Triggering and Hardware-Based Decode (N5457A) for IniniiVision Oscilloscopes Data Sheet Features: – RS-232/UART serial bus triggering –RS-232/UART hardware-based protocol decoding – Real-time frame and error totalize counters

tedious and it is prone to errors. could easily miss using other serial bus decode tools. when you use deep memory, which is often required to capture multiple packet ized serial signals. Figure 1. Deining the RS232/UART protocol structure
