Used BIRD 4421 #293820006 for sale

BIRD 4421 is an electronic test equipment designed to measure the power of a wide variety of RF devices. It utilizes a wattmeter to accurately measure the peak output of any RF device, ranging from radar antennas to Wi-Fi access points. 4421 offers two modes of operation—peak-power and true-power measurement. In peak-power mode, the meter measures the device's peak output power for a specified duration, with fast update rate. The true-power mode measures the average power in a specific frequency range, over a user-defined interval. This feature is particularly useful in testing emerging wireless technologies that utilize multiple frequency bands in the same device. Additionally, BIRD 4421 features digital signal filtering that allows the meter to accurately measure the signal power of varying frequencies and signal types. 4421 incorporates several advanced safety features including isolated port protection, returning it to a safe reference input voltage when an antenna is connected to the unit. This ensures that it remains safe and protects any connected antennas from damage. Furthermore, BIRD 4421 features a zero insertion force port that eliminates the need for connectors with precise mating positions. The RF connectors are made from high quality materials and ensure a low voltage drop to ensure minimum power loss. Additionally, 4421 features a built-in display to view the RF power readings. BIRD 4421 is designed to be extremely rugged. It can withstand extended periods of usage and abuse, and has been designed to sustain extreme temperatures, ranging from -20°C (-4°F) to 60°C (140°F). It also has dielectric strength of up to 10kV/m, making it immune to external noise and ambient electric fields. The high strength aluminum housing also ensures environmental protection, while the vibration-proofing rubber strips keep it firmly in place, even during long tests. Overall, 4421 is an excellent option for RF engineers and technicians who are looking to accurately measure the power of their RF devices. Its advanced safety features, high accuracy measurements, and robust design make it an ideal choice for any application.
