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, SIGMA is ready for other debugging features by software updates and add-on modules. SIGMA operates on a USB port and requires no external power supply.

SIGMA has been designed with most important real-life user requirements in mind:

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
Extensive condition definition options using logical functions (N)AND,(N)OR,(N)XOR

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.
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 - SIGMA 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 SIGMA 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 utility for SIGMA:

Frequency measurement - four independent channels with filtering and averaging
