Details - USB Logic Analyser

• Extremely large event memory
  • 256 Megabit SDRAM memory is enhanced using real-time hardware compression which allows up to 14,680,064 samples to be stored or more than 45 minutes of records.
• Flexible input/sample speed options
  • 16 inputs at 50 MHz
  • 8 inputs at 100 MHz
  • 4 inputs at 200 MHz
  • 16 inputs with 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
  Various trigger options with 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 using logic functions (N)AND,(N)OR,(N)XOR
  • In 8 inputs/100 MHz and 4 inputs/200 MHz modes, standard edge triggering
  • Trigger point can be placed anywhere in the recorded events
• Advanced software
  • Protocol Analyzer for UART included
  • New Protocol Analyzers for SDRAM, I2C, and SPI included
  • Full-Speed and Low-Speed USB analyser can be purchased separately.
  • Ready for easy multi-language support (not applicable for plugins).
  • Waveforms can be saved and loaded to a file.
  • Waveforms can be exported to a text file for further processing.
  • Waveforms can be printed.
  • 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.
  • Flexible control using mouse and keyboard
  • PC requirements: Windows 98 and higher (XP recommended), Pentium 750MHz or faster CPU, at least 256 MB RAM.
• Easy to Use
  • The USB Logic Analyser simply connects to any PC USB port
  • USB Logic Analyser is powered by USB bus, so no power supply is needed
  • USB Logic Analyser probe mode - SIGMA displays momentary logic levels on all 16 inputs.
  • The USB Logic Analyser has LED indicators for instant status checking.
  • USB Logic Analyser is fast, with 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
  • Flexible design based on Xilinx FPGAs allow software upgrades to enhance SIGMA functionality e.g. frequency, period and duty cycle measurement
  • Small, lightweight and compact.
