ڦ Connect to TTL interface
Connect appropriate signals of UART, I2C and SPI to the TTL port of analyzer
using attached probe cable.
ڧ External Trigger Terminal
External trigger input level is LVTTL (3.3V). External trigger output is open
collector output type and pulled up in 5V by 10KΩ in the analyzer.
Attached 5-wire TTL prove can be used for connection of external trigger. To
use the TTL proves for both TTL and external trigger, prepare additional one.

5wire TTL probe (LE-5LS)
If the target devices are easily affected by radiation noise from the
analyzer, try to use the shielded cable and add the ferrite core on the
cable.
