9 Controlling your SLED with SCPI commands
Remote communication with the CohesionSCPI service is achieved through the Standard Commands for Programmable Instruments (SCPI). Support
for VISA I/O API over TCP/IP is provided by the VXI-11 compliant CohesionSCPI service. With VISA communication drivers installed on the client, the
implementation of VISA programming within environments such as MATLAB becomes available.
This section provides information on programming conventions and on commands that are available for communication with the CohesionSCPI
service remotely using the VISA I/O.
For details on programming applications, refer to section

).
<value>
Is numerical data, an integer, a decimal, exponential (10e-9 or 5.8e6) or string.
[VALUE1 | VALUE2]
A parameter choice. The ‘|’ separates the unique parameters available, only one of the choices can be used. In
the example, either the input parameter
[VALUE1]
or
[VALUE2]
can be used, but not both. Some commands
may have more than two choices available. This parameter can be omitted where the command has a default
defined in the command description.
