The SI5010 Programmable Scanner provides the capability of switching and routing up to 16 high-frequency input and/or output signals. It maintains a clean 50 Ohm environment through the use of 50 Ohm coaxial reed relays. Equipped with 20 BNC connectors, 16 channels and four commons. TTL compatible. The SI5010 has a built-in command buffer capable of storing up to 300 GPIB system commands and executing them in sequence. It is paced by the on-board time-of-day and pacing clock or by signals from the system controller, thus freeing the controller to direct activity elsewhere in the system. Features Software configurable as: 1 group of 16 channels, 2 groups of 8 channels and 4 groups of 4 channels 350 MHz bandwidth in 4-Channel Configuration External Handshake Lines Built-In Time-of-Day and Pacing Clock Command Buffer for Controller Free Operation
