Programmable AttenuatorSee 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.
Available in single and multi-channel configurations with most Programmable types.
The MN63A/65A/72A/64B provide GPIB as a standard feature and are suitable for automatic measuring system components used in R & D, inspection, or production. The 50 ohm models are available in four different frequency ranges, which can be selected to match the application for maximum economy. The attenuation calibration value is stored in the internal memory and can be uploaded to the system controller for checking against measured values, permitting a significant increase in system accuracy. A relative setting function is also provided, which allows measurement to be referenced to any arbitrary level. Rotary encoders are standard, allowing simple, smooth setting under manual control.
Keysight Technologies Inc.
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.
