2. A green mark means the corresponding test is a success. You may
either quit or continue with the next test if necessary.
3. An illustration of data tables which reveal information on how the
tested part is working.
Available tests are listed below.
8.2.1 Speaker Test
It checks the normal functionality of the loud speakers on the system.
8.2.2 System memory
Test all accessible registers and memories in the scanning unit.
8.2.3 TFC test
Test the connection between the DBF board and the DBTR board. A red
mark implies there is connection error.
8.2.4 EC↔FIFO
Test the FIFO functionality of the DBF board. A red mark implies connec-
tion error.
8.2.5 Receive bus
Test the connection of receive bus on the DBF board. A red mark implies
connection error.
8.2.6 Detector to FIFO
Test the functionality between demodulation circuit and FIFO circuit on the
DBF board.
8.2.7 ADC Test (Rx on)
While Rx is on (the receive channel is on), it tests AD converter, and also
signal channels on the DBF board by examining amplitude and phase. The
normal functionality of AD conversion requires that both system memory
and receive bus are functional, so either Receive bus test or System memory
test fails implies that ADC Test (Rx on) fails.
