How to check the S.W.R. of your Antenna :

• ​Connect to "TX" on Radio output  and Antenna  to "ANT".  Proper adaptor/cable is required if your device has different type of connectors.

1. Measurement V.S.W.R. : (see Pic.1)
2. SW-102 TX connect Radio RF out  
3. Radio TX , SW-102 with display S.W.R. measure data.
   Do not affect the test in the following cases, there are objects nearby, placed horizontally.

How to check the output Watt of your transceiver :

1. Connect to "TX" on Radio output and dummy Load to "ANT".  Proper adaptor/cable is required if your device has different type of connectors.

1. Measurement Power: (see Pic.2)
2. SW-102 TX connect Radio RF out  
3. SW-102 ANT connect 50 ohm Dummy Load
4. Push Radio TX , SW-102 display is Power  measure data.
