analyzer and pattern generator

SQ Series overview

SQ devices are a series of 4 channels logic analyzers and digital pattern generators. They have an integrated memory (up to 4M points per channel) and a high speed USB interface to transfer signals from/to the host computer. A free application (ScanaStudio) is provided to analyze captured signals or create patterns to be generated. Generated signals may be arbitrarily created signals, or alternatively, user may play back previously captured signals

SQ devices oer an intuitive way of analyzing logic signals, backed with exciting features like enhanced ±35V input protection, adjustable input threshold, direct connection to RS232/485, CAN and LIN buses, ability to trigger on specific protocols (like a UART word or an I2C address). The signal generator was designed to be very versatile: Precise control over loop point can be achieved as well as the ability to generate arbitrary signals on any number of channels while recording the result on the others. SQ series’ input/output stage is fully protected while oering flexible options like Open Drain outputs and configurable pull up/down resistors. Furthermore, the digital signal generator has an adjustable output voltage from 1.8V to 5V, which covers most TTL, CMOS and LVCMOS applications. SQ Series is composed of four devices: SQ25, SQ50, SQ100 and SQ200. All have 4 channels that can be used to capture and/or generate logic signals. The table below shows the mains dierences between models:

Power requirements

SQ device Interfaces

SQ logic analyzer and pattern generator ports and interfaces are shown in the diagram below:

1. USB port (mini B)
2. Status LED
3. 4 channel probes connector

Principle of operation

ScanaQuad is also 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
Versatile trigger system
SQ series oer a state of the art trigger system. It’s composed of one FlexiTrig®trigger engines, each FlexiTrig engine can be used in one of those modes:

• Edge trigger
• Pulse trigger (with minimum and maximum pulse width)
• Timed logic sequence
• Protocol based trigger (e.g. I2C bus address or serial UART character)

Finally, an external trigger input and output is available via an accessory called TrigBox.
