Hi In addition to the stuff already mentioned, there's one more reason: RFI
If you want to run around with a 10 MHz square wave with 1 ns rise time edges, it's going to have energy all over the place. To keep the rise time you will get well into the GHz. That may (as in probably will) interfere with a lot of RF measurements.

Why is 10MHz output of many sources or distribution amps in the form of a sinewave? Is it something to do with signal reflections or ease of isolation? Since zero crossing detectors are susceptible to noise wouldn't a fast TTL square wave be more appropriate for signal distribution within a equipment rack? -- http://www.fastmail.fm - Send your email first class _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
