Multi-channel satellite universal measurement and control link conditioning device

Abstract

The invention discloses a multi-channel satellite universal measurement and control link conditioning device, comprising a first link conditioning mechanism and a second link conditioning mechanism, wherein the second link conditioning mechanism is a supplement to the first link conditioning mechanism; the first link conditioning mechanism comprises seven couplers, three circulators, three power dividers, eight programmable attenuators and two switches, all couplers are connected with the switches, the couplers and the circulators are both connected with the power dividers, and the programmable attenuators are connected with the couplers; and the second link conditioning mechanism comprises three couplers, two circulators, one power divider, three programmable attenuators and one switch, the couplers and the ccirculators are both connected with the power divider, the programmable attenuators are connected with the couplers, and the couplers are connected with the switch. The multi-channel satellite universal measurement and control link conditioning device disclosed by the invention is integrally designed, and has a large-capacity link conditioning ability, complete compatibility and a flexible adjustable configuration function.

Description

technical field [0001] The invention relates to a conditioning device, in particular to a multi-channel satellite universal measurement and control link conditioning device. Background technique [0002] With the development of my country's satellite industry in recent years, satellite testing tasks have been increasing, and the number and functional requirements of satellite ground testing equipment have continued to increase. However, the existing equipment lacks versatility and reusability, and there is a huge waste. Currently, the commonly used link conditioning methods are patchwork of separate devices or customized according to certain requirements, which are often difficult to satisfy complex transmission processes and more signal conditioning processes. In addition to the need for personnel with professional knowledge and ability to build, due to the lack of versatility, the waste of resources is also very serious.
