Connect to TTL
To measure UART, I2C and SPI, set “Measurement port: TTL (5.0V) ~(1.8V)” at “
Interface
” setting.
2.3 Measurement Port
Connect appropriate signals to the TTL port of analyzer using the attached 5-line TTL probe cable (model: LE-
5LS).
TTL port is 2.54mm pitch 10 pin MIL box type connector. Use the one equivalent to “HIF3FC-10PA-2.54DS(71)” of
HIROSE Electric. Co., Ltd.

“I” indicates an input to the analyzer. “O” indicates an output from the analyzer.
If it is a master simulation, SS and SCK will be output (O). And, if it is a slave simulation, they will be input (I).
