Fixed Attenuators and Variable Attenuators

Choose from a variety of fixed attenuators and variable attenuators for rent, lease, or purchase from leading manufacturers of RF and microwave test accessories, at TRS-RenTelco.

Reduce the amplitude of signals without noticeably interfering with its waveform and simplify test setups, to get the best possible measurement outcomes. Available with equipment finance plans and around-the-clock customer support.

What Are Attenuators?

An attenuator is an electronic device that decreases the power of a signal without substantially distorting its waveform. Attenuators are typically passive devices that are made from simple voltage divider networks.

Fixed Attenuator

The fixed attenuator decreases the signal by a set amount. It is can be used to lower voltage, dissipate power, source, load matching and protect the input circuitry of test equipment from overload, which would cause signal distortion, and to improve impedance matching.

Variable Attenuator

The variable attenuator allows a manual fixed adjustment of the signal through a range of fixed steps. The variable attenuator can be used for determining sensitivity in a receiver.

Applications of Attenuators

Our range of Keysight and Narda attenuators are RF and microwave test accessories that you can use in a wide variety of applications for signal conditioning and level control. These include decreasing signal levels, matching impedances of sources and loads, and measuring the gain or loss of two-port devices.
