Level Accuracy and Electronic Level Settings of SMIQ

Most signal generators are equipped with a mechanical attenuator. Those attenuators are exposed to mechanical stress due to mechanical switching. To avoid mechanical stress on the attenuator the SMIQ is additionally equipped with two electronic attenuator functions that provide level settings without degrading attenuator performance and without exposing the attenuator to mechanical stress. These functions are especially useful in production and production testing where frequent level setting is necessary.
