Message terminator
A terminator informs the instrument that it has reached the end of a SCPI message. The following
message terminators are permitted.
Terminator Description
Decimal 10 or hexadecimal
New line and end or identify
In the examples in this manual, there is an assumed message terminator at the end of each
message.
Multiple commands in a message
You can group multiple SCPI command messages and send them as a single message with one
message terminator. There are two important considerations when sending several commands in a
single message.
• Separate each command with a semicolon (;)
• Header paths influence how the instrument interprets commands
The header path is a string that is inserted in front of every command in a message. The header path
in the first command message is a null string. For each subsequent command with the same header
path, the header is implied. For example:
CURR:LEV 3; PROT:STAT OFF
In the example above, the header path is CURR. Because the two commands are separated with a
semicolon (;) and the commands are in the same header path, the header path CURR is not needed
for the second command. The instrument automatically interprets the command following the
semicolon as:
CURR:PROT:STAT OFF
If CURR is explicitly included in the second command in the first example above, it is semantically
wrong. The instrument will interpret the second command as CURR:CURR:PROT:STAT OFF, and an
error will occur.
