BIRD 4480A Features and Specifications *
The Bird 4480A Wattmeter is an advanced RF power measurement device designed for professionals who require high precision, reliability, and versatility in their radio frequency (RF) power monitoring applications. Engineered with an element-free design, this wattmeter eliminates the need for separate elements, streamlining the measurement process across multiple frequency bands. Covering a broad frequency range from 2 MHz to 1000 MHz, the unit ensures accurate readings for both Continuous Wave (CW) and digitally modulated signals, making it a valuable tool for telecommunications, broadcasting, industrial RF systems, research, and military applications. One of the standout features of this RF wattmeter is its ability to provide true average power measurements, ensuring precision in evaluating RF power levels. Unlike traditional wattmeters that require different elements for varying frequency ranges, this unit simplifies operations by accommodating low-band frequencies from 2 MHz to 30 MHz and high-band frequencies from 25 MHz to 1000 MHz. This versatility eliminates the hassle of managing multiple elements and enhances efficiency in testing environments. The device offers high power handling capabilities, supporting measurements up to 10,000 Watts in the low-band range and up to 1,000 Watts in the high-band range. This feature makes the Bird 4480A particularly suitable for high-power applications where precision is critical. Its ±4% accuracy (±0.18 dB) ensures that readings are reliable and meet the stringent demands of RF professionals. Beyond basic power measurement, this provides comprehensive RF diagnostics, including Forward Power, Reflected Power, Voltage Standing Wave Ratio (VSWR), and Return Loss (RL). These features enable users to assess system performance, detect mismatches, and optimize RF transmission efficiency. The wattmeter's ability to toggle between Watts and dBm further enhances its adaptability, allowing users to choose the preferred unit of measurement based on their specific requirements. The device’s Peak to Average Ratio (PAR) capability extends up to 10 dB max, making it useful for analyzing signal quality in various transmission environments. This function is essential in applications such as broadcasting and military communications, where signal integrity is paramount. A key advantage of the Bird 4480A Wattmeter is its intuitive three-button interface, which simplifies operation even in demanding conditions. Users can quickly access essential functions such as backlight control, unit switching between Watts and dBm, and high/low band selection. The unit is also equipped with a 240x128 pixel backlit LCD display, ensuring clear visibility of measurements in low-light environments or outdoor settings. Another valuable feature is the integrated battery life indicator, which provides real-time monitoring of power levels, ensuring that the device remains operational when needed. The internal NiMH 6-AA battery pack supports a minimum operating time of 8-10 hours, with a recharge time of 6-8 hours, providing sustained usability in field operations.
Built for rugged use, the unit complies with MIL-PRF-28800 Class 3 standards, ensuring durability and reliability in harsh conditions. It holds certifications including CE, RoHS, and UKCA, affirming its adherence to international safety and environmental standards. The wattmeter’s operating temperature range of 0°C to 50°C (32°F to 122°F) and storage temperature tolerance from -40°C to 71°C (-40°F to 159.8°F) make it suitable for various climatic conditions, including extreme environments. The unit is also designed with Quick Change (QC) RF connectors, allowing users to swiftly swap connectors without additional tools. This feature enhances flexibility, making the Bird 4480A compatible with different radio types and transmission setups. The Bird 4480A Wattmeter is widely used in multiple industries due to its high accuracy and broad frequency range. In telecommunications, it ensures optimal performance in cellular networks, satellite communications, and Wi-Fi systems, providing precise power measurements that contribute to improved signal quality. Broadcasting professionals rely on the wattmeter to maintain signal integrity in radio and television transmission, preventing issues such as interference and power mismatches. The device also plays a crucial role in military and aerospace applications, where reliable RF measurements are essential for tactical and strategic communication systems, radar operations, and avionics testing. Additionally, industrial RF systems, research institutions, and test laboratories benefit from the Bird 4480A for its accuracy and ability to handle high-power RF applications. The wattmeter operates on a DC 12V, 2A power supply, with a maximum draw of 0.6A. It also features an input attenuator range of 0 to 30 dB in 1 dB steps, allowing precise attenuation adjustments when needed. To maintain its accuracy, the device requires a recommended calibration interval of 12 months, ensuring continued precision over extended periods of use. This comes with essential accessories, including a standard power cord (4421-055) and a 110/220V AC charger (4480A152). Optional accessories include a rugged transit case (4480A046) for added protection, an international power cord (5A2416UK) for global compatibility, and a battery replacement kit (RPK7000-2) for extended service life.
