I am gettin an error with LV7 using the agpna instrument driver to talk to a E8364A 50GHz PNA. The error on the PNA says something like "error 420, query unterminated" and then the VI times out and fails to capture data. Does anyone know how to properly terminate the query for the PNA?
Make sure you have the latest version of VISA and 488.2. You can obtain these from our web site. http://digital.ni.com/softlib.nsf/954feaeea92d90918625674b00658b83/3d536368faf409a086256d3400650632?OpenDocument http://digital.ni.com/softlib.nsf/954feaeea92d90918625674b00658b83/7e177d6e06db36b886256d720078da05?OpenDocument
I would suggest trying to run the example and the self-test that are included with the instrument driver to verify that the driver is working correctly.
Joshua, i found out what the problem was. it was with the e8364a firmware. i was using an older version. After updating to the latest firmware, the instrument driver runs now without any errors or warnings. Thanx Deji
