scope SCPI did scope single trigger occur?

Two questions:&#160;<br> <br> 1. Is there a way to use SCPI to keep polling if my single trigger has occured yet? What I'm trying to do is to keep raising a threshold voltage until it triggers so I can take a screen shot.&#160;<br> <br> 2. I'm noticing that I'm not able to use SCPI routine to take a screen shot until the single trigger happen. Is this expected? Technically, I should be able to take a blank screenshot without any traces showing albeit not very informational.&#160;

These commands can be found in the Act on Event Command group.</span></span></span></span><br> <span style="font-size:12pt;"><span style="font-family:&quot;Times New Roman&quot;,serif;">&#160;</span></span><br> <span style="font-size:12pt;"><span style="font-family:&quot;Times New Roman&quot;,serif;"><span style="font-size:9.0pt;"><span style="font-family:&quot;Segoe UI&quot;,sans-serif;">2) You should be able to just take a blank screenshot with SAVe:IMAGe, but it may be because you have some other settings turned on. Could you try running this command before doing a SAVe:IMAGe command?</span></span></span></span><br> <span style="font-size:12pt;"><span style="font-family:&quot;Times New Roman&quot;,serif;">&#160;</span></span><br> <span style="font-size:12pt;"><span style="font-family:&quot;Times New Roman&quot;,serif;"><span style="font-size:9.0pt;"><span style="font-family:&quot;Segoe UI&quot;,sans-serif;">ACTONEVent:TRIGger:ACTION:SAVEIMAGe:STATE 0</span></span></span></span><br> <span style="font-size:12pt;"><span style="font-family:&quot;Times New Roman&quot;,serif;">&#160;</span></span><br> <span style="font-size:12pt;"><span style="font-family:&quot;Times New Roman&quot;,serif;"><span style="font-size:9.0pt;"><span style="font-family:&quot;Segoe UI&quot;,sans-serif;">Best,<br> Iris Xu</span></span></span></span><br> &#160;
