MDO3000 Hangs when changing trigger mode

<p>Working with a MDO3054, I have the trigger mode set to 'Edge'.&lt;br&gt; At this moment I have D0 as trigger. Then I decide to change it to &amp;quot;Video&amp;quot; on channel 1. While still having D0 as trigger input,&#160;I press trigger Menu and Type button.&lt;br&gt; I rotate the 'a' control knob until it reaches 'Timeout' option (although i wanted to go further to Video). I cannot go down beyond 'Timeut'; it hangs there! The scope does not respond to any action beyond this point.&lt;br&gt; No way to recover other than restarting the scope.&amp;#160; if I change input channel to CH1(or any other non digital) before selecting the Trigger mode, the problem does not occur.&#160;&lt;br&gt; Firmware version: 1.30 (it happened also with firmware 1.26)&lt;br&gt; &lt;br&gt; Is this a known 'feature'? :-(&lt;br&gt; &lt;br&gt; &lt;br&gt; &lt;br&gt; &lt;br&gt; &lt;br&gt; &lt;br&gt; &amp;#160;</p>

The Video trigger requires an analog source, as you know.&#160; I have not been able to duplicate this issue.&#160; If I start with a default setup, and change the Edge trigger source to D0, and then rotate the trigger type to Video, the Source changes to the highest analog channel number (4).&#160; I am running 1.30 on an MDO3104.

Sure, I know the video is not suitable for digital, but the problem occurs just&#160; because I set the trigger mode *before* I change the input channel. This should not happen. In my case the source does not change by itself when I rotate the wheel, it stays at D0. It is interesting that you see your input source changing automatically.<br> I can reproduce the problem systematically, it always hangs.&#160;<br> <br> It is interesting that this is fixed on MDO3104. It might seem something related to firmware, but apparently it is not.<br> Thanks for your comments.<br> &#160;

FYI, the problem is solved by entering again the options key.&#160;
