SQ series have been replaced by the SE254

The SQ series have been discontinued and replaced by the newer SE254 Education/hobbyist oriented device.

We continue to support the SQ series, but we recommend using the SE254 series for new projects that require simple, low cost, 4 channel logic analysis. If you have any questions or need assistance with the transition, please contact us.

ScanaQuad Series

4 Channels logic analyzer

SQ series (ScanaQuad) logic analyzer lets you capture, analyze and generate logic signals on 4 channels, at sampling rates up to 200MHz. They connect via USB to a computer running our free ScanaStudio software to display, decode and analyze captured signals.

Compatibility with Windows 11 and core isolation

Latest version of SQ driver is not compatible with windows 11 core isolation feature. If you are using Windows 11 with core isolation enabled, you will need to disable it in order to use SQ logic analyzer with the original driver. If you can't disable core isolation (e.g. for security reasons), you can use this utility to modify SQ Device USB PID to the default FTDI PID. This will allow you to use the SP209 with the FTD2XX driver, which is compatible with Windows 11 core isolation.
