IP Session shows information for Layer 1 & 2, Video, Audio, Data, PTP and NMOS. The user can verify data streams and check syntax information. 

The Layer 1 & 2 show link status along
with Layer 2 Metrics for Received Bytes,
CRC Errors or Frames Errors and
indication of Undersized Packets.

The Video tab shows IP address, port
number and RTP Layer 5 information such
as Marker, Payload Type, Sequence
Number and Timestamp.

The Audio tab shows shows IP address,
port number and RTP Layer 5 information
such as Marker, Payload Type, Sequence
Number and Timestamp.

The Data tab shows shows IP address,
port number and RTP Layer 5 information
such as Marker, Payload Type, Sequence
Number and Timestamp.

This display provides PTP syntax
information including Grandmaster ID,
Domain, Clock Class/ Accuracy/Variance.
Priority 1 & 2 values along with message
rates.

NMOS information is displayed showing
NMOS server address and last SDP file
sent.

Packet Interval Time Histogram shows a distribution of how the packets have arrived at the input to PRISM. Certain types
of senders will have a characteristic distribution of the packets that can be helpful in diagnosing issues with streams.
Requires option IP-MEAS to be installed in the instrument.

IP Graphs allows for metrics of the IP stream to be plotted from 60 seconds to 24 hours. This allows the user to track the
health of the stream over time and identify possible errors with the signal. IP graphs provide information on Total Bitrate,
Session Bitrate, PIT, RTP Sequence Error and other graphs dependent on the type of stream being decoded. Requires
option IP-MEAS to be installed in the instrument.

Stream Timing can be used to track the timing of the input signal to the PTP reference to ensure that the Sender of the
stream is locked to PTP and to track the variations across the network of the stream by PRISM for video, audio and data.
Requires option IP-MEAS to be installed in the instrument.

PTP Graphs provide a plot of the forward and reverse paths of the PTP messages across the network. The user can select a
window between 60 seconds to twenty four hours to monitor the variations over time. Requires option IP-MEAS to be
installed in the instrument.
