I use a Tek TDS220 at work, and I also have a Tek TDS 210 at home.

You're talking about aliasing problems.
I'm not sure what you mean. These scopes have a sample rate of 1 GS/s and
an analog bandwidth of 100 MHz (60 MHz for the TDS 210).

Aliasing should not occur with frequencies less than 500 MHz.
Since the bandwith limitation would attenuate such a signal to
virtually zero, I cannot see how you would be able to experience
aliasing problems.

Care to explain?

BTW, I'm really pleased with the performance of these scopes.
I think they have an unbeatable performance/price factor.
