Condition Errors 501 to 599, Frequency

This series of errors corresponds to the bits in the
STATus:QUEStionable:FREQuencyr register. The second column in the table
shows the corresponding bit.
An event with the error number shown in the table means the condition has
been detected. When the condition is cleared, an event with the error number
plus 1000 is generated. These error numbers can be seen in the Show Errors
screen, along with the DETECTED and CLEARED indicators.
For example, error 503 indicates a Frequency Reference Unlocked condition
has been detected, error 1503 indicates that failure has been cleared.
