152 Keysight E1406A User Manual and SCPI Programing GuideKeysight E1406A Command Reference DIAGnostic Subsystem:COMMunicate :SERial[0][:OWNer]?DIAGnostic:COMMunicate:SERial[0][:OWNer]? returns the current "owner" of thebuilt-in serial interface. The values returned will be; SYST, IBAS, or NONE.Comments– Related Commands: DIAG:COMM:SER[0][:OWN]ExampleDetermine Which Instrument has the Serial InterfaceDIAG:COMM:SER? Note that 0 (zero) and :OWNer are implied.enter statement Statement returns the string SYST, IBAS, or NONE.:COMMunicate :SERial[n]:STOReDIAGnostic:COMMunicate:SERial[n]:STORe stores the serial communicationsparameters (for example, BAUD, BITS, PARity, and so on) into Non-volatilestorage for the serial interface specified by [n] in SERial[n].Comments– Until DIAG:COMM:SER[n]:STORe is executed, communication parametervalues are stored in volatile memory, and a power failure will cause thesettings to be lost.– DIAG:COMM:SER[n]:STORe stores the serial interface’s communicationsparameters. Card number 0 (in place of [n]) specifies the commandmodule’s built-in interface while 1 through 7 specifies one of up to sevenKeysight E1324A B-size plug-in serial interface modules. Be aware that theKeysight E1324A module stores its settings in an on-board EEROM. ThisEEROM write cycle takes nearly one second to complete. Wait for thisoperation to complete before attempting to use that serial interface.– The Keysight E1324A’s EEROM used to store its serial communicationsettings has a finite lifetime of approximately 10,000 write cycles. Even ifyour application program sent the DIAG:COMM:SER[n]:STORe commandonce every day, the lifetime of the EEROM would still be over 27 years. Becareful that your application program sends theDIAG:COMM:SER[n]:STORe command to an Keysight E1324A no moreoften than is necessary.– Related Commands: All SYST:COMM:SER[n]? commands.ExampleStore the Serial Communications Settings in the Third Keysight E1324ADIAG:COMM:SER3:STOR
