  • Page 7: Introduction

    Introduction For flexible configuration of an EMC test facility and fully-automated testing, the ETS- Lindgren EMCenter™ Modular RF Platform provides space for up to seven plug-in cards in a 3U, 19-inch rack mount enclosure. The EMCenter can also be used as a desktop unit. The slots can contain a user-defined combination of these ETS-Lindgren cards: EMSwitch™, EMPower™, EMGen™, EMControl™, and EMSense™.
  • Page 8 7-Slot and 2-Slot The 7-slot and 2-slot systems are both 3U high and are standard delivered as a desktop model. They fit within a 19” rack mount enclosure when using the 19” brackets that are supplied. The main difference between these two models is the amount of slots. The 7-slot has nine slots and the 2-slot Lite has four.
  • Page 9 Two communication ports are located at the middle of the back panel:  One (Holaday compatible) serial port with settings: 9600,7,Odd,1  One USB-B connector. The interlock connector and a push button to start the LASER are located at the top of the back panel.
