Commands not recognized have no effect
on the unit’s operation and will set the cor-
responding bits in the Standard Event Status
Register. SCPI commands that end with a ques-
tion mark ‘?’ are queries. All queries should
be followed by reading their response to avoid
data loss.
Semicolon ‘;’ is used to separate more
commands written on one line.
Terminators: For GPIB interface each
command line must end with line feed <lf>.
Response from the device also returns line feed
<lf>.
