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, division by 2 ... 256)
• 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 is 40 MHz at 1:1 duty
• 15 inputs + 1 synchronous clock input (trailing or falling edge), max. clock speed is 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 N-th occurence of the condition

Standard triggering options in the 8 inputs/100 MHz and 4 inputs/200 MHz modes - triggering on the input signal edge.

Trigger point can be placed to 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 disc.
• 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 protocol analyzers: UART, I2C and SPI. USB protocol analyzer (Low-Speed and Full-Speed) can be purchased separately.
• 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.

User-friendly device

• Easy connection to PC - the comfortable USB interface.
• Low power - no power supply adaptor 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, if ... (you know well what happens to any electronic designer sometimes :-)
• Upgradability - due to flexible design based on Xilinx FPGAs it will be possible to upgrade and enhance SIGMA2 functionality by simple software update (e.g. frequency, period and duty cycle measurement)
• Small, lightweight and compact.

More than logic analyzer

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

Existing software utilities for SIGMA2:

• Frequency measurement - four independent channels with filtering and averaging
• INSIDER - flexible monitoring/debugging tool for debugging MCUs and FPGAs (significantly enhanced replacement of discontinued product INSIDER).
