Unit returns the current fault and status codes for the Base Unit, Converter A and B, in the form
abcd, where:
a = Base Unit Faults:
0 = No faults
1 = +12V Power Supply 1
2 = +12V Power Supply 2
3 = +5V Power Supply 1
4 = +5V Power Supply 2
5 = +7.8V Power Supply
6 = Flash Checksum
7 = FPGA Done
8 = External Ref Lock Detect
9 = Converter A Not Inserted
A = Converter B Not Inserted
B = Switch Fault
b, c = Converter A and B Faults:
0 = No faults
1 = Synthesizer Lock Detect
2 = Heat-sink Temperature
3 = LNA Current Supply (BDC only)
4 = Low Forward RF Power (BUC only)
d = New Faults:
0 = No change in fault status since last check
1 = Change in fault status, since last check
Command only.

for each section, but
only the highest fault
