A New Concept in Programmable Attenuation!

Click here to get the Model 8310 Data Sheet...
Aeroflex / Weinschel’s 8310 & 8311 Series SmartStep® Attenuator Units represent a new concept in programmable attenuation for bench test and subsystem applications. Standard 8310 & 8311 Series designs house and control various Aeroflex / Weinschel Programmable Attenuator Models (3200T, 3400T, 150T, and 4200 Series) via front panel controls or standard communications interfaces including GPIB (IEEE-488) and RS-232/RS-422 /RS485. Ethernet optional.


The NEW 8311 series is a full 19" rack configuration that allows for additional multi-channel attenuation paths (up to 6 input/outputs standard) as well as additional space for custom designs such as complex attenuation/switching matrices, celluar/pcs fading simulation and cable modem testing. This series offers all the same features as its 8310 Series counter parts.

The 8310 & 8311 combine the features of the Aeroflex / Weinschel 8210A Device Controller with a front panel user interface to form a flexible, easy to use solution.

Most 8310 Series are single channel configurations where RF signal is routed through either the front or rear mounted Ports A & B but can be configured for up to four channels of attenuation, RF switching, or other functions. Multiple programmable attenuators can be used inconjuction with other coaxial devices such as switches, power combiners, directional couplers, and filters creating single or multichannel subsystems.

  • Provides a flexible, easy to program, low cost solution for your bench
    test/calibration setups and subsystem applications.
  • Multi-Channel attenuation paths (up to 6 input/outputs)
  • Relative vs. Nominal attenuation step function.
  • Wide choice of Frequency & Attenuation Ranges.
    • 75 ohm Configurations with BNC or Type Connectors
    • dc to 1, 2, 3, 18 & 26.5 GHz - up to 127 dB
    • Solid-State (GaAs FET & PIN)
    • Relay Switched
  • High Accuracy & Repeatability.
  • Designed to interface with Aeroflex / Weinschel’s new line of SmartStep programmable
    attenuators and other electromechanical devices
  • Designed to interface with industry standard communication interfaces:
    • GPIB/IEEE-488 (HS-488 ready)
    • RS-232, RS-422, RS-485
  • Rack Configureable: The Model 8310 & 8311 can be rack mounted either as a single unit using Rack Mounting Kit (P/N 193-8033) or two Model 8310's can be mounted together using Rack Mounting Kit (P/N 193-8033-1). Using these kits allow the Model 8310 to be easily mounted into any rack or cabinet that is designed per EIA RS-310 or MIL-STD-189.
