2 Purpose

This test confirms that the GP can detect skewed data or a missing clock signal on the fiber optic cable connecting the STIF to the GP.

3 Components Tested

  • GP

  • Fiber optic cable between GP and STIF

4 Requirements

None

6 Test Sequence

  1. SCP programs the WARP to send out test data.

  2. WARP sends the test data to STIF.

  3. STIF forwards the data to GP over the fiber link.

  4. GP verifies the data and sends the test results to SCP over the MDS link.

7 Expected Results

Output values are judged pass or fail. In the event of failure, the details of the failure can be found in the GE System Log.

note:

Other than Test Iterations, the Test Options settings should not be changed from their default settings unless instructed to do so by a GE Healthcare engineer. There are very few circumstances when these settings ever need to be changed.
