That is why I asked what the Po was. Where did the 177 come from? L(f) is single sided. This is not my first "rodeo" in these matters. 73 - Mike

If it were dBm/Hz, then kT would be the limit. But in dBc/Hz terms, the limit is 177 + the DUT's output power in dBm. Assuming a 50 ohm system, of course. -- john, KE5FX Miles Design LLC > -----Original Message----- > From: time-nuts [mailto:[email protected]] On Behalf Of Mike > Feher > Sent: Thursday, August 11, 2016 12:51 PM > To: 'Discussion of precise time and frequency measurement'; > [email protected]; [email protected] > Cc: [email protected] > Subject: Re: [time-nuts] State of the art of crystal oscillator > measurements > > kT is indeed relevant for a physical implementation. - Mike > > Mike B.
