PCGU1000 ShowGEN BUG when using sweeps


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!!

We use the latest FGULink.DLL

Please correct this issue and reply.

Best regards,

Thank you for the feedback.
I’m sorry for the inconvenience.
The issue is now fixed.
Here is the link to download updated FGU.EXE:

Unfortunately the FGU.exe you placed online does not set or does not generate a sweep in combination with the FGUlink.dll we use!

We use the set from former link: box.net/shared/1q8m2nqnav41acd5urhj
This set includes the extra option of sweeping a library waveform.

Please correct the FGU.exe from this set.

Awaiting your reply,


OK - you are using a special modified version of the FGU.EXE.
Ref. viewtopic.php?f=11&t=6562
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.
Here is the download link:

Thanks, this one works fine for us!
