I am trying to control PNA with VDI extension module by LabVIEW. Because the PNA frequency range is below 50 GHz in my lab, So I connected PNA with VDI extension module to extend the frequency at the range of 120 GHz --150 GHz approximately. And When I ran the LabVIEW code to get test result, I got an error named "out of range", So I checked the driver which I choose the Keysight Driver, I found that the frequency limit of Keysight Driver is just 30 GHz approximately, and I changed the frequency range up to 150 GHz, after that I tried again, But it did not work, I still got the error. after that I also changed to NI Driver but still not work. I just have no idea what's going on with my code. Technically speaking, the PNA should detect the VDI extension module and change the frequency range automatically, when I connect PNA with VDI. I also attached the code both Keysight code and NI code
