13.1 Basics of protocol analysis
With the MXO 4 oscilloscope, you can decode selected protocols.
With dual-path protocol analysis, you can set the instrument sample rate for the wave-
form path and the oscilloscope automatically uses another internal decoupled sample
rate for the decoding path. Even with very slow sample rates, the protocol data is cor-
rectly decoded.
With the MXO 4, you can use deep memory to capture more packets. The oscilloscope
can capture long time periods where the cause and result are distanced in time. Over
the entire capture, signal detail is time-correlated with packet content for fast debug.
