07 | Keysight | Phase Noise X-Series Measurement Application N9068A & W9068A - Technical Overview Integrated noise measurement Different applications require differ - ent measures for evaluating phase noise behaviors. In the digital world, root-mean-square (rms) phase devia - tion/jitter (in degrees or radians) and rms phase jitter (in seconds) are used more frequently to evaluate the sta - bility of a high-frequency clock. On the other hand, residual FM is more important to amplifier designers and manufacturers. The X-Series signal analyzers make these measurements easy with advanced marker functions (Figure 4). The band marker functions enable you to: – Characterize phase noise related behaviors from different angles for various applications – Adjust bandwidth for integrating noise power (in dB/bandwidth Hz) 1 or averaging noise power density (in dB/Hz) 1 by using advanced band markers on the log plot – Calculate rms phase deviation (or residual PM) in degrees or radi - ans – Calculate rms jitter in seconds – Calculate the residual FM in Hz – View numeric marker readings for calculated results – View readings of multiple mark - ers Multiple spurious peak search The marker menu supports the spurious peak search function1, peak, next peak, right peak, and left peak. The “raw” trace (yellow) indicates that spurious signals are automati - cally detected and separated. The “smoothed” trace (light blue) remains after the spurious products are re - moved from the “raw” trace. Advanced scaled delta markers The delta marker menu enables you to select various scales of: – Absolute/normal (x Hz) – Octave slope (2x Hz) 1 – Decade slope (10x Hz)1 1. Requires Option AFP or ATP for previ - ously purchased equipment.
