A comma is used to separate multiple arguments of a command.

You can query the current value of most parameters by adding a question mark (?) to the command. For
example, the following command sets the trigger count to 10:TRIG:COUNT 10.Then, you can query the
count value by sending the following command:
TRIG:COUNT?
5 Space
Must use a blank character, [TAB] or [space] to separate the parameters from the command keyword.
6 General Command
（
*
）
XXXX The IEEE-488.2 standard defines a common set of commands that perform functions such as reset,
self-test, and status operations. For example: *RST.
7 Command Terminator
（
<NL>
）
The command string sent to the instrument must end with a <newline> (<NL>) character.The IEEE-488 EOI
(end or identification) information can be treated as an <NL> character, and used to terminate the
command string instead of the <NL> character. A <backspace> followed by a <NL> is also
possible.Command string termination always resets the current SCPI command path to the root level.
6.3.2.3 Command Abbreviation Rules
1) Use below rules to determine the abbreviations for any SCPI commands.
2) If the length of the command keyword is less than or equal to four characters, there is no abbreviated
form. For example: :AUTO=:AUTO
3) If the fourth character of the command keyword is one of v, o, w, e, l, then remove it and all characters
following it. For example: :immediate=:imm
4) Special rule: The abbreviated form of the following command uses only the first two characters of the
keyword: :TCouple=:tc
5) If the fourth character of the command keyword is a consonant, leave it and remove all subsequent
characters. For example::format=:form
6) If the command contains a query token (?) or an unselectable number in the command keyword, it
must be included in the abbreviated form. For example: :delay?=:del?
7) The command keywords or characters contained in square brackets ([]) are optional and may not be
included in the program code.
