The IFR Aeroflex Weinschel 8311-352-6-FN is a six-channel programmable attenuator delivering precise, independent attenuation control across DC to 6.0 GHz. Each channel operates with 103/1 dB steps and SMA/F connectors into 50 ohm nominal impedance. Maximum insertion loss is 6.00 dB with SWR not exceeding 1.55. The unit combines a front panel interface with standard communication support—GPIB (IEEE-488), Ethernet (10 BaseT), and RS-485—enabling both manual benchtop operation and integration into automated test systems. Cast aluminum housing with internal ribs optimizes thermal management. Rack-configurable with supplied ears.
