Command Syntax

Command Statement Rules Overview
Besides the standard notation of SCPI described above,
please remember the following rules in programming:
• command statements read from left to right
• use either long form or short form of keywords, but do
not use both
• no separating space between the keywords, only use a
colon to separate keywords of different levels
• always separating a keyword from a variable with a space
• always separating a variable from its unit with a space (if
variable has a unit).
Command Example
A typical command is made up of key words set off by
colons. The key words are followed by parameters that can
be followed by optional units.
Example 1 :TRIGger:SEQuence:VIDeo:LEVel 2.5V
The instrument does not distinguish between upper and
lower case letters. In the documentation, upper case letters
indicate the short form of the key word. The upper and
lower case letters, together, indicate the long form of the key
word. Either form may be used in the command.
Example 2 :Trig:Seq:Vid:Lev 2.5V is the same as
:trigger:sequence:video:level 2.5V.
NOTE
The command :TRIGG:Sequence:Video:Level 2.5V is not
valid because
:TRIGG is neither the long, nor the short form of the
command.
