High-speed USB digitizer
The PicoScope 6407 Digitizer is a compact USB plug-in device that turns your PC or laptop into a 4-channel, high-speed digitizer / PC oscilloscope.
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.
The spectrum view plots amplitude against frequency and is ideal for finding noise, crosstalk or distortion in signals. The spectrum analyzer in PicoScope is of the Fast Fourier Transform (FFT) type which, unlike a traditional swept spectrum analyzer, can display the spectrum of a single, non-repeating waveform.
A full range of settings gives you control over the number of spectrum bands (FFT bins), window types, scaling (including log/log) and display modes (instantaneous, average, or peak-hold).
You can display multiple spectrum views alongside oscilloscope views of the same data. A comprehensive set of automatic frequency-domain measurements can be added to the display, including THD, THD+N, SNR, SINAD and IMD. A mask limit test can be applied to a spectrum and you can even use the AWG and spectrum mode together to perform swept scalar network 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.
Some oscilloscopes struggle when you enable deep memory; the screen update rate slows and controls become unresponsive. The PicoScope 6407 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 2.5 billion samples every second.
PicoScope oscilloscopes manage deep memory better than competing oscilloscopes, both PC-based and benchtop.
The PicoScope 6000 Series is fitted with 3rd generation hardware acceleration (HAL3). This speeds up areas of operation such as allowing waveform update rates in excess of 130,000 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.
An important specification to understand when evaluating oscilloscope performance is the waveform update rate, which is expressed as waveforms per second (wfms/s). While the sample rate indicates how frequently the oscilloscope samples the input signal within one waveform, or cycle, the waveform capture rate refers to how quickly an oscilloscope acquires waveforms.
Oscilloscopes with high waveform capture rates provide better visual insight into signal behavior and dramatically increase the probability that the oscilloscope will quickly capture transient anomalies such as jitter, runt pulses and glitches – that you may not even know exist.
PicoScope oscilloscopes use hardware acceleration to achieve over 130,000 wfms/s.
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.
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.
