    • Full speed state analysis up to 66 MHz external bus frequency
    • Cache enabled trace through Instruction Trace Reconstruction (ITR) which can decode the instructions when the cache is on.
    • Supports the 60X compatible bus mode (SDRAM, GPCM) and Single 8260 mode (SDRAM, GPCM).
    • Disassembly decodes and displays the processor's instruction set mnemonics.
    • Symbolically identifies all processor bus cycles
    • Acquired data can be linked directly to HLL source files for source level debug
    • Up to 125 ps timing resolution enables detailed analysis of setup and hold times, edge-to-edge relationships, control timing, etc.
    • All data acquired by the logic analyzer is time stamped to enable accurate time correlation of code execution to other system busses or hardware activity.


    Engineers can design a probe interface directly into the system under test. This allows the greatest control of probe loading and provides the most mechanically robust connection. Tektronix recommends designing the P6860 connectorless or P6434 probe connectors into prototype models. Third party breakout boards are also available, providing an alternative probing method.
