SPI Bus Signal Analysis Function

Analysis Function

Signal Input

CH1:

Clock signal (SCK)

CH2:

Data1 (MOSI)

CH3:

Data2 (MISO)

CH4:

CS signal (SS)

Detailed Data Display Mode

Displays the time from the Reference Point, the data (select binary or hexadecimal

display), and the CS signal state.

Waveform and Data Display Mode

Simultaneously displays the data (hexadecimal) and the waveform

Number of Data Points That Can Be Analyzed

Up to 40000 bytes (20000 bytes before and after the reference point)

Search Function

Pattern Search

Searches data that matches the specified data pattern.

Indefinite Data Search

Searches indefinite data.
