The 4530 is more than a simple RF power meter. It measures CW power, peak power, voltage, and performs statistical power analysis (CDF and PDF) as well. The 4530 is compatible with all Boonton RF power and voltage sensors too, from coaxial dual-diode types, to thermal sensors, for measurements up to 40 GHz. Sensor set-up is easy and accurate too, since calibration and set-up data are automatically downloaded from the sensor, as soon as it?s plugged in. The 4530 provides seamless CW power measurement over its broad dynamic range?without the interruptions and non-linearities caused by range changes required by lesser power meters. Our thermal and peak-power sensors never need range switching, and even our CW diode sensors?with 90 dB dynamic range?use only two widely overlapping ranges.
