100 W to 250 kW, Single Carrier RF Power Monitor
The 3127A Wattcher RF Power Monitor/Alarm is designed to protect and monitor your RF frequency transmission system by connecting the power meter to a Bird dual port thruline line section and two elements compatible with the RF coaxial line.
The elements are selected by the user to cover the desired power levels and frequency ranges. Purpose and Function Abnormal loading conditions cause the transmitter to quickly shutdown, a user selectable audible alarm to sound, and an alarm LED to flash. Remote access is available for resetting audible and visual alarms. Fail-safe or non fail-safe modes are user selectable and the reflected power trip level is adjustable.
