SQ Series Logic analyzers

4 channel logic analyzers and pattern generator

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.

Being 4 channels makes it a low budget device, while still covering all serial protocols analysis and debugging needs. That includes (but not limited to): SPI, I2C, USART, 1-Wire, CAN, LIN, I2C, RS232, RS485, TWI and much more (click here for full list of supported protocol decoders).

SQ series family overview

SQ logic analyzer series is composed of 4 devices: SQ25, SQ50, SQ100 and SQ200. All devices have 4 channels, offer the possibility to capture and generate signals and work with logic signals in the range of 1.8V to 5V. The table below shows the main differences between the four models:

SQ25

SQ25 Logic Analyzer

  • 25 MHz max. sampling rate
  • Memory: 256 Kpts / channel
  • Simple trigger options (Edge, logic level and pulse)
  • No protocol based trigger, no trigger sequences
  • No differential input pairs

SQ50

SQ50 Logic Analyzer

  • 50 MHz max. sampling rate
  • Memory: 1 Mpts / channel
  • Simple trigger options (Edge, logic level and pulse)
  • Protocol based trigger
  • Arbitrary trigger sequence
  • No differential input pairs

SQ100

SQ100 Logic Analyzer

  • 100 MHz max. sampling rate
  • Memory: 2 Mpts / channel
  • Simple trigger options (Edge, logic level and pulse)
  • Protocol based trigger
  • Arbitrary trigger sequence
  • 1 differrential input pair

SQ200

SQ200 Logic Analyzer

  • 200 MHz max. sampling rate
  • Memory: 4 Mpts / channel
  • Simple trigger options (Edge, logic level and pulse)
  • Protocol based trigger
  • Arbitrary trigger sequence
  • 2 differrential input pair

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.

  • Embedded systems
  • Firmware development and debugging
  • Educational work
  • Serial protocols analysis, like I2C, SPI, UART or 1-Wire (non exhaustive list)
  • Reverse engineering

Benefits

  • Get quick insight into your serial communication application.
  • Software lets you view decoded signals in many different levels of abstractions (Packets or detailed bits and bytes)
  • Device performance do not depend on USB connection bandwidth
  • Software running on Windows, macOS and Linux.
  • Software is intuitive and very easy to use.
  • Generate test patterns to stimulate a system without any other equipment.
