Timing and synchronization are crucial in building test and measurement (T&M) systems, which makes the IEEE 1588 Precision Time Protocol’s ease of use and high performance especially attractive to system designers. This white paper offers an overview of the benefits IEEE 1588 brings to T&M systems, especially when paired with LXI Class B instrument capabilities, and illustrates how these capabilities can be integrated into instruments that can serve as powerful building blocks for creating high performance test systems.
