To generate the example output eye diagram shown, the PC and the spectrum analyzer are not
required. These items are used for other elements of the test procedure.
Bit Error Rate Test Set with the following:
DC Power Supply
Spectrum Analyzer with minimum 3 GHz
bandwidth
Six (6) each UTIFlex coaxial cables
Test Equipment Settings
The example eye diagram shown is for a 1.4835 Gb/s HD SDI signal. Similar eye diagrams can
be obtained at 2.97 Gb/s and at 270 Mb/s by changing the bit rate setting on the signal generator.

Equipment Name
Any valid SMPTE data rate
supported by the LMH0346SQ
SDI reclocker can be used.
These rates are 270 Mb/s,
1.485 Gb/s, 1.4835 Gb/s,
2.967 Gb/s, and 2.97 Gb/s
This is a standard
pseudorandom pattern 127
bits long. Other
pseudorandom patterns can
be used as well as live SDI
video patterns (which are not,
in general, pseudorandom) or
the SMPTE pathological data
sequences.
