I would agree that a simple tester that only looks for RF won't have any problems. Where you will have a problem is with the meters that do actual signal level measurements. They must be designed and calibrated for, in the case of CATV, QAM as well as analog and you need that now. For off-air it will be 8VSB. Some meters will handle both.
In a short while most CATV systems will be eliminating the analog channels simply because they are bandwidth hogs. They can put 10 digital channels or 2 HD channels in the 6 Mhz bandwidth of an analog channel.
This change has nothing to do with the over-the-air digital conversion now rescheduled for April.

Hal,
So, if I now understand correctly, it should be expected that a lower cost signal meter like the Holland ST-4000D that now reads 'off air' channels 2-69 would not continue to have this function after the change to
digital broadcast, but should still work for the actual
digital CATV signals from Comcast, my local cable service provider? If so, I think I can live with that.
