The signal generator is the Agilent (33120A)

But VI execution to half Shique the following error window

Hi

Noticed that you are using serial port to communicate to instrument. Would you please double-check the serial setting parameters, such as Baud Rate, Flow Controls and etc. are insistent with the configuration on instrument? Or would you please try to use other interface rather than serial port.

If you have tried everything I mentioned above and it still raised that error, please manipulate the NI I/O Trace (You could find it in Windows Start menu) tool to trace and log the communication between PC and instrument. I should be helpful to analyze the root course if you investigate into that trace log. It would be great if you post it here!

Thanks,

- Charles

A query interrupted message comes from the machine itself so probably nthing is wrong with the communication but you started a second query before the first one was finished. So check for end characters more than baudrate.

HI,

I check my baudrate is accurate(9600)

HI,

i check

serial port , Baud Rate(9600) , Flow control , parity   are all correct

However, I found a strange thing
I run this vi several times
Will not appear on the error message, and do not know why?  = =lll

try  another computer.

What about using NI I/O Trace to get the trace information?

Thanks all~

I have been solve this question,

I modify this vi , and then it can work.

Did you modify the end characters? I'm getting the exact same error.

The tread ended but nobody posted the solution.
