I would like to know the frequency allocation of the analog and digital channels being sent from the Head End? As an example: analog channels are sent on: B MHz to C MHz, Digital channels are sent on D MHz to E MHz.

How many channels are in the analog/digital blocks respectively?

Does anyone have a spectrum analyser capture of the CATV RF spectrum?

Curious why you would want to know that?

Couple of thoughts:
  • I imagine you could figure it out by checking the info pages on your set top box.
  • Wouldn't it be different depending on what city you are in?

I work for a company that designs TV tuner chips and I need to understand the RF input scenarios to properly specify tuner linearity and filter requirements.

That's interesting. Since they've been making tuner chips for years I would have thought a lot of that information would be standard and easily attainable and not specific to Rogers.

If you have a digital STB, you can see the QAM frequencies for the digital channels in the diagnostics page 20 of PVR (perhaps on page 5 of STB). For example, CP 24 is 477 MHz (for me). Rogers has most areas built out to 860 MHz. It would depend on your location somewhat. The channels for analogue and digital services are listed for each location on the Rogers website.
