Description

This line of intelligent programmable step attenuators with a

built-in digital interface are designed to simplify the control

and integration of these devices into subsystem and bench

applications. This series of Programmable Step Attenuators

is designed for use in automatic test equipment and OEM

systems operating in the dc to 3 GHz frequency range.

These models are available in many standard attenuation

ranges and cell configurations. Each cell contains a double-

pole, double-throw relay that provides a minimum loss or

attenuated path for the RF signal.

Programmable Attenuator/Switch Controller: The Model

8210A Programmable Attenuator/Switch Controller provides

a flexible, low cost solution for the operation of programma-

ble step attenuators and other electromechanical devices

under computer control. Designed to interface to Aeroflex /

Weinschel's intelligent programmable attenuators, the

8210A represents a new concept in device control

applications for bench test and subsystem designs. The

8210A provides a high-level interface from various industry

standard communications interfaces, including IEEE-488

and RS232/RS422/RS485, to the programmable

attenuator’s serial Driver Interface Bus.

Pullup current

These programmable attenuators feature an internal micro-

controller-based driver that provides a TTL-level digital

interface for control of the attenuator relays. This card sim-

plifies operation and interfacing requirements, while at the

same time providing for greatly enhanced flexibility over

past designs. User-selectable modes of operation include

both parallel and serial bus. The parallel mode provides a

simple, one-bit per relay on/off control with internal pullups

for use primarily in single attenuator applications. This mode

allows the attenuator to be controlled via a variety of meth-

ods, such as a TTL-level digital output port, or mechanical

toggle switches. The device bus provides a two-wire serial

bus structure and protocol for connecting a number of

devices to a single host control interface, suitable for use in

larger system and sub-system applications. The digital

interface contains non-volatile configuration memory that is

used to hold a wide variety of attenuator and driver-depen-

dent parameters, including serial number, attenuator cell dB

values, relay configurations, and switching requirements,

which are all accessible via the digital interface.

TEMPERATURE RANGE (Operating): -20°C to +70°C

TEST DATA: Test data is available at additional cost.

CONNECTORS: SMA female connectors per MIL-STD-348

interface dimensions - mate nondestructively with

MIL-C-39012 connectors.

INTERFACE CONNECTOR: 14 pin .025 square post

header on .1 center. Mates with Amp connector 746285-2 or

equivalent.

CONSTRUCTION:

Connectors:

Aluminum

Stainless steel body and beryllium

copper contacts.

In either operational mode, the microcontroller enters an

idle condition during periods of inactivity, turning off all

on-board clocks, reducing EMI concerns, and lowering

power consumption. On-board regulation for the digital

circuitry allows the attenuator to operate from a single input

supply voltage.
