I seem to have missed the part where it's explained why anyone cares about the harmonic content of their 10 MHz source...? Don't worry about it, it's pretty much irrelevant. Harmonic filters can only hurt phase stability. > My noise floor was about -80 dBm (~ -90 dBc). I saw nothing else > above this floor from DC to 150 MHz except for 60 Hz (at -83 > dBc). Surprisingly, the power line harmonics were all below the noise floor. Or they were cancelled by running the TBolt and spectrum analyzer from the same AC circuit. That's tripped me up before. -- john, KE5FX www.miles.io _______________________________________________ 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.
