Condition Categories

Errors Condition Errors notify you that the instrument cannot make valid measurements while the
condition is present.
Examples of error conditions are "LO Unlocked" or "Alignment required".
A Condition Error exists for a period of time, so it has associated "Detected" and "Cleared" events.
(For example, "LO Unlocked" or "External reference out of range".)
Condition Errors are displayed in the front panel. The Detected and Cleared Events associated with
each Condition Error message are logged in the error queues.
Warnings Condition Warnings appear when a requested operation has completed successfully, but there are
modifications and/or side effects.
For example, if you set the sweep time too fast for a measurement to meet the instrument
specifications then the "Meas Uncal" message is displayed until you slow down the sweep time.
A Warning Condition exists for a period of time, so it has a "Detected" event and a "Cleared" event.
Condition Warnings are displayed in the front panel, but are not sent to SCPI. They may set status
bits in the SCPI Status tree (see
Instrument Messages
"Status Register System & SCPI STATus Subsystem" on page 114).
