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

power is applied to load.
