200MHz Logic Analyzer, 256Mb SDRAM, up to 16 channels, USB US$150.00

200MHz Logic Analyzer, 256Mb SDRAM, up to 16 channels, USB

  • Extremely large event memory (256 megabits = over 14 million samples)
  • Real-time hardware data compression
  • Up to 200 MHz sample speed
  • Up to 16 inputs
  • Flexible trigger options
  • "Logic probe" mode
  • Controlled and powered by USB (Full-Speed, 12 Mbps)
  • Advanced software for Windows and Linux
  • SIGMA2 is a powerful, fast, flexible, user-friendly and cost-effective logic analyzer with extremely large event memory, real-time hardware compression and complex trigger logic. It operates on a USB port and requires no external power supply.

    Logic Analyzer Features

    Extremely large event memory

    256 Megabit SDRAM memory is used and further enhanced using a real-time hardware compression which allows for 14,680,064-sample storage or for more than 45 minutes of recording.

    Flexible input/sample speed options

    • 16 inputs at 50 MHz (and lower sample speed)
    • 8 inputs at 100 MHz
    • 4 inputs at 200 MHz
    • 16 inputs sampling on change of an input signal (asynchronous clock) trailing, falling or both edges; max. clock speed 40 MHz at 1:1 duty
    • 15 inputs + 1 synchronous clock input (trailing or falling edge); max. clock speed 49.9 MHz

    Complex trigger logic

    Many various triggering options in the 16 inputs/50 MHz mode:

    • Any value or edge on any input condition
    • Defined duration of the condition ("longer than" and/or "shorter than")
    • Sequence of two different conditions
    • 16-bit counter triggering after Nth occurence of the condition
    • Extensive condition definition options using logical functions (N)AND,(N)OR,(N)XOR

    • Standard triggering options in 8-input/100MHz and 4-inputs/200MHz modes triggering on the input signal edge.
      Trigger point can be placed at any position of recorded events from the very beginning to the end.

    Advanced software

    • Ready for plugins both ASIX and user-definable, e.g. protocol analyzers (like I2C, SPI, UART, SDRAM, Full-Speed and Low-Speed USB)
    • Ready for easy multi-language support (not applicable for plugins)
    • Waveforms can be saved and loaded to a computer hard drive
    • Waveforms can be exported to a text file for further processing
    • Waveforms can be printed on a printer
    • Flexible trace definition (any combination of input signals and constant logic levels) and trace representation (signals, buses binary, octal, decimal, hexadecimal, ASCII). Input signal can be used in more than one trace.
    • Free UART, I2C and SPI protocol analyzers
    • Flexible control using mouse and keyboard

    • PC requirements: Windows 98 or higher (including 32- and 64-bit Windows 7; see user manual), Pentium 750MHz or faster CPU, at least 256 MB RAM.
      Also supported on Linux using WINE.

    User-friendly device

    • Easy connection to PC the comfortable USB interface.
    • Low power no power supply adapter needed.
    • Logic probe mode SIGMA2 displays momentary logic levels on all 16 inputs.
    • Detailed LED indication for instant and intuitive status checking.
    • Fast operation less than 1-second delay for any selected view. (Full data download takes about 90 seconds.)
    • Input threshold level is suitable for TTL, LVTTL and 2.7 to 5.5V CMOS levels.
    • Replaceable input buffers DIP parts in socket allow for easy replacement.
    • Upgradability due to flexible design based on Xilinx FPGAs, it will be possible to upgrade and enhance SIGMA2 functionality by simple software updates (e.g. frequency, period and duty cycle measurement).
    • Small, lightweight and compact.

    More than a logic analyzer

    Additional debugging features will be available via software upgrades and add-on modules.

    Existing software utilities included with SIGMA2:

    • Frequency measurement four independent channels with filtering and averaging
    • INSIDER flexible monitoring/debugging tool for debugging MCUs and FPGAs
