具有单个外部触发的连续扫描列表

使用N5183A和e8257d进行这些试验，我发现无法设置我想要的场景。
我想创建一个最初在外部触发的扫描列表，但在第一次触发后，让扫描列表连续运行。
在连续模式下扫描和为ext设置触发器的当前设置具有扫描保持，直到完成列表后的下一个触发。
我已经尝试在扫描开始后将触发器从ext切换到自由运行但是会中断扫描并重新启动它不再与初始ext触发器同步。
我的列表正好持续1秒，外部触发器是1PPS脉冲。
不幸的是，看起来ext触发器的监视器在列表完成后需要某种保持时间才能重新触发。
我的列表正好是1秒，没有保持时间，源将错过下一个1PPS并等待下一个重新触发。
所以它目前每隔一秒输出一次，而不是连续输出。
我发现缩短列表使得它在第二个结束之前的100ms的顺序完成足够的时间让源重新设置以寻找ext触发器。
然而，通过降低100毫秒，我不再获得我想要的扫描列表。
有关设置以获得最初触发的连续扫描的任何建议吗？
谢谢。

  Using a N5183A and an e8257d for these trials I have found no way to setup the scenario I desire.

I would like to create a sweep list that is initially triggered externally but after that first trigger, have the sweep list continuously run.  Current setup with sweep in continuous mode and trigger set for ext has the sweep hold until the next trigger after it completes the list.

I have tried switching the trigger from ext to free run after the sweep has started but that interrupts the sweep and restarts it no longer synchronized to that initial ext trigger.

My list lasts exactly 1 sec and the external trigger is a 1PPS pulse.  Unfortunately, it looks like the monitor of the ext trigger needs some kind of hold time after the list finishes in order to retrigger.  With my list being exactly 1 sec, there is no hold time and the source will miss the next 1PPS and wait for the following one to retrigger.  So it currently outputs every other second, instead of continuously. I have found shortening the list such that it completes on the order of 100ms prior to the end of the second is enough time for the source to re-ARM to look for the ext trigger.  However, by dropping the 100ms I'm no longer getting the sweep list I desire.

Any suggestion on set up to get a continuous sweep that is initially triggered?

Thank you.
