Use the steps below or watch the embedded video to troubleshoot your VNA connection.

First, make sure that the VNA is powered ON and the USB cable is connected to both your VNA and your PC.

Next, launch the VNA software and make sure that it is not in Demo Mode. To check this, use the following softkeys – System > Misc Setup > Demo Mode > OFF.

The bottom right corner of the software reads the status of the device. This usually reads as either “Ready” or “Not Ready”. If the status says “Ready”, you can go ahead with your measurements.

However, if the status reads as “Not Ready”, there are a few ways to determine the cause:

1. Make sure that you are using the latest version of our software. To check the software version on your software, click on System -> About. If your software is out of date, you can download the latest version from our website coppermountaintech.com/download-the-software.
2. The next step is to Power Cycle the VNA and see if the status then changes to “Ready”. If you are unable to establish connection, continue performing the next steps.
3. Open the Device Manager in your PC and scroll down to “Universal Serial Bus Controllers”. Now, expand the drop down menu and check if your VNA is listed under this menu.
4. If your VNA is not listed under “Universal Serial Bus Controllers”, try using a different USB cable and then check the menu again.
5. If you are using a USB HUB and replacing the USB cable did not resolve the issue, try connecting your USB directly to your computer bypassing the hub.
6. Lastly, try connecting the VNA to a different computer, as some PC settings could be the cause of the connection issues.
