*Answer:* We have two types of attenuators in our X-Series Analyzers. The mechanical attenuators are passive devices. The electronic attenuators are active devices. The primary attenuators in X-Series analyzers are mechanical, because mechanical attenuators are able to cover a wide frequency range, up to 26.5 or 50 GHz. For the low band path, X-Series also has an electronic attenuator. The advantage of the electronic attenuator is that it can switch faster than a mechanical attenuator.
