How to check the S.W.R. of your Antenna :
Connect to "TX" on Radio output and Antenna to "ANT". Proper adapter /cable is required if your device has different type of connectors.
Measurement V.S.W.R. : (see Pic.1)
SW-102 TX connect Radio RF out
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 transceiver RF output Watt :
Cable Connect to "TX" on Radio output and dummy Load to "ANT". Proper adapter /cable is required if your device has different type of connectors.
Measurement Power: (see Pic.2)
SW-102 TX connect Radio RF out
SW-102 ANT connect 50 ohm Dummy Load
Push Radio TX , SW-102 display is Power measure data.
(SW-102 is not for D.M.R. system)
How to display rotate : (up to Ver. 2.02 only )
Press Yellow key to rotate display in 180 degree ,
Press Yellow key to normal .
