33320G Agilent Step Attenuator
The 33320G is a 4 GHz step attenuator from Agilent. Attenuators are a type of radio frequency (RF) test equipment that’s useful during RF design. When an engineer needs to reduce (attenuate) the level of an electronic signal, he or she uses an attenuator. Attenuation can protect circuit stages from receiving signal levels that are too high. RF attenuators may be fixed, switched, or variable, depending on their capabilities and applications.
