• IP measurement 2110-21, PIT histograms, timing option
• For Phabrix QxL series
• Advanced media timing – video
• Advanced media timing – video latency
• Inter-packet timing

The Phabrix PHQXLO-IP-MEAS is an IP measurement 2110-21, PIT histograms, and timing option for the Phabrix QxL series. An advanced engineering suite of tools for ST 2110 analysis and debug offers the provision of up to four simultaneous dual Packet Interval Timing measurement windows per input for easy visualization of network congestion and sender packet distribution with max, mean and min inter-packet arrival times. Also included is detailed data reporting of flow packet, clock rates and PTP timing relationship, as well as the measurements of the ST 2110-21 Network Compatibility model (CINST) and Virtual Receiver Buffer Model (VRX). Advanced measurement of IP flow latency and RTP clock timing relationships for debug of Audio, Video and ANC alignment, source PTP and encapsulation are featured.

• Time of first received packet of a frame (video timing)
• Receiver buffer margin with respect to TRO default
• Sender RTP offset

• Numerical display of Mean, Min, and Max latency measurements
• Measured RTP clock/s, timestamp/s, and RTP clocks/timestamp interval
• Numerical display of video to audio and ANC relative latency measurement

• Stream health reporting using histogram to show the distribution of inter-packet arrival times
• Simultaneous reporting of ST 2022-7 primary and secondary flow
• Packet counts (log or linear scales) mapped against arrival times
• Easy diagnosis of congestion with max, mean, and min inter-packet arrival times

• ST 2110-21 measurement of network compatibility model (CINST) and virtual receiver buffer model (VRX)
• User control of VRX buffer read-schedule timing
• User control of CINST buffer drain rate
