如何根据用户输入连接USB端口

嗨HD，有（至少）2种方法这样做。
对于单个设备而言我所说的“正常”方式是使用VISA别名。
在VEE IO管理器中，您为仪器设置别名（名称） - 它往往默认为new_instrument1等（这是一种耻辱，因为在大多数情况下它可以从仪器中读取很多）。
我建议在进行任何编程之前，将名称更改为有用的内容，例如：
示波器，DSO1234，温度监视器等（较短的名称通常更好）。
（可选）在保存运行时时，请使用该程序取消选中save IO config。
当你把它放在只有运行时的机器上时，使用VEE运行时IO配置（抱歉不能完全记住应用程序名称），找到仪器，设置它的程序别名，一切顺利。
警告现在你已经编程了，如果你想改变VISA别名它有点尴尬，但这可能是另一个帖子的主题;-)另一种方法是动态设置VISA地址，即在程序中。
这仍然使用VISA别名，例如
（再次请原谅可能不准确的语法）DSO1235.IO.VisaAddress =“USB0 :: 1234 :: 9876 :: TW890123456 :: 0 :: INSTR”，其中地址可以通过USB端口和仪器详细信息构建。
如果您有多台仪器执行相同类型的操作，这非常有用。
让我们知道您的身体情况如何！
干杯，迈克

  Hi HD,
There are ( at least ) 2 ways of doing this.  For a single device and what I would say is the 'normal' way of doing this is to use the VISA alias.

In the VEE IO manager, you set an alias ( name ) for the instrument - it tends to default to new_instrument1 or the like ( which is a shame as it can read quite a bit from the instrument in most cases ).  I would recommend that before doing any programming, change the name to something useful e.g. Oscilloscope, DSO1234, temperature_monitor or the like ( shorter name is generally better ).

Optionally, when saving the runtime, uncheck the save IO config with the program.

When you put this on a machine with only runtime, use the VEE Runtime IO Configuration ( sorry can't quite remember the application name ), find the instrument, set its alias as for the program and all's well.

Caveat is that now you've programmed it, if you want to change the VISA alias it's a bit awkward, but that could be the subject of another post ;-)

The other way is to set the VISA address dynamically i.e. in the program.  This still uses the VISA alias though e.g. ( again please excuse the potentially non-exact syntax )
DSO1235.IO.VisaAddress="USB0::1234::9876::TW890123456::0::INSTR"

where the address can be built from USB port and instrument details.

This is really useful where you have multiple instruments doing the same sort of operations.

Let us know how you get on!

Cheers, Mike

截图很有用。
我想你可能有一个简单的拼写错误;-)
