Re: -30dB pad
maybe some data from INTERNET will help you,
the following data are from the R&S, Boonton and Yokogawa.
Max RF input =
R&S Model FMA/FMB= 30 dBm
Boonton Model 8201 = 1W (7V RMS, 30 dBm)
Yokogawa Model VN7100 = 30 dBm(Full Scale Range)
Overload protection=
R&S FMA/FMB = 5W(15V RMS) = 37 dBm
Yokogawa Model VN7100 = (ADC overload) Full scale range + 10dB (typical) ~ 40 dBm
Max.peak Voltage=
R&S Model FMA/FMB = 25V (including DC)
Boonton Model 8201 = 40 VDC, 35VAC, 25 W for a source SWR<4
so, The spec say that the max input is 30 dBm, that usually there is protection
for overload at about 37-40 dBm and the max peak voltage is about 25 V- 40 V(AC or
DC)
so:
the peak power will be as much as 12 dB higher than the average power
is plain BS, BS....BS.....US (New England) BS.
