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.
The PicoScope 6407 is a compact USB plug-in device that turns your PC or laptop into a 4-channel, high-speed digitizer. The PicoScope 6407 differs from the rest of the PC oscilloscopes in the PicoScope 6000 series in that it has high-bandwidth 50 Ω inputs with fixed ±100 mV input ranges and SMA connectors. Larger input signals can be accommodated with the use of external attenuators (see accessories).
With a 1 GHz bandwidth complemented by a real-time sampling rate of 5 GS/s, the PicoScope 6407 can display single-shot pulses with 200 ps time resolution.
The 1-gigasample buffer on the PicoScope 6407 can hold two 100 ms captures at the maximum sampling rate of 5 GS/s. The PicoScope 6407 is suited to a wide range of high-speed applications including:
The software development kit (SDK) allows you to write your own software and includes drivers for Microsoft Windows and beta drivers for Apple Mac (OS X) and Linux (including Raspberry Pi).
Example code shows how to interface to third-party software packages such as Microsoft Excel, National Instruments LabVIEW and MathWorks MATLAB.
The drivers support USB data streaming, a mode which captures gap-free continuous data over USB direct to the PC’s RAM or hard disk at rates of over 10 MS/s and capture size is limited only by available PC storage. Sampling rates in streaming mode are subject to PC specifications and application loading.
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 reduced rearm delay provided by digital triggering, together with segmented memory, allows the capture of a new waveform every microsecond until the buffer is full.
The PicoScope 6000 Series offers an industry-leading set of advanced triggers including pulse width, runt pulse, windowed, logic and dropout.
The PicoScope 6407 has a built-in 20 MHz function generator (sine, square, triangle, DC level, white noise, PRBS and others). As well as basic controls to set level, offset and frequency, more advanced controls allow you to sweep over a range of frequencies. Combined with the spectrum peak hold option this makes a powerful tool for testing amplifier and filter responses.
Trigger tools allow one or more cycles of a waveform to be output when various conditions are met such as the scope triggering or a mask limit test failing.
The PicoScope 6407 also includes a 12 bit 200 MS/s arbitrary waveform generator (AWG). AWG waveforms can be created or edited using the built-in AWG editor, imported from oscilloscope traces, or loaded from a spreadsheet.
