Programmable AC Source 6460/6463/6490 User’s Manual
Query Syntax: *SRE?
*TST?, Self-Test Query
This query causes an internal self-test and reports result.
Return parameters <NR2>
5.6.2 Instrument Command Dictionary
The commands are listed in alphabetical order. Commands followed by question marks (?)
take only the query forms. When commands take both the command and query forms, they
are noted in the syntax descriptions.
FETCh | MEASure
[ : SCALar]
: CURRent
: AC? Query AC rms current
: CREStfactor? Query current crest factor
This command lets the user get measurement data from the AC source. Two measurement
commands are available: MEASure and FETCh. MEASure triggers the acquisition of new
data before returning data. FETCh returns the previously acquired data from measurement
buffer. Individual outputs of a multi-phase source are specified by the setting of INSTrument :
NSELect command.
FETCh [ : SCALar] : CURRent : AC?
MEASure [ : SCALar] : CURRent : AC?
Return parameters <NR2>
These queries return the rms current which is being output at the output terminal.
FETCh [ : SCALar] : CURRent : CREStfactor?
MEASure [ : SCALar] : CURRent : CREStfactor?
Return parameters <NR2>
These queries return the output current crest factor. It is the ratio of peak output current to
rms output current.
FETCh | MEASure
[ : SCALar]
: FREQuency? Query the output frequency
FETCh [ : SCALar] : FREQuency?
MEASure [ : SCALar] : FREQuency?
Return parameters <NR2>
These queries return the output frequency in Hertz.
FETCh | MEASure
[ : SCALar]
