: Transport Layer Analysis 

This  section  describes  the  tools  available  for  assessing  video  integrity  for  transmission  and  for 
locating sources of jitter. 

The facilities described here are added by installing the EYE_SD, EYE_HD or EYE_3G options. 
EYE_SD just supports SD video; EYE_HD supports SD and HD; while EYE_3G supports SD, 
HD and 3G. 

M.1  Overview 

The  various  measurements  and  assessment  discussed  in  this  section  result  from  analysis  of  the 
data carrier signal.  

The characteristics of this analog signal are determined through time equivalent sampling. After 
an  initial  set-up  period  in  which  the  sampling  builds  up  sufficient  data,  it  becomes  possible  to 
determine such parameters as the signal amplitude, unit interval, rise time, fall time of the signal, 
together  with  information  about  undershoot,  overshoot,  noise  and  jitter  in  the  signal  and  an 
estimate  of  the  cable  length  (see  Section  M.5).  It  is  also  possible  to  identify  the  waveband  in 
which jitter occurs, which can help in identifying its source. 

These are all parameters that affect the integrity of any transmission and ultimately whether the 
receiver will be able to interpret the signal sufficiently accurately to display the desired images. 
Most of them are also subject to limits specified in transmission standards. 

The analysis of these parameters is carried out with the aid of a dedicated Eye/Jitter card which 
needs  to  be  added  the  OTR  1001,  along  with  supporting  software.  The  data  carrier  signal  for 
analysis is attached to a BNC input on this card. 

Views Offered 

The following displays are offered: 

1.

 

Jitter Display

 – from which information about the waveband in which the timing jitter is 

occurring can be deduced. 

Note: 

A maximum of two Jitter displays can be shown at the 

same time, showing data for the same Eye input. 

2.

 

Eye Diagram 

for the same input. 

Note: 

It is not possible to display the Eye Diagram for 

one Eye input at the same time as the Jitter Display for the other Eye input. 

A certain amount of information about the various traces is displayed on screen, particularly in 
Auto Measure mode (see Section M.5). Additional status information is to be found in the Status 
Overview and on the PHY Status Summary (see Section E.6). Note, however, that this data is not 
shown if the input associated with the Status tile is either not looking at the input that is selected 
on the Eye/Jitter card or if the associated analyzer is not set to work on an Eye input. Also the 
values  shown  in  the  Status  displays  for  parameters  that  are  determined  in  Auto  Measure  mode 
are only updated when the current selection of Views includes an Eye display and Auto Measure 
mode is selected. 

The same general steps are involved in working with these displays as are used with other Views 
(see Section E.1) except that changes of input are applied to the displays as a group. 

It  is  expected that the displays mainly used in  monitoring performance will  be the PHY Status 
Summary and the Eye Diagram (where available). The role of the Jitter Spectrum display is as an 
aid to engineers in tracking down sources of jitter with the aim of eliminating these.
