PicoScope 3404D 70MHz 4-Ch 8-bit PC Oscilloscope (PP963)

Pico Technology’s compact PicoScope 3404D is a powerful 4-channel 70MHz PC oscilloscope that is small enough to easily fit laptop bag, yet while offers desktop performance specifications.

Specification Summary:

• 70MHz analog bandwidth
• Up to 1 Gsample/s real-time sample rate
• 128 megasample signal memory
• 100,000 waveforms per second
• Arbitrary Waveform Generator and Function Generator for built-in test signals
• USB 3.0 connected and powered – external power supply not needed!
• Serial decoding and mask testing included – not extra cost!
• PicoScope 6 software – provided free – is compatible with Windows, Linux and Mac software

Supported by the advanced PicoScope 6 software, these devices offer an ideal, cost-effective package for many applications, including embedded systems design, research, test, education, service, and repair.

High bandwidth and sampling rate

Despite its a handy size and low cost, the performance is outstanding: a real-time sampling rate of up to 1 GSa/s is matched for with an Equivalent Time Sampling (ETS) mode for repetitive signals of 10 GS/s.  The deep memory helps sustain these rates on long time-bases. 

Zoom buttons and an overview window lets you magnify and reposition the display by simply dragging with the mouse or touchscreen.   

Serial bus decoding & protocol analysis

The PicoScope 3404D includes serial decoding capabilities as standard. The decoded data can be displayed in the format of your choice: In graph, In table, or both at once.

In view format shows the decoded data (in hex, binary, decimal or ASCII) in a databus 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 window 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, search for frames with specified properties, or define a start pattern to signal when the program should list the data.  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 hexadecimal data into user-defined text strings.

PicoScope can decode I²C, RS-232/UART, SPI, I²S, USB, FlexRay, LIN and CAN bus data.  Expect this list to grow over time with future free software upgrades. 

Spectrum Analyzer

With the click of a button you can display a spectrum plot of selected channels up to the full bandwidth of the oscilloscope. A full range of settings gives you control over the number of spectrum bands, window types, and display modes (instantaneous, average, or peak-hold).

You can display multiple spectrum views with different channel selections and zoom factors, and place these alongside time-domain 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. You can even use the AWG and spectrum mode together to perform swept scalar network analysis.

Signal Integrity

Most oscilloscopes are built down to a price. PicoScopes are built up to a specification.

Careful front-end design and shielding reduces noise, crosstalk and harmonic distortion. Years of oscilloscope design experience can be seen in improved bandwidth flatness and low distortion. We are proud of the dynamic performance of our products, and publish their specifications in detail.

The result is simple: when you probe a circuit, you can trust in the waveform you see on the screen.

USB Connectivity

The USB connection not only allows high-speed data acquisition and transfer, but also makes printing, copying, saving, and emailing your data from the field quick and easy. USB powering removes the need to carry around a bulky external power supply, making the kit even more portable for the engineer on the move.
