Description
Weinschel’s New 8310 Series SmartStep Attenuator Units
represent a new concept in programmable attenuation for
bench test and subsystem applications. Standard 8310
Series designs house and control various Weinschel
Programmable Attenuator Models (3200T, 150T, and 4200
Series) via front panel controls or standard communications
interfaces including GPIB (IEEE-488) and RS-232/RS-422
/RS485. The 8310 combines the features of the 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 pro-
grammable attenuators can be used inconjuction with other
coaxial devices such as switches, power combiners, direc-
tional couplers, and filters creating single or multichannel
subsystems.
MODEL 8310
SmartStepTM Programmable Attenuator
RS232\RS422/RS485
A New Concept in Programmable Attenuation!
Features
oProvides a flexible, easy to program, low cost solution
for your bench test/calibration setups and subsystem
applications.
oMulti-Channel attenuation paths (up to 4 input/outputs)
oRelative vs. Nominal attenuation step function.
oWide choice of Frequency & Attenuation Ranges.
- dc to 1, 2, 3, 18 & 26.5 GHz
- up to 127 dB
- Solid-State (GaAs FET *& PIN)
- Relay Switched
- 75 ΩConfigurations
oHigh Accuracy & Repeatability.
oDesigned to interface with Weinschel’s new line of
SmartStep programmable attenuators and other
electromechanical devices
oDesigned to interface with industry standard
communication interfaces:
- GPIB/IEEE-488 (HS-488 ready)
- RS-232, RS-422, RS-485
oRack Configureable: The Model 8310 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.
Applications
Applications for the 8310 Series range from providing
control of a single SmartStep Attenuator in a bench test/lab
environment using a PC and a terminal emulator, to com-
plex system applications where the 8310 Series is
employed to control many devices to create custom/semi-
custom subsystems to reduce overall design cost.
Weinschel can provide a variety of custom designed driver
interfaces for various devices, such as RF switches, relays,
pin attenuators, motorized step attenuators, displays, and
other devices, as well as complete subsystem design and
integration services. Contact us with your specialized
needs.
