SCPI Data Types
The SCPI language defines different data formats for use in program
messages and response messages. Instruments are flexible listeners and
can accept commands and parameters in various formats. However, SCPI
instruments are precise talkers. This means that SCPI instruments always
respond to a particular query in a predefined, rigid format.
<boolean> Definition
Throughout this document <boolean> is used to represent ON|OFF|<NRf>.
boolean parameters have a value of 0 or 1 and are unitless. ON
corresponds to 1 and OFF corresponds to 0.
On input, an <NRf> is rounded to an integer. A nonzero result is
interpreted as 1.
Queries always return a 1 or 0, never ON or OFF.
<character_data> Definition
Throughout this document <character_data> is used to represent
character data, that is, A - Z, a - z, 0 - 9 and _ (underscore). For example:
START and R6_5F. The format is defined as:
