Description of Arguments
(Note that all arguments are ASCII numeric codes
to Query
Query Only.
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 = 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
Query only.
Returns the firmware type loaded into the unit.
i = Bulk Image Number (1 or 2)
a = Firmware Image
b = Firmware Revision
c = Firmware Date
Command only.
Resets internal pointer to allow RNE? Queries to start at the
beginning of the stored events log.
Example: IEP=

Note: Each section has
faults listed in order of
priority. For each section,
only the highest priority
fault is returned. There may
be multiple faults for each
section, but only the
highest fault is returned.
