  • Page 2: Safety Precautions

    Safety Precautions The following safety precautions should be observed before using this product and any associated instrumentation. The WARNING heading in a manual explains dangers that might result in personal injury or death. Always read the associated information very carefully before performing the indicated procedure. The CAUTION heading in a manual explains hazards that could damage the instrument.

  • Page 3: Installation

    Introduction The mb-Technologies HVM high voltage switch series is a computer-controlled switching matrix designed for semiconductor characterization applications. It connects a number of instruments - connected to the matrix inputs - to test structures connected to the matrix outputs. The connection is done using a high voltage relay matrix with guarded contacts. Optionally, triple-switch FORCE, SENSE and GUARD relays are used at each switch point to support low-leakage Kelvin measurements.

  • Page 4: Communication Setup

    WARNING: When installing this equipment in places where access to the main power cord is restricted, such as rack mounting, a separate main input power disconnect device must be provided, in close proximity to the equipment and within easy reach of the operator. WARNING: Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground connections.

  • Page 5: Display And Keyboard

    This installation only needs to be done once. The port automatically becomes available each time the switch is connected and turned on. LAN Setup: Connect the switch to your local network and turn it on. Press SETUP, select 1 (SETUP), 3 (LAN) and press OK.

  • Page 6: Backside Panel

    POWER: Used to turn the unit on or off. Please also note the power switch on the backside panel. INPUT, OUTPUT Used to select relays. CLOSE, OPEN Turns the selected relays on or off. DISCHG Toggles the discharge relays. RESET Opens all relays.

  • Page 7: Maintenance

    WARNING: Do not try to use non-matching connectors or wires. WARNING: The maximum voltage rating for each connector is labeled on the backside panel. Do not apply any higher voltage. This also applies to connections through the matrix. The right side of the backside panel has USB, LAN, RS232 and GPIB communication interfaces, a digital I/O connector, a ground connector stub and the main power jack connector with integrated switch and fuses installed.

WAIT (Input) When pulled HIGH the switch suspends execution.
  • Page 9 Relay numbers Relays are specified by a letter defining the matrix input (A to L) followed by a number defining the matrix output (1 to 12). Alternatively a relay can be specified by a 5 digit number biioo, where b=board (always 1), ii=input and oo=output.
