Ed Petruzzelli – DISH –
I like it very much. It is our first piece of ATSC 3.0 test equipment and I like what I see. The ReFeree 3 is very easy to set up and operate and I had it looking at ATSC-3.0 RF signals and STL parameters within minutes of connecting to the laptop. I am looking forward to bringing this unit in the field for live signal analysis. Very nice job!
