SMARTSTEP SUBSYSTEM DESIGN &
APPLICATION EXAMPLES |
|
Applications for the SmartStep Components & Subsystems range from control of a single SmartStep Attenuator in a bench test/lab environment using a PC and a terminal emulator, to complex system applications where an 8210A style interface is employed to control many devices to create custom and 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, displays and other devices, as well as complete subsystem design and integration services. This is the ideal solution for creating multi-path subsystems for use in specialized wireless communication test applications for Cellular, PCS, Modem, and CATV equipment and systems.
