Benchtop Manual Attenuators (Enclosure)
Benchtop manual attenuators are a staple RF test bench piece of equipment. Simple to control and requires no AC power to operate. These online models have the RF connectors on the rear panel and the manual knobs on the front panel. For your specific application, please contact JFW for assistance or use our Inquiry Form.
Step Attenuator Design
The benchtop attenuator assemblies use step attenuators internally. The step attenuators are connected in series with each other. The attenuation setting of the assembly is the sum of the attenuation indicated by both knobs.
