SYSTem:ERRor?
This command queries the power supply’s error queue. When
the front- panel ERROR annunciator turns on, one or more
command syntax or hardware errors have been detected. Up
to 20 errors can be stored in the error queue. See
Chapter 4, “Error Messages” for more details.
• Errors are retrieved in the first- in- first- out (FIFO) order.
The first error returned is the first error that was stored.
When you have read all errors from the queue, the ERROR
annunciator turns off. The power supply beeps once each
time an error is generated.
• If more than 20 errors have occurred, the last error
stored in the queue (the most recent error) is replaced
with - 350, “Queue overflow”. No additional errors are
stored until you remove errors from the queue. If no
errors have occurred when you read the error queue, the
power supply responds with +0, “No error”.
• The error queue is cleared when power has been off or
after a *CLS (clear status) command has been executed.
The *RST (reset) command does not clear the error
queue.
SYSTem:VERSion?
This query returns the power supply to determine the
present SCPI version. The returned value is a string in the
form of YYYY.V where the Y represents the year of the
version, and the V represents a version number for that year
(for example, 1995.0).
