SmartStep® Plug-n-Go Attenuators

Aeroflex / Weinschel's approach also includes a new generation of intelligent programmable step attenuators with a built-in digital interface. These models are designed to simplify the control and integration of these devices into subsystem and bench applications.

The SmartStep attenuators feature a microcontroller-based driver that provides a TTL-level digital interface for control of the attenuator relays or solid-state circuitry. This new feature simplifies operation and interfacing requirements, while at the same time providing for greatly enhanced flexibility over past designs.

These SmartStep Devices contain non-volatile configuration memory used to hold a wide variety of attenuator and driver-dependent parameters, including serial number, attenuator cell dB values, mechanical relay or solid-State (GaAs FET & PIN) configurations, and switching requirements which are all accessible via the Device Interface Bus (DIB).
