RF Calibration Kit The Bird RF Calibration Kit is meant for operation wherever RF power must be measured at high accuracy and high power levels. Additionally, the sensors may be used as a standard to calibrate general field power sensors. The RF Calibration Kit may be used to calibrate RF radios, wattmeters, directional couplers and other high-power RF test equipment in the field or metrology lab.
Some advanced features are also available through the USB interface, such as modifying the factory calibration. 4421A RF Power Meter The 4421A RF Power Meter is used to display the measurements of the Bird RF Power Sensors in the RF Calibration Kit. The 4421A is equipped with a touchscreen interface.
The power sensors may be connected to a Bird 4421A RF Power Meter or a computer. The Bird 4421A RF Power Meter connects to the sensor using an interface cable that provides a path for serial data communication between the power sensor and the power meter.
