RS-232/UART Triggering and Har

Debugging systems that use an
RS-232 serial bus can be difficult,
unless your scope is capable of
triggering on and decoding the
RS-232 protocol. Traditional
methods of debugging serial
buses such as RS-232 include
manual bit counting. But this
visual technique of counting “1s”
and “0s” can be tedious and it is
prone to errors. 
Agilent Technologies’ serial
bus options for InfiniiVision
oscilloscopes offer powerful
triggering and provide unique
hardware-accelerated decoding
to help you debug embedded
designs with RS-232 and UART
serial buses faster. With the
industry’s fastest serial decode
update rates, you can more easily
find and debug random and
intermittent errors and signal
integrity problems that you could
easily miss using other serial bus
decode tools.
