Read Fault Log
Use this command to query a single entry within the fault log. The fault log stores up to 200 of the most recent
faults. Each fault is tagged with a decimal number between 1 (most recent) and 200 (oldest). If the fault log
exceeds 200 faults, the oldest fault in the list will be cleared.
The number of total faults in the log can be queried using the Read Fault Count command.
Query:
FSTA:LOG? <number>
<number>:
A decimal number between 1 and 200 representing the memory location within
the fault log.
Response Format:
<hex error>,<power time>,<rf time><LF>
<hex error>:
A hexadecimal number (0000 to FFFF) representing the fault code, padded
with zeros to always be 4 characters wide.
<power time>:
The total power on hours (0 to 100000).
<rf time>:
The total hours with RF enabled (0 to 100000).

following command:
FSTA:LOG? 1<LF>
Response 1:

(Fault 0003 occurred at 428 power on hours and 37 RF on hours)
