RSA 306B Software Error

I am having an issue with the software received with my RSA306B. After purchasing the unit, I tried downloading the software that came with the device, it gave me an error saying it was a 30-day trial and could no longer be downloaded. However I never used the software and was unaware it was a trial, but if that is correct, what other free software could I use to view the signal off of the RSA306B remotely?

The RSA306B is designed to connect to SignalVu-PC which is available as a free download from here: https://www.tek.com/en/support/software/application/signalvupc-vector-signal-analysis-software-v450093

There are several paid software options for SignalVu-PC that expand its functionality and offer free 30 day trials but the base software is free. The datasheet elaborates more on these features here: https://www.tek.com/en/datasheet/vector-and-rf-suite-signal-analysis-software-pc
