    The Tek SI 5010 can switch and route up to 16 high frequency input and/or ouput signals. It maintains a clean 50ohm environmentthrough the use of 50ohm reed relays. It is used in the TM5000 series frames.
    ====================================================
    The SI 5010 Scanner is a two-wide, TM 5000 plug-in capable of scanning and switching 16 different signal channels or a combination of signal channels, under program control. Optimum frequency response is 350 MHz. Of the 20 front-panel BNC connectors used for channel switching, 16 are connected internally to 16 R.F. reed relays and four are connected to common points. The common points act as output connectors to an external system. The 16 relays can be programmed to connect to the common points in various combinations. Three possible combinations are:
  • 4 groups of 4 channels
  • 2 groups of 8 channels
  • 1 group of 16 channels Other features are:
  • Fully Programmable
  • IEEE-488 1978 Compatible
  • 350-MHz Bandwidth in 4-Channel Configuration
  • External Handshake Lines
  • Built-in Time-of-Day and Pacing Clock
  • Command Buffer for Controller-Free Operation
