Installation
Installing in a Video System
The instrument can operate almost anywhere in the distribution system. Refer to the following diagrams for serial digital
system inputs.
For monitoring the video bit stream
at the end of a link
If the instrument is placed at the end of a
link, this setup can be used.
1. Connect a cable to a serial signal source.
2. Terminate the loop-through on the SDI
connector you will use on the instrument.
3. Connect the cable from the serial source
output to the one of the SDI inputs on the
rear panel of the instrument.
NOTE. See the Speci fi cations and
Performance Veri fi cation manual on the
Product Documentation CD for maximum
allowed cable lengths.
For monitoring within an operating
link
If the instrument is installed to monitor
an operating link, the destination receiver
and the connecting cable serve as the
termination. This monitoring connection
checks the performance of the entire
path. The return loss of the instrument is
suf
fi ciently high that, in most cases, the
destination receiver sets the system return
loss.
4. Connect a cable to a serial signal source.
5. Connect the other end of that cable to
one of the SDI inputs on the rear panel
of the instrument.
6. Connect a cable from a serial receiver to
the SDI loop-through on the instrument.
