PicoScope 6000 — The Highest Performance USB Scopes

Highest Performance USB Oscilloscopes

The fastest sampling, highest bandwidth and deepest memory of any USB oscilloscope on the market today.
  • 4 channels.
  • 500 MHz bandwidth.
  • 5 GS/s real–time sampling.
  • 2 GS memory!
  • Arbitrary waveform generator.
  • Serial decoding.
  • Mask limit testing.
  • USB 3.0 interface.


Over two decades of oscilloscope design experience has resulted in the PicoScope 6000 Series — the ultimate in USB oscilloscope design.

High bandwidth,high sampling rate

With 250 MHz to 500 MHz analog bandwidths complemented by a real-time sampling rate of 5 GS/s, the PicoScope 6000 Series scopes can display single-shot pulses with 200 ps time resolution. Equivalent time sampling (ETS) mode boosts the maximum sampling rate to 50 GS/s, giving an even finer timing resolution of 20 ps for repetitive signals.

Huge buffer memory

The PicoScope 6000 Series gives you the deepest buffer memory available as standard on any oscilloscope at any price. The SuperSpeed USB 3.0 interface and hardware acceleration ensures that the display is smooth and responsive even with long captures. Other oscilloscopes have high maximum sampling rates, but without deep memory they cannot sustain these rates on long timebases. The 2-gigasample buffer on the PicoScope 6404D can hold two 200 ms captures at the maximum sampling rate of 5GS/s. To help manage all this data, PicoScope can zoom up to 100 million times using a choice of two zoom methods. There are zoom buttons as well as an overview window that lets you zoom and reposition the display by simply dragging with the mouse
Huge buffer memory

Store up to 10,000 waveforms in the buffer

Store up to 10,000 waveforms in the 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.

With PicoScope you can divide the buffer memory into as many as 10,000 individually triggered segments.  If you manage to completely fill the waveform buffer PicoScope will use the first in, first out principle to ensure that the buffer always contains the latest waveforms.

Use the visual buffer navigator to scan through the segments, or use the mask limit tools to scan through, highlighting any that fail.

Arbitrary waveform and function generator

Arbitrary waveform and function generator

Every model includes a built-in DC to 20 MHz function generator with sine, square, triangle and DC waveforms. D models add a built-in 12-bit, 200 MS/s arbitrary waveform generator with a 64,000 sample buffer memory. You can import arbitrary waveforms from data files, oscilloscope waveforms or create and modify them using the built-in graphical AWG editor.



Over two decades of PC–based design experience and listening to your needs and desires has resulted in the PicoScope 6000 Series — the ultimate in USB oscilloscope design.

Analog and digital low-pass filtering

Analog and digital low-pass filtering

Each input channel has its own digital low-pass filter with independently adjustable cut-off frequency from 1 Hz to the full scope bandwidth. This enables you to reject noise on selected channels while viewing high-bandwidth signals on the others. An additional selectable analog bandwidth limiter on each input channel can be used to reject high frequencies that would otherwise cause aliasing.

Digital triggering

Most digital oscilloscopes sold today still use an analog trigger architecture based on comparators. This can cause time and amplitude errors that cannot always be calibrated out. The use of comparators 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.

Digital triggering also reduces re-arm delay and this, combined with the segmented memory, allows the triggering and capture of events that happen in rapid sequence. At the fastest timebase you can use rapid triggering to collect 10,000 waveforms in under 10 milliseconds.Advanced triggers The mask limit testing function can then scan through these waveforms to highlight any failed waveforms for viewing in the waveform buffer.

Advanced triggers

As well as the standard range of triggers found on most oscilloscopes, the PicoScope 6000 Series has a built-in set of advanced triggers to help you capture the data you need. All triggering is digital, resulting in high threshold resolution with programmable hysteresis and optimal waveform stability.

High signal integrity

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. Years of oscilloscope experience leads to improved pulse response and bandwidth flatness. The result is simple: when you probe a circuit, you can trust in the waveform you see on the screen.

Hardware acceleration

On some oscilloscopes, enabling deep memory has a penalty: the screen update rate slows down and the controls become unresponsive as the processor struggles to cope with the amount of data. Thanks to the hardware acceleration inside PicoScope deep-memory oscilloscopes, you can collect waveforms containing hundreds of millions of samples while keeping fast screen update rates and a responsive user interface.

Hardware accelerationHardware acceleration ensures fast screen
update rates even when collecting
100,000,000 samples per waveform

Dedicated hardware inside the oscilloscope processes multiple streams of data in parallel to construct the waveform that will be displayed on the screen. This is done far faster than any PC processor could manage, and together with USB 3.0 SuperSpeed data transfer eliminates any bottlenecks between the oscilloscope and the PC.


For example, the scope may be set to capture 100,000,000 samples but the PicoScope display window may be only 1000 pixels wide. In this case, the scope intelligently compresses the data into 1000 blocks of 100 000 samples each. Unlike simple decimation, which throws away most of the data, PicoScope hardware acceleration guarantees that you see any high-frequency details such as narrow glitches, even when the display is zoomed out.

aggregationBoth waveforms show the same signal using different types of hardware acceleration.
Top waveform: using PicoScope hardware acceleration.
Bottom waveform: simulates the decimation used by many oscilloscopes — signal data is lost.
