  • Page 106: Calculations And Masks

    Chapter 5 Analyzing Analysis of PDV Measurements Calculations and Masks TimeMonitor PDV includes two computations for packet timing data PDV analysis, packetTDEV and packetZTIE. These computations are based on - but are not identical to - floor-based calculations such as minTDEV, percentileTDEV, and ZTIE with minimum transit time packet selection.
  • Page 107 Chapter 5 Analyzing Analysis of PDV Measurements As mentioned above, the packetTDEV calculation is adjusted when "Optimal" is selected. The analysis in this "Optimal" case is a deeper look into the packet delay data in an attempt to model network characteristics which in a simpler analysis would be overlooked.
  • Page 108 Chapter 5 Analyzing Analysis of PDV Measurements To illustrate this, consider the packetZTIE analysis shown in Figure 5-1 below. Figure 5-1. packetZTIE Analysis of PDV Data Where Mask is Met Also consider the MTIE analysis of a PTP slave measurement, as shown in Figure 5-2 below.

    Chapter 5 Analyzing Analysis of E1 Measurements Analysis of E1 Measurements The Standard variant of TimeWatch is designed to perform an MRTIE measurement between two external clock inputs. The inputs are independent and each can be either a 2.048 MHz clock or an E1 2.048 Mbit/s signal. The probe uses an internal TIE measurement engine that compares two external inputs at 80 samples per second (80Hz) and calculates the relative phase.
