The Picoscope 4424 and 4224 offer both a high resolution (12 bits) and a high DC accuracy (1%) making them an excellent choice for noise, vibration, precision electronics and mechanical analysis.

The optional IEPE interface (see below) allows for the direct connection and powering of industry standard accelerometers and microphones.

High resolution offers 16x more detail

The PicoScope 4224 and 4424 are 12-bit oscilloscopes that offer 16 times more vertical resolution than traditional 8-bit oscilloscopes (4096 vertical levels vs 256). The example shows how with a 12-bit oscilloscope (blue trace) you can zoom in to reveal details of the signal that are not visible on an 8-bit oscilloscope (black trace).

As well as the high vertical resolution, the 32 million sample buffer memory ensures a high horizontal resolution as well. You can collect long detailed captures without the sampling rate dropping.

Once you have seen high-resolution waveforms on a high-resolution PC monitor you will never want to use a traditional benchtop oscilloscope with its small display again.

As well as improved oscilloscope traces, high resolution offers big benefits when performing spectrum analysis offering an additional 20 dB dynamic range on the spectrum over 8-bit oscilloscopes. Signals that were previously hidden in the noise floor are now clearly visible and the spectrum becomes a powerful tool to track down the causes of noise.

IEPE Interface

The PicoScope 4224 is available with an optional internal IEPE (integrated circuit piezoelectric) interface allowing for the direct connection and powering of industry standard accelerometers and microphones.

When disabled the channels can be used as normal oscilloscope inputs. When IEPE is enabled (each channel has independent control via software) the input is AC coupled and a 24 V, 4 mA signal is output to power external sensors.

The high resolution and dynamic range of the 4224 makes it ideal for use with accelerometers and microphones. Having the IEPE interface built in makes for a compact, portable solution.

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 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 for automated testing.

Picoscope 4424

Signal integrity

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

Careful front-end design and shielding reduces noise, crosstalk and harmonic distortion. Years of oscilloscope design experience can be seen in improved bandwidth flatness and low distortion.

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

Portability

Pico Technology oscilloscopes are small, light and portable. In the lab they take up the minimum of bench space while for the engineer on the move they are small enough to fit in a bag with your laptop.

The USB connection makes printing, copying, saving, and emailing your data from the field quick and easy. The high-speed USB interface allows fast data transfer, while USB powering removes the need to carry around a bulky external power supply, making the scope even more portable for the engineer on the move.

The PicoScope 4424, 4224 and 4224 IEPE are supplied with software, documentation and USB cable. For the 4224 and 4424 a kit also containing oscilloscope probes and a carry case is available.

PicoScope 4224 & 4424 Features

Advanced digital triggering

The majority of digital oscilloscopes still use an analog trigger architecture based on comparators. This causes time and amplitude errors that cannot always be calibrated out and often limits the trigger sensitivity at high bandwidths.

Over 20 years ago Pico first pioneered the use of fully digital triggering using the actual digitized data. This technique reduces trigger errors and allows our oscilloscopes to trigger on the smallest signals, even at the full bandwidth. Trigger levels and hysteresis can be set with high precision and resolution.

The PicoScope 4224 and 4424 offer industry-leading set of advanced triggers including pulse width, runt pulse, windowed, logic and dropout.

Waveform buffer and navigator

Ever spotted a glitch on a waveform, but by the time you’ve stopped the scope it has gone? With PicoScope you no longer need to worry about missing glitches or other transient events. PicoScope can store the last ten thousand oscilloscope or spectrum waveforms in its circular waveform buffer.

The buffer navigator provides an efficient way of navigating and searching through waveforms, effectively letting you turn back time. Tools such as mask limit testing can also be used to scan through each waveform in the buffer looking for mask violations.

Digital persistence modes

Advanced display modes allow you to collect thousands of waveforms per second. New or more frequent data can be displayed in a brighter color or shade. This makes it easy to see glitches and dropouts and to estimate their relative frequency. Choose between analog persistence, digital color, fast or custom display modes.

More information on Persistence modes >>

The waveform buffer navigator can quickly highlight waveforms that fail the mask limit test

Mask limit testing

Mask limit testing allows you to compare live signals against known good signals, and is designed for production and debugging environments. Simply capture a known good signal, draw a mask around it, and then attach the system under test. PicoScope will check for mask violations and perform pass/fail testing, capture intermittent glitches, and can show a failure count and other statistics in the Measurements window.

More information on Mask limit testing >>

Serial bus decoding and protocol analysis

PicoScope can decode 1-Wire, ARINC 429, CAN & CAN-FD, DCC, DMX512, Ethernet 10Base-T and 100Base-TX, FlexRay, I²C, I²S, LIN, PS/2, MODBUS, SENT, SPI, UART (RS-232 / RS-422 / RS-485), and USB 1.1 protocol data as standard, with more protocols in development and available in the future with free-of-charge software upgrades.

Graph format shows the decoded data (in hex, binary, decimal or ASCII) in a data bus timing format, beneath the waveform on a common time axis, with error frames marked in red. These frames can be zoomed to investigate noise or signal integrity issues.

Table format shows a list of the decoded frames, including the data and all flags and identifiers. You can set up filtering conditions to display only the frames you are interested in or search for frames with specified properties. The statistics option reveals more detail about the physical layer such as frame times and voltage levels. PicoScope can also import a spreadsheet to decode the data into user-defined text strings.

High-end features as standard

Buying a PicoScope is not like making a purchase from other oscilloscope companies, where optional extras considerably increase the price. With our scopes, high-end features such as serial decoding, mask limit testing, advanced math channels and segmented memory are all included in the price.

To protect your investment, both the PC software and firmware inside the scope can be updated. Pico Technology have a long history of providing new features for free through software downloads. We deliver on our promises of future enhancements year after year, unlike many other companies in the field. Users of our products reward us by becoming lifelong customers and frequently recommending us to their colleagues.
