Timeout error on Agilent

[rcarr]

I am trying to communicate with my Agilent 35670A through the GPIB. I am trying to do a swept sine mode. Once the application starts I get the Timed-out Error just before the port closes. Both the vi and a screen shot of the error is included. Am I missing something? Thanks in advance for your help.

Hello rcarr,

        I am glad to see that you are using the LabVIEW Plug and Play (project-style) Instrument Driver for your instrument.  Thank you for posting your VI and a screenshot of the error.  It appears that you might be using the "Actn Start Stop Cont" VI incorrectly. 

Please take a look at the examples that are included with the instrument driver and see how they are implemented.  Also, please turn on Context Help (ctrl-H) and hover over the VIs to see more information about how they should be used.

Thanks,

NathanT

Thank you for getting back to me. I have looked over the examples. They all however use the trigger, a setting which is not recognized by the swept sine mode. I reconfigured my VI with the start OPC, then the RUN STOP and finally the wait OPC. I am still getting the error. I can't figure out what I'm doing wrong.

Hello rcarr,

       The timeout error occuring in the Wait for RQS seems to show that the instrument driver is waiting for the instrument to send a service request (and that it is not being sent in the allotted amount of time).  Thank you for attaching your VI.  I think that you should try enabling the "Bus Trig Or Arm" control in the "Actn Start Stop Cont" VI.  If that does not take care of the issue, I recommend looking through the instrument's manual and looking for the correct order of operations for a swept sine measurement.

Cheers,
