摘要:
An unknown RF power is converted to a voltage by a detector (11). The voltage is converted to a number by a digitiser (12). A separate and fixed RF power reference (14) drives a second detector (15), whose voltage output is also converted to a number by the digitiser (12). The RF detectors are thermally coupled. Temperature variations in the RF power to voltage characteristic of the detector (11) are corrected by measuring the RF power reference (14) via the detector (15).
摘要:
A map builder system is implemented in a topological management system in a computer system to enable generic interfacing of an application with a display map generation process. The topological management system tracks a topology of objects. The map builder system includes a map builder and a topology data repository that implements a schema. The schema comprises a series of tables containing updated topological data representing particular attributes and relationships of the objects to be depicted. The map builder interfaces the topological data within these tables with a management system application programmatic interface (API), which interfaces with applications. The map builder constructs a series of mappings from the data, and the management system API is capable of using these mappings to construct a topology representing the relevant objects. The user can view the topology from the management system API and can change the topological representation, if desired.
摘要:
Power sensors to measure both the radio frequency (RF) power transmitted by radio equipment under test, and the RF power received the radio equipment under test, are mounted in a separate assembly (2) remote from the main means of power measurement and generation (1). The RF power sensors and other components in the remote assembly (2) are interconnected so as to allow measurement of both received and transmitted RF power at the Rf connector or connectors of the radio equipment under test (4). The main assembly and the remote assembly are connected by a flexible link (3).
