    The Wideband AC Module (Option 5700A-03) can be installed in the Product. The module needs to be calibrated for both gain and flatness. The gain should be calibrated when the 5730A main output functions undergo their routine calibration. Since frequency flatness is determined by stable parameters (for example, circuit geometry and dielectric constants), the flatness of the Wideband AC Module has excellent long-term stability.
