A New Streamlined Approach for Programmable Attenuation!

Weinschel’s Model 8320 Series Programmable Attenuator Units represent a new streamlined approach in programmable attenuation for bench test and subsystem applications. Standard 8320 Series designs house and control various Weinschel Programmable Attenuator Models (3200-XE, 3400, 150T, and 4200 Series) via front panel controls, ethernet, USB 2.0 and Serial communications interfaces. A GPIB (IEEE-488) interface is also available as an option.

The 8320 series are single or dual channel configurations housed in half rack enclosures. This series can be configured for front or rear connectors.
