Hi ANguyen,
Thanks for the details provided.
The error is -8: Device Not Found. The error codes can be looked up in the API docs.
Is the SA44B working in Spike? If so, make sure Spike is not running when attempting to connect in LabVIEW. If not, it would be best to troubleshoot that first.
Note that the USB driver needs to be installed separately. It can be downloaded with this link. Unplug devices, right click on the driver and select “Run as administrator”. Then plug in device and run Spike.
If you are not able to get the SA44B running in Spike, please reach out to support@signalhound.com for more detailed troubleshooting.
