Figure 12: Delay / pattern generator workspace

6.1.4

SCPI Console

The SCPI Console workspace can be used to manually issue SCPI commands to the Time Controller
device, load previously saved device configurations, and view the SCPI commands that the Time
Controller GUI has been pushing to the device.

Figure 13: SCPI Console workspace

To issue SCPI commands to the Time Controller device, type the command in the input field at the
bottom of the workspace and click

Send

.

To load a previously saved device configuration, click the folder icon on the right-hand side, and
select the desired configuration file. Device configuration files are generated by

navigating to ‘File >

Save Settings’

, saving the current device settings as a

‘

.bin

’

file with the name and location of your

choice.

Commands issued through the SCPI Console, or any other means outside of the
Time Controller GUI, will not be reflected in the Time Controller GUI. The
Time Controller software only registers a change in device parameter when the
command is issued via the Time Controller GUI.
