Locate SCPI Command Errors

:SYSTem:ERRor:VERBose OFFON01

:SYSTem:ERRor:VERBose?

Adds additional information to the error messages returned by the SYSTem:ERRor? command. It indicates which SCPI command was executing when the error occured and what about that command was unacceptable.

<error number>,”<error message>;<annotated SCPI command>”

Example:	First set SYST:ERR:VERBOSE ON
	If the command SENSe:FREQuently:CENTer 942.6MHz
	is sent, then sending SYST:ERR? returns:

−113,”Undefined header;SENSe:FREQuently:<Err>CENTer 942.6MHz $<NL>”

The <Err> shown after FREQuently shows you the spelling error. (The $<NL> is the typical representation for the command terminator.

If the command SENSe:FREQuency:CENTer 942.6Sec is sent, then sending SYST:ERR? returns:

−113,”Invalid suffix;SENSe:FREQuency:CENTer 942.6Sec<Err> $<NL>”

The <Err> shown after Sec shows you the invalid suffix.
