Field Strength vs. reciever sensitivities
Field Strength vs. reciever sensitivities
(OP)
Hello all ,
I just got a brand spanking new Spec analyzer and I am new to the game ( just graded) I am curious as to the best way to compare my field strength readings to the RX sensitivies of various devices. All the sensitivies I see are in dBm or uV . my metre can give me numbers in dbm/m or dbuv/m ect. what is the relationship and how do I use these values? any help is much appreciated

RE: Field Strength vs. reciever sensitivities
What make and model spectrum analyzer do you have?

Google the antenna calibration factor or look up EMI/EMC companies and find antenna factors used for that type testing.

Pardon the delay, but I just saw this thread. I sifted through some miscellaneous equations I've accumulated over the years, and found this:
uV/m = 10^[(dBm - G + 20*logF + L +75)/20]
where
dBm = signal level at receiver input in dB with respect to 1 mW
G = receiving antenna gain in dBd
L = line loss
F = Frequency in MHz
