关于.NET Ref在teststand 中的传递——————急

[JAC_HU]

N4010测试WLAN产品，采用Labvie+teststand平台，在一个Labview VI中调用Agilent .net driver 打开仪器 并将该动作产生的Reference 传递到一个全局变量中，再在下一个VI中调用该Reference直接测量，每次都有出错。但是若在同一VI中执行打开仪器再测量就没问题。请问，该如何将Reference传递到下一个子VI？附上图，

N4010 testing WLAN products, using Labview + teststand platform, in a Labview VI called Agilent. Net driver to open equipment and that the action generated by Reference delivered to a global variable, then the next one VI to call the Reference direct measurement, each has an error. However, if in the same VI in the implementation of the measure no problem re-open the instrument. I ask, how to pass to the next Reference a sub-VI? Attachedimages
