SCPI Command Reference 4-3A semicolon ( ; ) is used to separate commands within the samesubsystem, and can also minimize typing. For example, sendingthe following command string:TRIG:SOUR:ADV INT;BURS ON;INT:RATE 5e-3is the same as sending the following three commands:TRIG:SOUR:ADV INTTRIG:BURS ONTRIG:INT:RATE 5e-3Use the colon and semicolon to link commands from differentsubsystems. For example, in the following command string, anerror is generated if both the colon and the semicolon are not used.OUTP:STATE ON;:TRIG:STAT ONThe MIN and MAXParametersSubstitute MINimum or MAXimum in place of a parameter for somecommands. For example, consider the following command:FREQuency {|MINimum|MAXimum}Instead of selecting a specific frequency, substitute MIN to set thefrequency to its minimum value or MAX to set the frequency to itsmaximum value.QueryingParameter SettingQuery the current value of most parameters by adding a questionmark ( ? ) to the command. For example, the following commandsets the output function to square:SOUR:FUNC:SHAP SQRQuery the output function by executing:SOUR:FUNC:SHAP?Query ResponseFormatThe response to a query depends on the command sent to theinstrument to generate the query response. In general, a responseto a query contains current values or settings of the synthesizer.Commands that set values can be queried about their currentvalue of the setting. Commands that set modes of operation canbe queried about their current mode setting. IEEE-STD-488.2common queries generate responses which are common to allinstruments that are connected to the GPIB interface.SCPI CommandTerminatorA command string sent to the function generator must terminatewith a character. The IEEE-STD-488 EOI (end-or-identify) message is interpreted as a character. A followed by a is also accepted.Command string termination always resets the current SCPIcommand path to the root level.Artisan Technology Group - Quality Instrumentation ...
