I'm not entirely sure what style of AM detector you're talking about, but I see no reason why you'd need to also use a transient or envelope simulation to measure this.

Thank you for the reply.
Voltage Responsivity= output volatge(baseband)/input power(RF).
The detector is a kind of doubler detector as shown in below figure.
Btw, when I use hb, there is always a error that "fund frequency 20GHz does not divide evenly into the stimulus frequency 'ammodfreq' 80MHz"
I don't understand this error.
