Data Sheet 4530 RF Power Meter Taking performance to a new peak 4530 Series RF Power Meters: Accuracy & Speed for Production Test Boonton’s 4530 Series RF power meters combine the accuracy of a laboratory-grade instrument with the speed required for production test. They employ proprietary measurement techniques that accurately measure digitally-modulated signals. Whether you’re measuring CW power or the peak power of w-cdma or hdtv signals, Boonton’s single-channel Model 4531 and dual-channel Model 4532 are the logical choice for highvolume production test. More Than Power Alone 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 a wide variety of Boonton RF power and voltage sensors, from coaxial dual-diode types, to thermal sensors, for measurements Features 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 nonlinearities 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. • Peak Power • Frequency Range: 50 MHz To 40 GHz • Dynamic Range: >60 dB • Bandwidth: 20 MHz • CW Power • Frequency Range: 10 kHz To 40 GHz • Dynamic Range: 90 dB Future Perfect The 4530 measures the precise peak and average power of For cdma or other spread-spectrum signals, the 4530’s statisti- today’s complex digitally-modulated carriers.

That means you’ll never know how an amplifier you can perform time-gated or power-gated peak and average will perform in the field when driven into compression by these power measurements as well.

And with its wide video bandwidth, the 4530 detects even narrow peaks. 2 The 4530’s dual-processor architecture enables comprehensive And Boonton’s exclusive peak tracking mode allows short term measurements with high speed and performance.
