Programmable Attenuator

See Programmable Attenuator Products

An attenuator is an electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than 1.

Keysight attenuators find use in a wide variety of applications for signal conditioning and level control, such as: Reducing signal levels, matching impedances of sources and loads, and measuring the gain or loss of a two-port device. They offer the best reliability and repeatability in the industry.
