We are using the PCGU1000 for our product. We program the PCGU1000 via the DLL to generate a sweep (ie: SetSweep 270000, 370000, 10, 5, 20, 1) and after a while we stop the generator with the StopGen command.
In this state we switch the UI to visible or invisible with the ShowGen(0) or ShowGen(1) command. Then UI appears or disappears the generator ALSO STARTS generating a sweep again!!!
We I did not command it to start the sweep again. This is a BUG!!
OK - you are using a special modified version of the FGU.EXE.
This version is using the old method to check the virtual COM port address.
This version has to be run “As Administrator”.
Now also this version of the FGU.EXE is updated.
