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.
