Fig. 6-4: Relationship between the commands CONFigure, READ?, FETCh? and MEASure?
Strictly speaking, the CONFigure command is not a measurement command because
it does not yield data and only configures a measurement. It differs from the other three
high-level measurement commands as follows: a question mark at the end of the com-
mand provides information on current settings. With other commands, the question
mark is compulsory and shows that the measured data is queried.
In general, the low level commands which are determining qualitative parameters such
as measurement mode and calculation function are replaced by keywords in the com-
mand header.
Example:
Selection of measurement mode "T'slot"
is performed by low level command
SENSe:FUNCtion 'POWer:TSLot:AVG' or by all high level commands which con-
tain TSLot in the header, e.g. MEASure:TSLot:.... With high level command, in
addition to selecting the measurement mode several presettings for this mode are per-
formed.
Selection of the calculation function "Sum" is performed with low level command
CALCulate:MATH 'SENS1+SENS2' or by all high level commands which contain
SUM in the header, e.g. MEASure:TSLot:SUM.
Quantative parameters such as number of slots are set by means of a parameter list
which is sent with the MEASure and CONFigure commands. The parameter list is
specific for each measurement mode. Thus, a configuration that requires several low
level commands is achieved by one high level command.
Example:
MEASure:XTIMe:RAT? 312,5,(@1),(@2)
replaces the low level commands
TRIGger:SOURce EXT
TRIGger:COUNt 1
TRIGger:DELay:AUTO ON
SENSe:AVERage ON
SENSe:FUNCtion 'XTIMe:POWer'
SENSe:TRACe:TIME 5
SENSe:TRACe:POINts 312
CALculate:MATH '(SENS1+SENS2)'
INITiate:CONTinuous OFF
