:SYSTem:ERRor:VERBose?
Adds additional information to the error messages returned by the
SYSTem:ERRor? command. It indicates which SCPI command was
executing and where in that command the error was detected.
<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.
Factory Preset
and *RST: Off. This parameter is persistent, which means that it
retains the setting previously selected, even through a
power cycle.
Remarks: The verbose SCPI error debugging state is global to all
the SCPI interfaces.
