Hi,

 

I changed my subscription to X1 and received a SAM SX022ANM (XG2 correct?) box. In preparation for this change I purchased a PPC EVO 1-5 U/U Lossless Splitter because I plan to add additional TVs. Before installing the EVO my wiring setup was:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

With this setup my X1 Box was reporting the following signal readings:

 

Down SNR: 40 dB

Up Power: 37 dB

 

Then I installed the PPC EVO with the following setup:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Now my X1 box is reporting the following signal readings:

 

Down SNR: 40 dB

Up Power: 34 dB

 

I'm kind of puzzled since the EVO is supposed to be lossless (Forward/Reverse neutral gains). How come I have better signal readings with the lossy Extreme splitter?

 

My X1 box is somewhat sluggish. Usable but not butter smooth running OnDemand and navigating menus/guide.

 

Any comments? Ideas?

With upstream, if the number is higher it means the X1 box is working harder to return signal to Comcast. The lower number is better.

In regards to upstream signal the lower the number the better...

What's the downstream?

Hmmm I have to admit that I might be a bit lost here. Are you sure the lower the Upstream Power the better?

 

Andrew (from Comcast) replied in an older thread the following. Quote:

 

"Downstream received should be between 8 and -8
Downstream SNR should be over 35
Upstream Power should be between 35 and 51"

As Rick said
Upstream lower is better and downstream higher is better.
Splitters cause upstream to up and downstream to go down. Since you removed a splitter, upstream goes down and downstream goes up by whatever value of splitter was present.

Got it thanks!

 

In regards to the X1 box being a little sluggish. Any comments? It is usable but not snappy and smooth...
