Getting error message while I try to use VI to control DS 360 fucntion generator

[amit54]

My PC to connected to the function generator through GPIB and I am  trying to change the frequency of DS 360 function generator from labview VI. It was working fine but I am not sure what went wrong in the VI, now every time I run the VI an error message appears.

I am using the VI that is included in the DS360 driver. The error is actually in the GPIB send message.vi. It says "*ESR?4".

I think something is wrong in  sending the command from labview to the function generator but I am not able to figure out what is that exactly.

Any kind of help is highly appreciated.

Thanks

What is the full text of error? I doubt that it is just "*ESR?4"... And if so, then this is driver-related error code - did you check some manual or documentation for the generator/its drivers?

Thanks,
