PicoScope 4262 Features
Hardware acceleration ensures fast screen
update rates even when collecting
10,000,000 samples per waveform
Hardware Acceleration Engine (HAL2)
Some oscilloscopes struggle when you enable deep memory; the screen update rate slows and controls become unresponsive. PicoScope 4262 avoids this limitation with use of a dedicated hardware acceleration engine inside the oscilloscope. Its 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 millions of samples every second. PicoScope oscilloscopes manage deep memory better than competing oscilloscopes, both PC-based and benchtop.
The PicoScope 4262 is fitted with second-generation hardware acceleration (HAL2). This speeds up areas of oscilloscope operation such allowing thousands of waveform updates 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.
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.
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 sub-10 µs rearm delay provided by digital triggering, together with segmented memory, allows up to 10,000 waveforms to be captured in a 20 ms burst.
The PicoScope 4262 offers an industry-leading set of advanced triggers including pulse width, runt pulse, windowed, logic and dropout.

Color persistence modes
Advanced display modes allow you to see old and new data superimposed, with new data 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, or custom display modes.

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.

PicoScope Waveform Navigator
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.

Serial bus decoding and protocol analysis
PicoScope can decode 1-Wire, ARINC 429, CAN, DALI, DCC, DMX512, I²C, LIN, Manchester, MIL-STD-1553, MODBUS, PMBus, PS/2, Quadrature, SBS Data, SENT Fast/Slow, SMBus, SPI-SDIO, UART, and USB 1.1 protocol data as standard, with more protocols in development and available in the future with free-of-charge software upgrades.
Multiple protocols can be captured and decoded, the only limit being the number of available channels (18 for MSO models). The ability to observe data flow across a bridge (such as CAN bus in, LIN bus out) is incredibly powerful.
The deep memory buffers make the PicoScope 2000B models ideal for serial decoding as it is possible to capture and decode many thousands of frames of data.

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.
