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.
