Model SPA-71 Serial
Programmable/Mechanical Attenuators
DESCRIPTION

With excellent electronical and mechanical performance, SPA-71 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, SPA-71 serial programmable/manual attenuator produced 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.
