PicoScope 4262

16 bit high resolution oscilloscope

PicoScope 4262 Features

fast waveform update rate

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 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 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.

PicoScope color persistence mode

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.

Oscilloscope mask limit test

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.

waveform buffer

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.

CAN bus serial decoding

Serial bus decoding and protocol analysis

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.

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.
