7-3-5 RFT Diagnostic Tests (for RFT Configuration)
The RFT diagnostic tests include the tests listed below:
• Board Test: General RFT board test which activates the remaining tests sequentially. Each of
these tests can also be performed independently.
• Self Test 1: Short generic board test, generated in a local DSP.
• Self Test 2: High level board test, generated in a local DSP. Self Test 2 lasts six minutes.
Note: Before performing the RFT test, perform the IMP and VME Bus tests, as described in the Image
Port (IMP) Diagnostic Tests (for RFT Configuration) section, on page 7-13 and in the VME Bus
(VME) Diagnostic Tests (for RFT Configuration) section, on page 7-15. If the RFT test is
performed without first performing these tests, and errors are identified, you must perform the
VME Bus test, and then the IMP test, to ensure that the RFT board is the source of the error.
