The test and measurement laboratory

The PicoScope 2205 MSO is more than a just another instrument — it’s the ultimate test and measurement laboratory. You can use your PicoScope 2205 MSO as a dual-channel oscilloscope, logic analyzer, protocol decoder, spectrum analyzer, function generator and an arbitrary waveform generator. Six professional-quality instruments in one compact, low-cost, USB-powered unit.

Mixed-signal capability / logic analyzer

The PicoScope 2205 Mixed-Signal Oscilloscope include 16 digital inputs so that you can view digital and analog signals simultaneously.

The digital inputs can be displayed individually or in named groups with binary, decimal or hexadecimal values shown in a bus-style display. A separate logic threshold from –5 V to +5 V can be defined for each 8-bit input port. The digital trigger can be activated by any bit pattern combined with an optional transition on any input. Advanced logic triggers can be set on either the analog or digital input channels, or both to enable complex mixed-signal triggering.

The digital inputs bring extra power to the serial decoding options.  You can decode serial data on all analog and digital channels simultaneously, giving you up to 18 channels of data.  You can for example decode multiple SPI, I²C, CAN bus, LIN bus and FlexRay signals all at the same time!

CANBus analysis in PicoScope

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.

signal generator

Arbitrary waveform and function generator

The PicoScope 2205 MSO has a built-in function generator (sine, square, triangle, ramp, DC level, white noise 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.

A 12 bit 2 MS/s arbitrary waveform generator (AWG) is also included. AWG waveforms can be created or edited using the built-in AWG editor, imported from oscilloscope traces, or loaded from a spreadsheet.

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.

Over 20 years ago Pico first 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 PicoScope 2205 MSO offers an industry-leading set of advanced triggers including pulse width, runt pulse, windowed and dropout.

PicoScope 2205 MSO Signal integrity

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, unlike most oscilloscope manufacturers, we publish our specifications in detail. The result is simple: when you probe a circuit, you can trust in the waveform you see on the screen.

PicoScope 2205 mixed signal oscilloscope kit

Powerful and portable

The ability to measure two analog signals of up to 25 MHz together with 16 digital signals of up to 100 MHz, combined with a 200 MS/s sampling rate and 48 kS buffer memory makes the PicoScope 2205 MSO a powerful mixed-signal oscilloscope.

The compact, USB-powered design means that this is one mixed-signal oscilloscope that can be used both on your desktop or in the field. While the ability to also use it as spectrum analyzer, function generator and arbitrary waveform generator gives you a complete test and measurement lab at a price you can afford.
