Medalist ICT System Hardware

Medalist ICT System Hardware

Figure 1 shows a typical Medalist ICT test station. The appearance of your test system will vary depending on the system model and combination of optional features.

The common components that make up the Medalist ICT system include:

Testhead

The testhead contains the hardware resources required to execute tests. There are three types of testheads:

1-module testhead
2-module testhead
4-module testhead

The descriptions refer to the maximum number of modules the testhead can have, not to the number of populated modules in the system. For example, a 4-module system might have only one or two populated modules, but it could be upgraded to have three or four.

Each module in the testhead holds the following cards:

A Mother Card
A Module Control Card
An ASRU Card
Up to 9 pin cards
Testhead Controller

The testhead controller is the computer that controls the test system. The specifications and options available depend on the system purchased.

Test Fixture

The test fixture is the hardware interface between the testhead and the board or device under test (DUT).

Support Bay

A support bay is required on four-module systems and contains the DUT power supplies and any optional external instrumentation. In two-module and one-module systems, the DUT power supplies are located within the testhead.

Table 1 and Table 2 describe the test station and operator controls.

Table 1    Test station controls

Item	Description
Emergency Shutdown Switch	The Emergency Shutdown switch is the large red button located at the lower left corner on the front of the testhead (Figure 1). Press this switch to power down the testhead and its associated equipment in an emergency situation. It turns off all AC power to the testhead, and is equivalent to turning off the main circuit breaker on the rear of the pod.
Main Power Switch	Controls the incoming line voltage and is located at the rear of the pod.
Testhead Rotation Switch	Rotates the testhead into any position from 0 to 90 degrees from the horizontal. It is located in the pod (open the pod door to access it).

Table 2    Operator controls

Item	Description
Operator Interface	Graphical user interface lets the operator load and run testplans.
Operator footswitch	Functions like the START button in the operator screen; can be used when the operator’s hands are busy.
Bar code scanner	Used to save time and minimize errors when entering board serial numbers.
Guided probe	Used by the operator for manual probing of circuits.
