Programmable Attenuators
Models 8310 & 8311
Programmable Attenuator Units
Now Available with Ethernet Control!
Description
Aeroflex / Weinschel’s 8310 and 8311Series Programmable
Attenuator Units represent a new concept in programmable
attenuation for bench test and subsystem applications.
Standard 8310 Series designs house and control various
Aeroflex / Weinschel Programmable Attenuator Models
(3200T, 150T, and 4200 Series) via front panel controls or
standard communications interfaces including GPIB (IEEE-
488), Ethernet and RS-232/RS-422/RS-485. This series
combines 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, amplification or other functions.
Multiple programmable attenuators can be used inconjuc-
tion with other coaxial devices such as switches, power
combiners, directional couplers, and filters creating single or
multichannel subsystems.

o
Designed to interface with Aeroflex / Weinschel’s line
of digitally controlled programmable attenuators and
other electromechanical devices.
o
Designed to interface with industry standard
communication interfaces:
- GPIB/IEEE-488 (HS-488 ready)
- RS-232, RS-422, RS-485
- New Models with Ethernet Control (10 BaseT)
o
Rack Configurable:
Model 8310 Series can be rack
mounted either as a single unit using Rack Mounting Kit
(P/N 193-8033-1) or two Model 8310's can be mounted
together using Rack Mounting Kit (P/N 193-8033-2).
These kits fit into any rack or cabinet that is designed
per EIA RS-310 or MIL-STD-189. Model 8311 Series
are equipted with rack ears.

Applications
Applications for the 8310 and 8311 Series range from pro-
viding control of a single Programmable Attenuator in a
bench test/lab environment using a PC and a terminal emu-
lator, to complex system applications where the 8310/8311
Series are employed to control many devices to create cus-
tom/ semi-custom subsystems to reduce overall design
cost. Aeroflex / Weinschel can provide a variety of custom
designed driver interfaces for various devices, such as RF
switches, relays, pin attenuators, motorized step attenua-
tors, displays, and other devices, as well as complete
subsystem design and integration services. Contact us with
your specialized needs.

1. GPIB/IEEE-488 model allows user-selectable addresses, Not included with Models with ethernet option.
2. RS-232 can be used with standard PC serial port for short and medium distances (up to approximately 50 ft).
3. RS-422, designed for very long distance communications (4000 ft) and & optimized as a single node protocol, typically with one device connected to a
single port.
4. RS-485, designed for very long distance communications (4000 ft) & optimized for multi-drop connections that can used to create a low cost network.
5. Refer to Individual data sheet for detailed specifications on internal programmables.
