Commands usually begin with a colon (:), in special case, such as IEEE
commands will begin with (*), it represents operations the oscilloscope will take.
Queries are formed by adding a question mark (?) at the end of the commands.
The return values of the queries are mostly expressed in scientific notation.
Forms of commands and inquiries have different programme datum usually. But
some others are not need to input the programme datum.

be selected. For example, {ON | OFF} indicates that only ON or OFF may be
available, not both.

5. Triangle Brackets < >
