But when we perform the classical sensitivity test with a modulated signal, do we get the AM or CW value?
Following the instructions I got a value of -104 dBm, i.e. 1.41 uV. Because I used the DA-121, the real value should be even better, far from 5 uV. And surely my R-390A is not as good as it could be .
