如何使用agilentrfsiggen ivi-com驱动程序执行避免错误查询操作

很抱歉，如果这是错误的发布区域，但我没有看到特定的信号发生器远程控制。我正在尝试使用VS2005 C＃.NET中的AgilentRFSigGen IVI-COM驱动程序来控制我的N5182A MXG信号发生器。
我没有尝试使其符合IVI并且直接调用了安捷伦设备特定的类。我正在尝试使用“ErrorQuery”方法向所有属性集和方法添加错误检查。
手册指出当“QueryInstrumentStatus”设置为True时可以使用此函数，以便在驱动程序检测到仪器错误时检索错误详细信息。我已将此标志设置为true，但令我困惑的是错误实际上是如何获得的
查询或报告。
即：ErrorQuery方法什么都不返回，并声明您需要传递ErrorCode和Instrument错误消息。
???
这种方法到底是做什么的？
我原本以为“ErrorQuery”正在查询错误，因为我习惯于查询返回Void以外的东西。“QueryInstrumentStatus”会导致命令抛出异常或其他东西吗？如果有人可以给我一只手勾勒出哪些命令
我会做完设置一个值或运行一个方法，然后进行错误检查，这对我来说会有很长的路要走。
我试图避免添加第二个类来包装所有驱动程序命令以添加错误检查.Thx。

  Sorry if this is the wrong posting area but I didn't see a specific one for Remote Control of Signal Generators.
I'm trying to control my N5182A MXG Signal Generator using the AgilentRFSigGen IVI-COM driver within VS2005 C#.NET.  I'm not attempting to make it IVI compliant and have just made a direct call to the Agilent device specific class.
I'm trying to add error checking to all the property sets, and methods by using the "ErrorQuery" method.  The manual states that this function can be used when the "QueryInstrumentStatus" is set to True, to retrieve error details when the driver detects an instrument error.

I have set this flag to true, but what has me baffled is how the error actually gets queried or reported. ie: The ErrorQuery method returns nothing, and states you need to pass in the ErrorCode and Instrument error message.  ??? What exactly does this method do then? I would have thought the "ErrorQuery" is querying the error since I'm used to Queries returning something other than Void.
Does the "QueryInstrumentStatus" cause the commands to throw an exception or something?

If someone could give me a hand outlining which commands I would do to accomplish setting a value or running a method and doing error checking after, it would go a long way for me.  I'm trying to avoid adding a second Class to wrap up all the Driver commands to add error checking.
Thx.
