With a +13dBm carrier this corresponds to a noise voltage of 100pV/rtHz across a 50 ohm resistor or a noise current of 2pA/rtHz flowing through it. Hi Bruce, but isn't the thermal noise at room temp about 130pV/rtHz or so for a 1 ohm source resistor by itself? Wouldn't the source resistance's thermal noise be the limiting factor? bye, Said ************************************** See what's free at http://www.aol.com. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
