Parameter Types
Several different data types are defined for use in program messages and
response 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 {ON|OFF|1|0}
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 {BUS|EXT|IMM|NONE}
Numeric Parameters
Numeric parameters are number representations such as decimal points,
optional signs, and scientific notation. Values such as MINimum and
MAXimum are accepted as substitutes for numbers. When DEFault is
provided as a parameter, the machine selects the default value
automatically. No units' suffix should be included with the parameter,
only support for defaults units is available. 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>|MAX|MIN}
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. Quote
delimiters may be included in the string by typing the quotation marks
twice without any characters in between. The following is an example of
a command that uses string parameters:
