Troubleshooting Self Test 704

Self test 704 validates the 100 MHz Reference clock signal that originates on
the A3 RF assembly and is the clock pulse for the ARB FPGA on the A2 Vector
assembly. If the 100 MHz clock is inadequate in amplitude or frequency the
cause likely originates from the A3 RF assembly.
If self test 704 fails, see the "100 MHz Reference Signal" section in Chapter 12,
"Baseband Generators" to verify the level of the 100 MHz reference signal.
