Re: QMX (1_00_020) SWR - Issue?
|
- VNA comes with SMA and QMX with BNC. So you use at least one additional adapter. Could you tell how the antenna cable is connected in each case?
- BNC connectors are reliable. But in rare cases contacts maybe out of shape producing bad connections.
- I'm not sure about the frequency accuracy of the used VNA. Afaik you could use a VNA as a generator for single frequencies. So you may set the VNA on a frequency in the 20 m band and receive with your QMX. Is there a difference? Please don't connect both! Put each device away from the other. Don't connect an antenna to the QMX. An open BNC should be ok.
- You should really look for a dummy load.
