Directional RF Thruline® Wattmeter, Series 4410
5
Inserting in Transmission Line
WARNING
Exposure to RF power radiation and the possibility of RF shock or burns exist
under some operating conditions. Always turn off transmitter when
connecting or disconnecting wattmeter. Be sure transmission line is
terminated into a load or antenna. When plug-in element is removed from
the RF line socket, the line section center conductor is exposed. Do not put
fingers or other objects into the plug-in element socket while RF power is
applied.
Insert the Series 4410 Thruline Wattmeter in coaxial transmission lines of 50
ohms nominal impedance. It makes no difference which side of the wattmeter
the power source and the load connections are made. Use a coaxial
transmission line fitted with suitable matching RF connectors. If cables of other
than 50 ohms impedance are used, a mismatch will occur which could cause
serious inaccuracies in the readings.
