DPP / Separator technology

[brad1138]

Can someone point me to a PDF or something detailing how the frequencies are distributed on tuner 1 & 2 in a DPP w/separator install. I am having an argument with my boss, and am trying to find proof I am right. I believe it uses band stacking and that one side of the separator is 950-1450 Mhz and the other 1650-2250 Mhz. All I can find online is forum discussions that agree with me, but nothing I can point to like a Dish tech bulletin or anything.

Thanks,
Brad
