THE deep memory oscilloscope

PicoScope 3000E Series oscilloscopes have waveform capture memories of up to 2 billion samples – many times larger than competing scopes. Deep memory enables the capture of long-duration waveforms at maximum sampling speed which is invaluable for capturing signals ranging from fast serial data through to complex power supply start-up sequences.  The waveform shows a capture of 500 million samples with a zoom factor of 10,000 to reveal details of individual pulses.

As well as long, deep captures PicoScope lets you divide the capture memory up to 40,000 segments. You can set up a trigger condition to store a separate capture in each segment, with as little as 700 ns dead time between captures (an effective rate of 2 million waveforms per second). This is ideal for applications such as laser and radar where there are often long gaps between pulses. Whether you have captured one long waveform or thousands of shorter ones, PicoScope has an array of powerful tools to manage and examine all of this data.

Other functions included such as mask limit testing and color persistence mode, PicoScope software enables you to zoom into your waveform up to 100 million times. The Zoom window allows you to easily control the size and location of the zoom area. Other tools, such as the waveform buffer, serial decoding and hardware acceleration work with the deep memory, making the PicoScope 3000E Series a powerful, compact package

Waveform buffer and navigator

Have you ever seen a glitch on an oscilloscope screen but by the time you stop the scope it has gone? PicoScope can store the last 40,000 oscilloscope or spectrum waveforms in its circular waveform buffer, effectively letting you turn back time to find that elusive waveform.The buffer navigator provides an efficient way of viewing, navigating and searching through waveforms.  The PicoScope 3000E also features hardware-based trigger time stamping so the gap between each waveform is displayed in high resolution. Tools such as mask limit testing and measurement limits can also be used to scan through each waveform in the buffer automatically with options to only show those that pass or fail - no need to search for that needle in a haystack. More advanced tools such as serial decoding and DeepMeasure work to analyze data packets or events across all waveform buffers in the deep memory, making the PicoScope 3000E Series some of the most capable oscilloscopes on the market.

Hardware acceleration engine (HAL4)

Some oscilloscopes struggle when you enable deep memory; the screen update rate slows and the controls become unresponsive. The PicoScope 3000E Series avoids this limitation with the use of a dedicated fourth-generation hardware acceleration (HAL4) 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 up to 2 billion samples every second.

The hardware acceleration engine eliminates any concerns about the USB connection or PC processor performance being a bottleneck.

THE oscilloscope for measurements and math

Measurements: Introduction

PicoScope 7 provides dozens of automated measurements both for the oscilloscope and spectrum, not just standard ones like frequency but more complex ones such as overshoot, edge count, phase, power factor, THD and SINAD.  Statistics can be displayed to show the Average, Mean, Maximum, Minimum, Standard Deviation and a count of the number of waveforms.  Measurements are highly configurable allowing you to measure across the whole waveform, between rulers or just a single cycle.  

Measurements: pass/failure limits

PicoScope software offers pass/failure limits for any measurement. This gives a visual indication within the measurement window whenever the measurement result goes above or below a specified value. Pass/failure limits can be combined with actions to immediately alert the user or execute other actions when a measurement threshold has been exceeded, either above or below set limits. By filtering the waveform buffer to show only those waveforms failing a measurement limit, you can quickly identify points of interest out of the thousands of waveforms captured in the deep memory of your PicoScope.
