Testhead Cards

Testhead Cards

The Testhead Cards task (Figure 3-7) specifies what type of cards to use for the board test.

		You would typically select the minimum number of cards needed, based on the node count. Specifying the minimum requirements may allow the test to be run on other test systems that have fewer resources.

Selecting the cards

1   Enable a module by clicking the Enabled for Testing check box.

2   Select the cards to use for the test by clicking the check boxes for the appropriate slots. To enable a different card in a particular slot, click the name to display a list of cards for selection.

Refer to the notes below on selecting modules and cards.

3   Click Save Board Configuration.

Notes on selecting modules and cards

Modules: A one-module system will have the lower module installed (either Module 1 or Module 3).
Due to the wiring of the testhead, both modules in a bank must be enabled before a module in the other bank can be enabled. For example, if Module 3 is enabled, the next module selected must be Module 2; you will not be able to enable Module 0 or Module 1 before Module 2.
The slots in Modules 0 and 1 are numbered from bottom to top while the slots in Modules 2 and 3 are numbered top to bottom, matching the order in the physical testhead.
ASRU and Control XTP cards: Each module used must have the ASRU card in slot 1 and Control XTP in slot 6 enabled.

ASRU card type:

Choose the asru c revision or asru n revision, depending on the card in use.
To use Cover-Extend, the ASRU card must be enhanced to allow a USB connection to the Cover-Extend signal conditioner card. In this case, select the asru c revision usb or asru n revision usb option.
Note that the ASRU C card and ASRU-N cards cannot be used together in the same machine.
Pin cards: There must be at least one pin card enabled in each module.

If used, only one Utility Card can be installed and enabled in a module.

Declaring External Devices

If a Utility Card is installed and external device(s) will be used, they must be declared. Copy the DLL file for the external device to either of these folders: Agilent_ICT/ext_dev or Agilent_ICT/boards/<board_name>/custom_ext_dev

Then declare the external device as follows:

1   Ensure that the Utility Card is enabled.

2   In the External Devices section, click Add Utility Connection.

3   Enter a name for the external device and select the DLL from the Library File drop-down list.

The software lists the DLLs available in the Agilent_ICT/boards/<board_name>/custom_ext_dev and Agilent_ICT/ext_dev folders. If a particular DLL is present in both folders, the one in the custom_ext_dev folder will be used.

4   Specify where the external device is connected by selecting the device slot ID check boxes (see Table 3-2).

5   Click Add.

Table 3-2    Device slot IDs

	Utility Card
	Slot 1	Slot 2	Slot 3
Module 3	xd1	xd2	xd3
Module 2	xd4	xd5	xd6
Module 1	xd7	xd8	xd9
Module 0	xd10	xd11	xd12
