This product has been discontinued by the manufacturer. Here you get to the replacement product SQ200.
SQ Logic Analyzer Series
With the logic analyzer of the SQ series (ScanaQuad) you can acquire, analyze and generate logic signals on 4 channels with sampling rates of up to 200 MHz. They are connected via USB to a computer that runs the free ScanaStudio software to display, decode and analyze acquired signals.
With 4 channels, the device offers users with a small budget all the requirements that are needed for the analysis and debugging of serial protocols. The SQ series supports a variety of protocols such as SPI, I2C, USART, 1-wire, CAN, LIN, I2C, RS232, RS485, TWI and much more

Capture and generate logic signals
ScanaQuad is able to generate captured signals (play back), or build genuine arbitrary test patterns, like UART, SPI or I2C packets. It can also be used to compose and generate Frequency modulation (FM) signals and pulse width modulation (PWM) signals. Thanks to the mixed mode, SQ devices can even capture and generate digital signals simultaneously. Mixed mode is specifically designed to allow engineers to stimulate a circuit with test signals and capture its response.
Embedded memory
SQ series logic analyzers come with an embedded memory to store captured samples, as well as the patterns to be generated. Hence, SQ devices do not live-stream captured signals over USB. This has one big advantage: the performance do not depend on the host computer USB port performance
Powerful trigger options
- Edge trigger
- Logic change on one or various channels
- Trigger on a sequence of timed logic signals
- Trigger on a protocol word or event (like serial word or I2C address acknowledge)
Typical applications
By combining logic analyzer and pattern generator capabilities in a single low price device, SQ is a perfect solution for students and small design houses. For more channels and more performances, check SP series logic analyzers.
