Problems solved by technology

[0002] Existing RF program-controlled attenuators are either fixed attenuation values ​​or mechanical attenuators with variable attenuation values ​​that require manual knob operation. It is very troublesome to adjust or fine-tune the RF network attenuation after the installation of the online network. line, replace the original attenuator with an attenuator with a suitable attenuation value, or manually adjust the knob to adjust to a suitable attenuation value

Abstract

The embodiment of the invention discloses an attenuator control circuit. The attenuator control circuit comprises a controller and at least one group of sub-circuits, each group of sub-circuits comprises an attenuator, a first measuring circuit and a second measuring circuit; in each group of sub-circuits, the first measuring circuit is used for measuring the first intensity of a signal input intothe attenuator; the second measuring circuit is used for measuring the second intensity of the signal output by the attenuator; and the controller is used for sending a control instruction to the attenuator based on the attenuation parameter and adjusting the attenuation value of the attenuator to a target attenuation value, receiving the first intensity and the second intensity, and determiningan actual attenuation value based on the first intensity and the second intensity; and the actual attenuation value is used for determining whether the attenuator meets an attenuation target or not.

Description

technical field [0001] The present application relates to communication technology, in particular to an attenuator control circuit. Background technique [0002] Existing RF program-controlled attenuators are either fixed attenuation values ​​or mechanical attenuators with variable attenuation values ​​that require manual knob operation. It is very troublesome to adjust or fine-tune the RF network attenuation after the installation of the online network. line, replace the original attenuator with an attenuator with an appropriate attenuation value, or manually adjust the knob to adjust to an appropriate attenuation value. Contents of the invention [0003] In order to solve related technical problems, an embodiment of the present application provides an attenuator control circuit. [0004] The technical scheme of the embodiment of the application is realized in this way: [0005] An embodiment of the present application provides an attenuator control circuit, including: ...
