Explanation  If users do not use the SYSTem:IDN:USER:DEFine <idn_string> command to
reset the ID string of the instrument, the return value is empty when using the
SYSTem:IDN:USER:DEFine? command to query the current user-defined ID
string of the instrument.
 The
*IDN? command queries the current ID string of the instrument.
 Sending the SYSTem:IDN:USER:DEFine <idn_string> command to modify the ID
string of the instrument will overwrite the default ID string of the instrument. A
Factory Reset (send the
*RST command) or Instrument Preset (send the
SYSTem:PRESet command) does not affect the current ID string of the
instrument. You can send the
SYSTem:IDN:DEFault command to set the ID string
of the instrument to the default.
Return
Format
The query returns the current user-defined ID string of the instrument.
Example SYST:IDN:USER:DEF M300_1
SYST:IDN:USER:DEF?
The query returns M300_1.
