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
