SIGMA 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. Moreover, it is ready for other debugging features by software updates and add-on modules. 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 inputs/100 MHz and 4 inputs/200 MHz 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

Personal computer requirements:

Windows 98 and higher (XP recommended), Pentium 750MHz or faster CPU, at least 256 MB RAM.
Also supported on Linux using WINE.
