Remember that L(f) is expressed in dBc/Hz, not dBm/Hz. 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 - transistor large signal NF in dB . 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.
