Description

Variable/step attenuators can be used to adjust the power signal level continuously or by step within certain

frequency range, they can also be used to adjust the test system's power level as inset attenuators, it is small

with high accuracy and high stability etc.

Programmable attenuators are generally used to control the power level of microwave signals with

TTL\CMOS driver control manner and designed for use in automatic test equipment (ATE) systems operating

in the dc to 18 GHz frequency range.

In this section, you can find the Variable/step/programmable attenuators with individual data sheets

containing product description, specifications and outline drawings by a quick reference guide.

Model SHX371 Serial DC-18GHz Programmable/Mechanical Attenuators

DESCRIPTION

With excellent electronical and mechanical performance, SHX-371 serial programmable/mechanical attenuators are used

to high frequency attenuation system, they are feature wideband frequency range, low VSWR, long life cycle, high

repeatability and stability etc.

Through being connected with the special computer’s interface circuit or external instruments (or circuit panels) produced

by Shanghai Huaxiang Co.,Ltd, SHX-371 serial programmable/manual attenuator produced by Huaxiang can realize the

attenuation of radio frequency power ,and come through the auto control or manual transition in programmable/manual. The

products are widely used in scientific research, aviation military, broadcast, weather service and medical treatment where

attenuation in high frequency is in use. The main parameters have been close to or reached the one of the world’s famous

company. The serial productions contain two controlling manners, the programmable one and the manual one.
