Page 3: Cell Configuration
150 T Series SmartStep ® Programmable Attenuators BUILT-IN SMARTSTEP DRIVER CIRCUITRY: These SmartStep ® attenuators feature an internal microcontroller-based driver that provides a TTL-level digital interface for control of the attenuator relays. This card simplifies 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 Smartstep bus. -
Page 4: Installation
IM-275 INSTALLATION MOUNTING: Each Programmable Step Attenuator is supplied with two mounting screws (P/N MS35335-57). These screws will fit any of the mounting holes (4-40 UNC-2B x 0.22 MIN DP) located on either side of the attenuator. RF CABLE INSTALLATION: Care should be taken to prevent strain on the inter- connecting cables, since damage here may not always be apparent. - Page 5 150T Series SmartStep ® Programmable Attenuators PARALLEL MODE OPERATION: In the parallel mode of operation, the Smartstep attenuator accepts TTL-level parallel data on the D0-D7 input data lines. Each data line controls a separate attenuation cell, where a logic 1 input (TTL high) engages the attenuation cell, and a logic 0 input (TTL low) bypasses the cell, providing a through path.
