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. TKX

No, it's going to be useless. It's an analog meter and it's going to give erroneous readings with digital signals. Doesn't matter if it's off-air or CATV.

Well that stinks... that's just what I was hoping wouldn't happen. So, it appears I am right back where I started.

They probably won't be doing that in anything close to a short while, and the reason is that they still have a significant number of customers without converters. Until the CATV systems have a low-cost set top box option (something that costs them $50 to buy instead of $250), they aren't going to eliminate the analog channels. Comcast has been battling the FCC over their requirement that new set top boxes support CableCard, which significantly increases the cost.

Comcast is already doing it--see my post above. Anything above analog basic (Chs. 2-31) will be snow unless you have a box (and, of course, the subscription). Vancouver Comcast customers had to get their boxes by March 18, the rest of the Portland area is to follow this spring. Comcast will be providing two digital boxes to every customer who doesn't already have one.

They haven't gotten rid of analog basic (I assume that's the limited basic tier), though. If there's a cable company that's gone completely digital, I've yet to hear about it.

Yes, but it is certainly close to "eliminating analog channels, freeing up bandwidth for digital use" (approx. quote). The analog basic customters are already a small portion of Comcast's customers and will likely shrink even further, as digital basic is now offered for the same price. One bit I read quoted 2010 as Comcast's analog cut-off. If the entice people over to digital with the price, they may be able to do it before then.

Well, if that was the approx quote then Comcast started doing that about 4 years ago when they took the TV guide channel off analog.
There's a portion of customers who subscribe to limited basic. Those are the ones that Comcast will find it a challenge to get to switch to digital.

Comcast has a whole lot of "extended basic" customers and they are the ones who will get a satellite unless Comcast duplicates the "4 box" deal.
