Correlate Timing Across Digital Signals

Capturing multi-signal timing events requires simultaneous acquisition of many digital channels with deterministic time alignment to preserve true cause-and-effect relationships. The measurement setup involves probing related signals—such as clocks, data buses, enables, and control lines—and configuring timing mode acquisition so that all transitions are captured against a common time base. This allows engineers to observe how events propagate across functional blocks without skew introduced by sequential or fragmented measurements.

The test operates by applying complex trigger conditions to isolate timing relationships or multi-signal sequences of interest, followed by capturing long time windows of system activity. Engineers place timing markers on key transitions and directly measure time deltas between events across channels. This exposes causality, race conditions, setup/hold margin issues, and synchronization problems between interacting blocks in embedded and FPGA-based systems.

Multi-Signal Timing Correlation Solution

Multi-signal timing capture requires simultaneous, time-aligned acquisition of many digital signals and precise measurement of timing relationships to identify causality, sequencing, and synchronization issues across a system. Keysight's multi-signal timing correlation solution provides high channel density, deep timing memory, and flexible multi-signal triggering to capture long activity windows, correlate events across domains, and measure propagation delays, race conditions, and clock-domain interactions with deterministic timing accuracy.
