This Anritsu Calibration Kit Male, DC to 8GHz kit has been designed to provide superior measurement results when used with precision instruments. It is designed for use in both field and lab environments. It is a high precision component and should be handled with proper care. Excessive shock, torque, or power should be avoided to prevent permanent damage. Open and Short Phase and DC Resistance specifications are typical. Phase is measured as a deviation from the model defined by offset length and inductance or capacitance.
