separate adjacent Parameter.
Space
You must use blank characters, [TAB] or [Space] to separate Parameter with
key words of commands.
Generic commands (*)
The IEEE-488.2 standard defines a set of common commands that perform
functions such as reset, self-test, and status operations. Generic commands
always start with a asterisk (*) and occupy 3 character sizes, including one or
more Parameter. Key words of a command and the first parameter are
separated by a space. Semicolon (;) can separate several commands as
follows:
*RST; *CLS; *ESE 32; *OPC?
Command terminator
Command strings sent to the instrument must end with a <Newline> (<NL>)
character. IEEE-488 EOI (End or Identify) information can be used as <NL>
character to replace termination command string of <NL> character. It is
acceptable to place one <NL> after a <Enter>. Termination of command string
always resets current SCPI command path to root level.
NOTE
As for every SCPI message with one query sent to the instrument, the
instrument will use a <NL> or newline sign (EOI) to terminate response of
return. For example, if "DISP:TEXT?" is sent, <NL> will be placed after
the returned data string to terminate response. If an SCPI message
includes several queries separated by semicolon (such as
"DISP?;DISP:TEXT?"), <NL> will terminate response returned after
response to the last query. In all cases, the program must read <NL> in
response before another command is sent to the instrument, otherwise
errors will be caused.
1.6 Data Type
SCPI language defines several data types used for program message and
response messages.
⚫ Numerical parameter
Commands requiring numerical parameter support the notations of all common
decimal notations, including optional signs, decimal points, scientific notation,
