Aeroflex / Weinschel’s Labview based Attenuator Control
Center Software (ACCS) can be used in conjunction with
the operation of the this series of programmable attenuator
units and allows the user to setup, control and perform test
and measurements over standard communication interfaces such as RS-232, USB, Ethernet or optional IEEE-488.
Model
8320
Description
Features
o Provides a flexible, easy to program, low cost solution
for your bench test/calibration setups and subsystem
applications.
o Front panel local control and display make it ideal for
lab and manual test environments.
o Relative vs. Nominal attenuation step function.
o Multi-Channel attenuation paths (up to 2 channels for
8320 & up to 12 channels for 8321)
o Various Configurations, up to 40 GHz:
- dc to 3, 6, 18, 26.5 & 40 GHz
- Attenuation ranges up to 127 dB
- 50 & 75 Ω Configurations
- Solid-State & Electro-Mechanical types
- New MMIC switched digital attenuators
- Relay Switched
Aeroflex / Weinschel’s Model 8320 and 8321 Series
Programmable Attenuator Units represent a new streamlined approach in programmable attenuation for bench test
and subsystem applications. Standard 8320 and 8321
Series designs house and control various Aeroflex /
Weinschel Programmable Attenuator Models (3200-XE,
3400, 150T, and 4200 Series) via front panel controls,
ethernet, USB and Serial communications interfaces. A
GPIB (IEEE-488) interface is also available as an option.
The 8320 series are single or dual channel configurations
housed in half rack enclosures. The 8321 series are multichannel configurations housed in 19 inch enclosures and
can be configured for up to 12 attenuation channels. Both
series can be configured for front or rear and through (front
to rear) is only available for 8321 Series.
Aeroflex / Weinschel also provides custom subsystems
where a variety of test configurations can be incorporated
within a single unit. Contact us with your specialized needs.

Applications
Applications for the 8320 and 8321 Series range from
providing control of a single Programmable Attenuator in a
bench test/lab environment, to complex system applications
where the 8320/8321 Series are employed inconjuction with
many devices to create custom subsystems to reduce overall design cost. Multiple programmable attenuators can be
used in conjuction with other coaxial devices such as
switches, power combiners, directional couplers, and filters
to create various multi-channel test configurations.
