As compared to the original configuration, the ALC level is 10 dB higher while the attenuator
reduces the LO feedthrough (and the RF output of the signal generator) by 10 dB. Using the
attenuated configuration, the detector is exposed to a +2 dBm desired signal versus the
−
15 dBm undesired LO feedthrough. This 17 dB difference between desired and undesired
energy results in a maximum 0.1 dB shift in the signal generator’s RF output level.
