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 what’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.

Advanced display

PicoScope software dedicates almost all of the display area to the waveform. This ensures that the maximum amount of data is seen at once. The viewing area is much bigger and of a higher resolution than with a traditional benchtop scope.

With a large display area available, you can also create a customizable split-screen display, and view multiple channels or different views of the same signal at the same time. As the example shows, the software can even show multiple oscilloscope and spectrum analyzer traces at once. Additionally, each waveform shown works with individual zoom, pan, and filter settings for ultimate flexibility.

The PicoScope software can be controlled by mouse, touchscreen or keyboard shortcuts.

FFT spectrum analyzer

The spectrum view plots amplitude against frequency, revealing details that would otherwise be hidden in an oscilloscope view. It is ideal for finding noise, crosstalk or distortion in signals. The spectrum analyzer in PicoScope is of the Fast Fourier Transform (FFT) type that, 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. To focus on a specific frequency range, you can directly set the start and stop values of the analyzer frequency axis. A full range of settings gives you control over the number of spectrum bands (FFT bins), start/stop frequencies, scaling (including log/log) and display modes (instantaneous, average, or peak-hold). A selection of window functions allows 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. You can even use the AWG and spectrum mode together to perform swept scalar network analysis.

The spectrum works with the waveform buffer so you can capture and rewind through thousands of spectrum plots or why not use the mask limit tests to scan through them all automatically? Spectrum masks can also work with PicoScope actions so you can leave the spectrum running continuously and choose to save mask fails to disk or even sound an alarm.

Arbitrary waveform and function generator

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

As well as basic controls to set level, offset and frequency, more advanced controls allow you to sweep over a range of frequencies. Combined with the spectrum peak hold option this makes a powerful tool for testing amplifier and filter responses.

Trigger tools allow one or more cycles of a waveform to be output when various conditions are met such as the scope triggering or a mask limit test failing.

As well as the standard waveforms available from the function generator, custom waveforms can be created using the 16 bit / 192 kS/s arbitrary waveform generator (AWG). AWG waveforms can be created or edited using the built-in editor, imported from oscilloscope traces, or loaded from a spreadsheet.

High signal integrity

Most oscilloscopes are built down to a price. Ours are built up to a specification.

Careful front-end design and shielding reduces noise, crosstalk and harmonic distortion. Over 20 years of high resolution oscilloscope design experience leads to improved pulse response and bandwidth flatness.

We are proud of the dynamic performance of our products and publish these specifications in detail. The result is simple: when you probe a circuit, you can trust in the waveform you see on the screen.

Portability

The PicoScope 4262 oscilloscope is small, light and portable and requires no external power supply.  

In the lab they take up the minimum of bench space while for the engineer on the move they slip neatly into a laptop bag.
