Product Features
- All necessary clocks are passed through by the preprocessor to the logic analyzer to ensure that data is captured at the correct time.
- Software is shipped with the product that automatically configures the logic analyzer and generates labels for address, data, and status signals.
- The included disassembler displays execution traces in 68040 or 68060 microcontroller mnemonics.
- Instructions which are pre-fetched but not executed are marked in the trace display.
- Three modes of operation are available.
Data Sampling modes
- State-per-transfer provides a complete display of all bus activity
- State-per-clock filters out wait and idles states
- Timing analysis up to 500 MHz; channel skew: 1 ns
