Error Messages
If an error condition occurs in the synthesizer , it will always be reported to
both the front panel and HP-IB error queues . These two queues are viewed
and managed separately . The 4
MSG
5 key is used to view the contents of the
front panel error queue . The HP-IB query \SY ST em:ERRor?" is used to view
the contents of the HP-IB error queue .
If there are any error messages in the front panel error queue , the front panel
MSG annunciator will be lit. Pressing the 4 MSG 5 key repeatedly until the MSG
annunciator turns o will empty the front panel error queue . The 4 MSG 5 key
has no aect on the HP-IB error queue . Emptying the HP-IB error queue
has no aect on the front panel queue , therefore , it will not aect the MSG
annunciator .
There are some special error types that are called permanent errors .
P ermanent errors remain in the error queues until the error condition is
cleared. Pressing the 4 MSG 5 key will empty the front panel error queue , but
the permanent errors will be re-reported if the error conditions still exist.
In the HP-IB error queue , the permanent errors are re-reported after the
message , 0,\No error" is read using the \SY ST em:ERRor?" query or after the
\*CLS" command is executed.
