Re: [Connectivity] Motorola 5100 vs. 5120 said by Nerdtalker:SB5100 • TI (Texas Instruments) chipset is more susceptible to noise related issues, especially in a 256QAM modulated plant Could you expound on that? Noise from what? Is there something I should be keeping it away from? And what's a "modulated plant"?
Incidentally, I note that I have firmware "SB5120-2.9.2.10-SCM03-NOSH," and I've seen references to it going back to last year. If it's still current, I guess they don't update it very often. |

Noise as in low SNR (Signal to Noise Ratio). It just isn't as good at handling excessive noise (below 33dB) when the downstream channel is using 256QAM for modulation as the SB5100's broadcom chipset is.
Plant is just a term for cable system.
