SCPI Recorder
While developing your programs, it is recommended that you use the SCPI Recorder. As you click FlexOTO's GUI, the SCPI Recorder records the equivalent SCPI commands. An opened SCPI Recorder dialog only applies to the currently selected FlexOTO Hardware Diagram or Station tab. FlexOTO closes the SCPI Recorder dialog as soon as you click on another tab. You must reopen the SCPI Recorder for the new tab.
When you've recorded your commands, you can play them back and save them as a macro. Click REC and the recorder performs the following tasks:
- Captures most setting changes (mouse clicks or keyboard presses).
- Translates the setting into an equivalent SCPI remote-programming command.
- Records the SCPI command within the dialog.
Click REC to begin recording. The button turns red to alert you that any mouse clicks or keyboard presses will be recorded. When you have captured all your commands, click the record button again to end the recording.
During recording, click STOP to end the recording.
Click Play to play back your recording and observe the commands as they are executed. Playback always starts at the highlighted command, which is shown in a blue box as seen in the above figure. Click any command in the dialog to highlight that command. Use Playback Speed to control the rate that the commands are played: Slow, Normal, or Fast.
During playback, click PAUSE to temporarily stop the playback.
During playback, click Device Clear when a command is waiting a unacceptable length of time to complete. This can happen, for example, during limit testing when a command locks the remote interface until 100 failed samples are detected. This task could take a very long time.
:LTESt:MTESt:FAILures 100; *OPC?
Click Clear to delete your recorded commands from the dialog.
Click Save to save your recorded commands into a script file (.scpi) that can be reloaded into the dialog at any time by clicking Load.
The default user data folder for saving script files is \SCPI Scripts.
SCPI script file are ASCII files, so you can edit them as well as create new script files using a text editor. SCPI scripts are often small snippets of code that may depend on FlexOTO being set to very specific settings. As a result, your scripts may not work in the same manner in different situations. This can be alleviated by starting your scripts with commands that configure starting conditions. For example, the first few lines in the following code configures FlexOTO from a default setup before making a rise time measurement. To include comments in your scripts, precede the comments with two forward-slash characters as shown in this example script:
:TPRogram:SETup:ADD :TPRogram:SETup:MEASurements OOMA,OER,APOWer,PPHRatio,WDATa,EDIMage :TPRogram:SETup:OOMA:UNITs DBM
When FlexOTO is installed, a registry entry is created to associate script files (.scpi) with Notepad. This makes it easier to open script files.
