Measuring and Monitoring RF Power
The Models 8578A100, 8578B100, 8578A150, and 8578B150 Load Resistors
may be used in conjunction with any one of the various Bird rigid coaxial line
Thruline
®
Wattmeters. When fitted with the appropriate line section and
wattmeter, either model becomes a useful tool for tuning and adjusting a
transmitter as well as monitoring RF power directly in watts. Call a Bird
Sales office for more information about Thruline wattmeters. See “Customer
Service” on page 19.
WARNING
Do not touch the surface of the load. The surface may become hot when
