Settings

SPI Settings

SPI Protocol Analyzer settings (TravelLogic series)
  • Settings:
    • Clock Latch: Rising / Falling data latch edge. A wrong setting can shift decoding. Default: Rising.
    • Chip Select: Active Low / Active High. Default: Active Low.
    • Data Bits: Data bits per character (4–8). Default: 8.
    • Sample Rate: SPI analysis sample rate (choices vary by product; e.g. TravelLogic/MSO: 20/100/200 MHz/1 GHz). Too low may fail to decode high-speed SPI. Default: 3rd list item (TravelLogic/MSO: 200 MHz).
    • Bit Order: MSB / LSB. A wrong setting reverses bit order within each word. Default: MSB.
    • Word Wrap: How decoded results wrap/segment. 8 data wraps every 8 data words; All block data shows a whole transfer block (e.g. one CS-active period). Default: 8 data.
