Embodiment Construction

[0018] The present invention is specifically described below in conjunction with accompanying drawing:

[0019] combine figure 1 , a manual and program-controlled dual-purpose step attenuator, including a program-controlled mechanism and a manual mechanism.

[0020] Among them, the program-controlled mechanism includes a relay 1 and an attenuation component. The relay 1 has a magnetic holding function. The circuit control board 2 is connected to the relay 1. The center of the relay 1 is provided with an iron core 3 passing through the relay. The circuit control board 2 can control the iron The core 3 moves up and down in the relay, the lower end of the iron core 3 is fixedly connected with two push rods 4 , and the lower end of the push rod 4 is connected with a transmission line 5 . The attenuation component includes an upper transmission substrate 6 and a lower attenuation sheet 7 , and the transmission line 5 is located between the transmission substrate 6 and the attenuat...

Abstract

The invention provides a manual and program-controlled dual-purpose step attenuator, which includes a program-controlled mechanism and a manual mechanism. The program-controlled mechanism includes a relay and an attenuation component. The center of the relay is provided with an iron core passing through the relay, and the iron core is up and down in the relay. Moving, the lower end of the iron core is fixedly connected with two push rods, the lower end of the push rod is connected with a transmission line, the attenuation assembly includes an upper transmission substrate and a lower attenuation sheet, and the transmission line is located between the transmission substrate and the attenuation sheet. The manual mechanism includes a knob and a sleeve. The knob is set on the upper part of the sleeve. A sliding rod is arranged inside the sleeve. The upper part of the sliding rod is connected with the knob. The first spring is connected, the first spring is set on the sliding rod, the two shrapnels extend out of the sleeve laterally, the upper end of the iron core extends laterally into the space between the two shrapnels, and the lower part of the sliding rod is connected with the second spring , the lower end of the second spring is connected with the sleeve.

Description

technical field [0001] The invention relates to the field of attenuators, in particular to a manual and program-controlled dual-purpose step attenuator. Background technique [0002] At present, step attenuators are generally divided into two types: manual step attenuator and program-controlled step attenuator. The manual step attenuator adopts the method of converting the action of the button or knob into the contact and disconnection of the transmission reed and various attenuation sheets, and realizes the attenuation of the signal through the combination of several attenuation sheets. This type of attenuator works without electricity and is easy to carry. It is widely used for on-site debugging, but it cannot be used in automatic test equipment. [0003] Program-controlled step attenuators are divided into electromechanical program-controlled step attenuators and electronically controlled step attenuators, which are widely used in automatic test equipment such as signal ...
