Reply To: TG44A (Device not found) strange behavior

Hi Luigi,

Thanks for contacting us.

I’m not sure I’m following everything…it actually sounds like both devices are working. Is the TG not producing a signal?

The TG will not show up in the File > Connect menu, that is only used for spec ans. If the TG is connected, its LED should be green. In Spike, the TG is accessed in two ways: through Utilities > Tracking Generator Controls (which will add a subsection to the left-hand control panel). If the TG is not connected, an error dialog will appear that says “Tracking generator not found…” The other way is by entering scalar network analysis mode via Analysis Mode > Scalar Network Analysis. If the tracking generator is not connected, this option will be greyed out.

When the TG standalone app is opened, it will attempt to connect with the device, and a dialog will say “Connecting device…”. If it is not successful, a dialog will be displayed that says “Error connecting device.”

Please note that you cannot have Spike and the TG standalone software running simultaneously, so make sure that you shut one down before using the other.

Are any of these error dialogs appearing? Is the Scalar Network Analysis Mode available or greyed out? Most importantly, is the TG producing a signal? My apologies if I missed that in your email, I didn’t see any information about whether or not it was generating a signal.

I look forward to your response.
