Adds additional information to the error messages returned by the
:SYSTem:ERRor?
command. It indicates which SCPI command was executing
when the error occurred and what about that command was unacceptable.
<error number>,”<error message>;<annotated SCPI command>”
The maximum length of the <annotated SCPI command> is 80 characters. If the
error occurs in a SCPI command longer than 80 characters, the <Err> sentinel is
placed at the end of the <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:FREQ:CENTer 942.6Sec
is sent,
then sending SYST:ERR? returns:
−
131,”Invalid suffix;SENSe:FREQuency:CENTer 942.6Sec<Err> $<NL>”
The <Err> shown after Sec shows you the invalid suffix.
Factory Preset

interfaces.
