The Multicoil Receive Chain Tool provides a means of diagnosing problems in Multicoil
Receive (MCR) chain hardware, without use of coils. The tool sends signals down the
individual paths to isolate specific channels in the receive chain. The tool
’ s Graphical User
Interface (GUI) guides the user through the various steps involved in running the tool and
troubleshooting the problem. The GUI has built-in instructions and detailed setup instructions,
troubleshooting flowcharts and documents that will help facilitate rapid diagnosis of the
problem. There are two levels of tests that can be run using the MCR III tool: Default and
Individual. Once you've decided to use MCR III tool, determine which level of test your
situation requires. The default and port-specific levels of tests offer increased user-friendly
automation that is been omitted from the individual tests by design. Therefore, it is
imperative to identify which level of tests you need to perform and then follow the
instructions for that specific level.
1) Port A Default Tests
This test must be passed during the MR installation.
In most scenarios, this is the first test that should be run when using the MCR tool.
If this test fails, individual tests can be run to further isolate the failing component.
2) Port A Individual Tests
These tests are designed to run after the default test indicates a failure.
3) Express Coil Test For Fixed Table
This test must be passed during the MR installation.
