I was using VSG25A with 0dBm output power in CW mode, there was a load connected to generator, but suddenly connenction with device with device was lost and now when I plug the USB, coputer says “usb device is malfunctioned” and it is same on three different computers. Could anyone suggest what is possible to do to fix it.
I have not seen this problem before, but your VSG should still be covered under warranty. Contact support@signalhound.com and we can set up an RMA for repair. I apologize for the inconvenience. If you bought it from a distributor, contact them for a repair or replacement unit.
