SYSTem:ERRor:COUNt?
Returns the number of errors in the error queue.
Parameter Typical Return
(none) +11
Return the number of errors in the error queue: SYST:ERR:COUN?
The returned value always begins with a + character, even if the number is 0.
The Err annunciator turns on when any error is in the error queue. Error retrieval is first-in-first-out,
and errors are cleared as you read them. When you have read all errors from the error queue, the Err
annunciator turns off.
If more than 16 errors have occurred, the most recent error is replaced with -350,"Error queue
overflow". No additional errors are stored until you remove errors from the queue. Reading the error
queue when it is empty yields the m0,"No error".
The error queue is cleared by *CLS and power cycling. It is not cleared by *RST.
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 error strings, see SCPI Error Messages .
SYSTem:SECurity:IMMediate
Clears all user memory (including stored states) and reboots the instrument in the *RST state. This
command is typically used to prepare the instrument for removal from a secure area. Instrument
identification data (instrument firmware, model number, serial number, MAC address) and calibration
data is not erased.
The sanitization procedure is not recommended for use in routine applications because of the
possibility of unintended loss of data.
Parameter Typical Return
(none) (none)
Sanitize the instrument: SYST:SEC:IMM
