The ScanaQuad SQ200 is a 4-channel logic analyser and digital pattern generator that helps you capture, decode, and debug digital signals on your embedded systems. With 200 MHz sampling, 4 M samples per channel, and 30+ built-in protocol decoders, it handles everything from simple edge triggers to complex multi-step protocol-based triggering.
The SQ200 can capture and generate simultaneously — stimulate your circuit with test patterns while monitoring its response. The free ScanaStudio V3 software runs natively on Windows, macOS, and Linux.
Key Features
- 200 MHz Max Sampling Rate – High-speed capture for fast digital signals
- 4 Input/Output Channels – Capture, generate, or both simultaneously
- 4 M Samples per Channel – Deep memory for long captures
- 30+ Protocol Decoders – I²C, SPI, RS232, CAN, 1-Wire, JTAG, and more (open source)
- Protocol Trigger – Target specific I²C addresses, CAN frame IDs, or custom patterns
- ±35V Input Protection – Robust inputs for real-world circuits
- Adjustable I/O Voltage – Match your circuit's logic levels

Jargon buster
Plain-language definitions for the technical terms used above.
- 1-Wire
- 1-Wire is a communication method where devices share a single data line, often with each device having its own address. It matters because several temperature modules can be connected to one microcontroller pin instead of needing a separate pin for each probe.
- Differential input
- A measurement method where the board reads the voltage difference between two input wires instead of measuring one wire compared with ground. This is useful for small sensor signals and noise reduction, but both input voltages still need to stay within the board’s allowed range.
- differential signal
- A measurement taken between two input wires rather than between one wire and ground. This matters for precision sensors because it can reduce noise and lets the ADC read very small voltage differences more accurately.
- JTAG
- JTAG is a hardware debugging and programming interface used to inspect and control chips at a low level. It matters for advanced development because it can help diagnose firmware problems that are hard to see through normal serial output.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
