OutP, OUTPUt, ouTPut, or OUTp are all valid).
FIGURE 6-1. MESSAGE STRUCTURE
6.5.2 KEYWORD SEPARATOR
If a command has two or more keywords, adjacent keywords must be separated by a colon (:)
which acts as the keyword separator (e.g., CURR:LEV:TRIG). The colon can also act as a root
specifier (paragraph 6.5.7).
6.5.3 QUERY INDICATOR
The question mark (?) following a keyword is a query indicator. This changes the command into
a query. If there is more than one keyword in the command, the query indicator follows the last
keyword. (e.g., VOLT? and MEAS:CURR?).
