Timing mode

In Timing mode, the latches on the analysis probe act like flow-through
buffers. The signals from the microprocessor go directly from the target
system to the logic analyzer, with a 1-ns channel-to-channel skew. The figure
on the following page shows the waveform diagram for Timing mode.
