8 Communication Command
Reference
8.1 Model 1936/2936 Series Remote Interface Commands
A complete listing of the commands supported by 1936/2936-R series power
meters is provided below.
8.2 Command Overview
There are two types of commands: commands that cause the power meter to
take a desired action, and queries that return a stored value or state of the
power meter. Queries must end with a question mark (?), while commands
may require parameter(s) to follow:
PM:Lambda 810
For example, the value “810” in the command PM:Lambda 810 sets the
wavelength for the currently selected channel to 810. The table below
summarizes all the commands and queries supported by the 1936/2936-R
series power meters. The command/query MUST contain all of the letters,
which are shown in upper case in this table. The lower case letters shown
with the commands are optional, and may be used for clarity. If any of the
optional letters are used, then all of the optional letters are now required for
the current command.
The commands may be sent to the instrument in either upper or lower case or
in any combination. For example, the following commands are equal:
PM:Lambda 810
PM:L 810
pm:L 810
Pm:L 810
COMMAND EXECUTION:
The controller interprets the commands in the order they are received and
execute them sequentially. If a set of commands have to be executed closer
to each other, these commands can be sent to the controller simultaneously
by creating a command string with semicolon (;) used as a command
separator. The command string length should not exceed 50 characters. In
the example shown below, a command string was created with semicolon
