Agilent/Keysight E5850A

The Agilent/Keysight E5850A is a Time Correlation Fixture that enables time-correlated measurements between Infiniium oscilloscopes and logic analysis systems. It automates cross-triggering setup and eliminates timing skew between instruments, allowing synchronized waveform analysis on a single display. Global markers measure time across all displayed signals, with oscilloscope time markers tracking logic analyzer markers in real time.
