Query Interrupted error on 4287

I am trying to *TRG a table of frequencies on a 4287 analyzer and no matter what I do if I am stepping through the code, or running it.  Any command I send to the analyzer after the *TRG results in a "query interrupted" error on the display, including an *OPC? or a ReadStatusByte.  When stepping through the code I wait until the analyzer if very obviously done with the command and I still get the error.

Not sure what a 4287 is.

Seeing your code would help.
