:LTESt:LLINe:SWAVeform:FUNCtion:STATe
Command Syntax
:LTESt:LLINe:SWAVeform:FUNCtion{1:64}:STATe {DISK | MEMory | OFF}
Where {1:64} identifies a function.
Query Syntax
:LTESt:LLINe:SWAVeform:FUNCtion{1:64}:STATe?
Description
Specifies the reporting action for the selected function waveform upon completion of limit testing for a limit line test. Use the command argument to select or turn off the reporting action. To disable the reporting action of all channel, common-mode, differential, and function waveforms, use the :LTEST:LLINe:SWAVeform:RESet command.
To turn on limit testing for a limit line test, use the :LTESt:LLINe:TEST:STATe command.
| Argument | Description |
|---|---|
| DISK | Saves the waveform to a file (.wfmx) in the %USER_DATA_DIR%\Limit Lines folder. Use the :LTESt:LLINe:SWAVeform:FUNCtion:FNAMe command to specify the file name. |
| MEMory | Saves the waveform to a memory location. Use the :LTESt:LLINe:SWAVeform:FUNCtion:WMEMory command to specify the memory location. |
| OFF | Turns off the saving of a function waveform. |
Requires FlexDCA revision A.04.50 and above.
Example
This example shows the general steps required to load two limit line tests. One test is for a channel waveform and one test is for a function waveform. Limit testing is applied to each limit line test and both waveforms are saved to a file upon test completion which occurs on the first failed data point. The waveform content window is tiled so that the two waveforms do not overlap. In a real example, you would need to create the limit test for your waveforms and manage the correct positioning of the limit lines.
