SCPI Command Reference
Understanding SCPI Commands
Parameter Several different data types are defined for use in program messages and response Types messages.
Boolean Parameters
Boolean parameters are single binary conditions such as 1 and 0, or ON and OFF. The following is an example of a command that uses Boolean parameters:
SYST:COMM:GPIB:PONS {ONOFF10}
Discrete Parameters
Discrete parameters are used when program settings have a limited number of values. If you query a discrete parameter, the response will always be in the short form with all uppercase letters. The following is an example of a command that uses discrete parameters:
TRIG:SOUR {BUSEXTIMMNONE}
Numeric Parameters
Numeric parameters may include decimal points, +/- signs, and scientific notation. Values such as MINimum and MAXimum are sometimes accepted as substitutes for numbers. When DEFault is provided as a parameter, the machine selects the default value automatically. You can may also use unit suffixes such as, V, A, or W where appropriate. In cases where specific numeric values are accepted, the power unit will round the input parameters. The following is an example of a command that uses numeric parameters:
VOLT:PROT {<voltage>MAXMIN}
String Parameters
String parameters are used when a series of ASCII characters is required. Strings must be enclosed within single or double quotations. The beginning and ending quotation marks must be matching. The following is an example of a command that uses string parameters:
CAL:STAT ON,“0000”
