It provides a free-run frequency accuracy of within ±1.6 x 10-8 over a lifetime, without any external reference such as global positioning system. This development will optimize applications that require the highest precision. The self-calibrating OCXO will compensate for aging effects that normally require re-calibration of the oscillator after it has been installed in the customer's system. The CFPO-SC1 provides good frequency stability versus all ambient conditions at a low cost, combined with high reliability and power consumption as low as 3.0 W in steady state. The standard six-pin metal CFPO-SC1 package is a hermetically sealed component. Size: 67.0 x 60.0 x 40.0 mm.

These calibration standards are for dual high frequency probes that include the initial in- troduction for the GSGSG probe configurations with pitch between 100 to 250 mm. These new standards form an integral part of the on-wafer probing offerings that enable the performance of multiport linear devices and circuits to be measured under a desired mode of operation, thereby reducing modeling and design cycle time. To achieve this goal, these standards are used to calibrate commercially available mixed mode network analyzers such as the E5071B Agilent ENA series network analyzer to 8.5 GHz or the N1957A Agilent Physical Layer Test System to 50 GHz.
