12 bit oscilloscopes with optional IEPE interface

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.

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).

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.


Advanced digital triggers

Oscilloscope digital triggers

 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

waveform buffer
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 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.More information on Waveform buffer >>

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 >>

Mask limit testing

Mask limit testing - good waveform

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.

Serial bus decoding and protocol analysis

CANBus analysis in PicoScope PicoScope can decode 1-Wire, ARINC 429, CAN, DCC, DMX512, Ethernet 10Base-T and 100Base-TX,  FlexRay, I²C, I²S, LIN, PS/2, SENT, SPI, UART (RS-232 / RS-422 / RS-485), and USB protocol data as standard, with more protocols in development, and available in the future with free-of-charge software upgrades.In 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.In 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.More information on Serial bus decoding and protocol analysis – overview >>

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.


Passive oscilloscope probes

Our ergonomically designed passive oscilloscope probes are suitable for use with all major brands of oscilloscopes as well as the PicoScope range of USB Oscilloscopes. Passive probes don’t require a power supply or batteries so are lightweight and easily portable.

Active oscilloscope probes

This range includes high-voltage probes that extend the input range of your scope, and high-frequency probes that boost its input impedance for more accurate measurements.

All active probes require a power supply or batteries. Our battery-powered probes are supplied complete with batteries, while optional AC adaptors are available for the externally powered types.

Current probes (clamps)

Clamp-on current probes or “current clamps” enable you to measure currents without breaking the electrical circuit. Current clamps are designed with jaws that can be opened, placed around the conductor and clamped shut to form a magnetic loop around the conductor.

Current clamps offer a safe, cost-effective, simple and accurate way to take current measurements.

Our range of current clamps can be used with Pico Oscilloscopes and Pico Data Loggers, as well all major brands of oscilloscopes and multimeters.


We supply single-axis and three-axis accelerometers that connect to an oscilloscope for measuring noise and vibration.

BNC terminators and leads

All our BNC terminators, attenuators, leads and adapters are compatible with 50 Ω BNC connectors.

Clips, leads and 4 mm probes

From gator/croc clips to acupuncture probes, here you will find a variety of popular accessories for use with test and measurement equipment.

Our test clips are suitable for general-purpose test and measurement as well for automotive diagnostics applications. The test clips are designed for use with our range of test leads.
