SYSTem Commands
l
The front-panel ERR annunciator turns on when one or more errors are currently stored in the error queue. Error
retrieval is first-in-first-out (FIFO), and errors are cleared as you read them. When you have read all errors from
the error queue, the ERR annunciator turns off.
l
If more than 20 errors have occurred, the last error stored in the queue (the most recent error) is replaced with -
350,"Error 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 instrument responds with +0,"No error".
l
The error queue is cleared by the *CLS and when power is cycled. It is not cleared by a *RST.
l
Errors have the following format (the error string may contain up to 255 characters).
<
error code >,< error string >
For a list of error codes and message strings, see SCPI Error Messages .
SYSTem:SECurity:IMMediate
Clears all user memory and reboots the instrument. This command is typically used to prepare the instrument for
removal from a secure area. It writes all zeros to flash memory and then performs a full chip erase as per the man-
ufacturer’s data sheet. Identification data such as instrument firmware, model number, serial number, MAC address,
and calibration data is not erased. After the data is cleared, the instrument is rebooted.
This procedure is not recommended for use in routine applications because of the possibility of unintended loss of data.
Parameter Typical Return
(none) (none)
Sanitizes the instrument: SYST:SEC:IMM
SYSTem:VERSion?
Returns the SCPI version that the instrument complies with. Cannot be determined from front panel.
Parameter Typical Return
(none) <"version">
Return the SCPI version: SYST:VERS?
l
The command returns a string in the form "YYYY.V", where YYYY represents the year of the version and V rep-
resents a version for that year.
*IDN?
Identification Query . Returns instrument’s identification string, which contains four comma-separated fields. The first
field is the manufacturer's name, the second field is the instrument model number, the third field is the serial number,
and the fourth field is the firmware revision.
Parameter Typical Return
(none) Agilent Technologies,N8925A,MY00123456,A.01.01
Return the instrument's identification string: *IDN?
