Hi,
I have a question regarding a CATV tester I have that looks for signal on channel 3 to verify an active line.
I'm wondering how likely it is that this tester will still continue to work as designed when the switch to digital TV actually takes place this June.
Will any of the traditional RF type CATV signal meters or analyzers in use now continue to function as intended after the change to digital takes place or must they be replaced?

If not, what type or brand of meter would you recommend for analyzing the new digital CATV and broadcast signals?

Thanks
