A New Lower Cost Solution for Programmable Attenuation!

Weinschel’s New 8331 Series Programmable Attenuator Units offer a lower cost solution for automated bench test and subsystem applications. Standard 8331 Series designs house and control various Weinschel Programmable Attenuator Models (3200-XE, 3400, 150T, and 4200 Series) via ethernet, USB 2.0 and Serial communications interfaces.

Most 8331 Series are multi-channel configurations where RF signal is routed through either the front or rear mounted Ports. This series can be configured for up to 12 independent channels of attenuation. Multiple programmable attenuators can be used in conjuction with other coaxial devices such as switches, power combiners, directional couplers, and filters creating various multichannel test configurations.
