200 MHz USB 3.0 oscilloscopes with 16 channel logic analyzer

PicoScope 3000 Series USB-powered PC oscilloscopes are small, light, and portable and can easily slip into a laptop bag while offering a range of high-performance specifications.

These oscilloscopes offer 2 or 4 analog channels and a built-in function / arbitrary waveform generator. MSO models add 16 digital channels.

Supported by the advanced PicoScope 6 software, these devices offer an ideal, cost-effective package for many applications, including embedded systems design, research, test, education, service, and repair.


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.

In 1991 Pico 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 reduced rearm delay provided by digital triggering, together with segmented memory, allows the capture of a new waveform every microsecond until the buffer is full.

The PicoScope 3000 series offers an industry-leading set of advanced triggers including pulse width, windowed and dropout.  In addition logic triggering allows you to trigger the scope when any or all of the 16 digital inputs match a user-defined pattern.

Hardware Acceleration Engine (HAL3)

fast oscilloscope waveform update rateSome oscilloscopes struggle when you enable deep memory; the screen update rate slows and controls become unresponsive. PicoScope 3000 series avoids this limitation with use of a dedicated hardware acceleration engine inside the oscilloscope.  Its massively parallel design effectively creates the waveform image to be displayed on the PC screen and allows the continuous capture and display to the screen of over 440 million samples every second.  PicoScope oscilloscopes manage deep memory better than competing oscilloscopes, both PC-based and bench-top.

The PicoScope 3000 series is fitted with third-generation hardware acceleration (HAL3). This speeds up areas of oscilloscope operation such as allowing waveform update rates in excess of 100,000 waveforms per second and the segmented memory / rapid trigger modes. The hardware acceleration engine ensures that any concerns about the USB connection or PC processor performance being a bottleneck are eliminated. Hardware acceleration ensures fast screen update rates even when collecting 10,000,000 samples per wavefor

100,000 waveforms per second

oscilloscope persistence mode

Persistence mode rapidly superimposes multiple waveforms on the same view, with more frequent or newer waveforms drawn in brighter colors than older ones. This emulates the phosphor display of a conventional analog scope and is useful for displaying and interpreting complex analog signals such as video waveforms and analog modulation signals.

More information on color persistence modes >>

Hardware acceleration (HAL3) allows waveform update rates of up to 100,000 per second in Fast persistence mode – allowing you to collect thousands of waveforms per second in order to quickly spot glitches and observe jitter.

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.

Mask limit testing

Mask limit testing - good waveform

Waveform mask limit test – Pass

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.


PicoScope can be programmed to take an action when certain conditions are met PicoScope can be programmed to execute actions when certain events occur.

The events that can trigger an alarm include mask limit fails, trigger events and buffers full.

The actions that PicoScope can execute include saving a file, playing a sound, executing a program or triggering the signal generator / AWG.

Alarms, coupled with mask limit testing help create a powerful and time saving waveform monitoring tool.  Capture a known good signal, auto generate a mask around it and then use the alarms to automatically save any waveform (complete with a time/date stamp) that does not meet specification.

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, segmented memory, and a signal generator 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.

BNC terminators and leads

All our BNC terminators, attenuators, leads and adaptors 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.


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