ACCESSORIES

CELL CONFIGURATIONS:

SmartStep Interface: The Model 8210A SmartStep

Interface provides a flexible, low cost solution for the oper-

ation of programmable step attenuators and other

electromechanical devices under computer control.

Designed to interface to Weinschel's new line of SmartStep

programmable attenuators, the 8210A represents a new

concept in device control applications for bench test and

subsystem designs. The 8210A provides a high-level inter-

face from various industry standard communications

interfaces, including IEEE-488 and RS232/RS422/RS485,

to the SmartStep's serial Driver Interface Bus.
