Figure 1. Combiner block diagram The module is designed for use in RF test systems to provide accurately calibrated signal routing, combining or splitting between up to three RF measurement modules and the test subject. The 3060 is ideally suited for use in conjunctioin with Aeroflex 3020 Series Digital RF Signal Generator and 3030 Series RF Digitizers. Together these modules enable development of compact, high performance and low cost modular test systems for RF transceiver and component testing. In addition to providing summing of signals the 3060 provides RF switching between ports A - B and B - C. These switch connections enable test system calibration without the need to disconnect the test subject. In this mode either the signal source or the signal analyzer can act as the calibration reference. Alternatively an accurate power meter can be connected to the 3rd input port to provide more accurate test system calibration. To maximize flexibility, each port is bi-directional thus allowing a wide variety of system configurations to be supported Electronic RF switching is used to ensure that minimal time delays are incurred when performing system calibration as well as providing high reliability for volume manufacturing. Calibration The 3060 is provided with on-board frequency response calibration data accurate to better than 0.2 dB. Calibration data can be addressed over the PCI bus and used to provide system calibration to the plane of the output connector. This minimizes test system uncertainty and thereby helps to improve manufacturing yield. The frequency response for each RF path is factory calibrated and stored within the module. Applications The 3060 is designed for use in radio test applications such as transceiver testing where the (Ó) port acts as a single port duplex connection point with one or two RF sources providing Rx stimulus input(s) and an RF signal analysis instrument connected to the third port to measure DUT Tx parameters.
