It must be my old age setting in but I can't get my head on right. I have an AT1 attenuator I just finished assembling. My understanding of dB attenuation must be off. If I use an input of 1 volt, shouldn't I expect 0.1 volt out if I have selected 20 dB attenuation? Harlan NC3C Sent from my Verizon Wireless 4G LTE DROID
