author : Mr. Alberto Simao _ Macau S.A.R.

I have done the following Setup: Insat4B at Frequency of 3 950 with 900 cm Vertex antenna.

 
The output of Norsat LNB was divided by 4 and i have applied one Out to R&S another to Tandberg TT1260 and another
to Promax. The Tandberg ASI-1 Output I have connected to R&S External ASI Input for measuring and view the video signal
from Sakshi TV.This Tandberg Receiver have a Low Sy facility,so i use the ASI output for monitoring in the R&S.
Is including a small video clip for reference taking by camera from R&S screen.
