Zo doesn't matter for these purposes. dBm works just as well for 75 ohm systems.

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. Assuming a 50 ohm system, of course. -- john, KE5FX Miles Design LLC
