to use new technology solely to increase sampling rate and bandwidth. With the PicoScope 4262, however, we have focused on whata s important for measuring analog signals: increasing the resolution, improving dynamic range, and reducing noise and distortion.

The result is an oscilloscope / FFT analyzer that has a level of performance to put most audio analyzers to shame yet has a 5 MHz bandwidth making it equally suitable for vibration and ultrasound signals as well as a wide range of precision measurement tasks.

Many applications such as vibration analysis require long captures at high sampling rates, which requires a deep capture memory. The PicoScope 4262 has a 16 million sample buffer memory so can capture at 10 MS/s for timebases as long as 100 ms/div. If you require longer times, the USB streaming mode can sample directly into PC memory.

FFT spectrum analyzer
The spectrum view plots amplitude vs 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.

A full range of settings gives you control over the number of spectrum bands (FFT bins), window types, scaling (including log/log) and display modes (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. 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.

Arbitrary waveform and function generator

The PicoScope 4262 has a built-in 20 kHz function generator (sine, square, triangle, DC voltage, ramp, sinc, Gaussian, halfa sine, white noise and PRBS). The function generator offers an outstanding sine wave distortion performance of 102 dB SFDR.
