Note : SCPI stems from IEEE488.1 and IEEE 488.2. Although the IEEE 488.2 standard
addressed some instrument measurements, it principally dealt with common commands and syntax
or data formats. Please refer to the IEEE488.2 and SCPI reference manual for more information.

Response messages are data from the meter to a computer in response to a query. A
query is a command followed by a question mark. Table 7-2 contains explanations
of data types.
