HP / Keysight / Agilent N5457A Overview
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.
Other oscilloscope solutions with serial bus triggering and protocol decode typically use software post-processing techniques to decode serial packets/frames. Using these software techniques, waveform- and decode-update rates tend to be slow (sometimes seconds per update), especially when you use deep memory, which is often required to capture multiple packetized serial signals.
