THE 4530 SERIES RF POWER METERS: ACCURACY AND
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, faster, than any other
RF power meters on the market. So 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 high-volume 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 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 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.

FUTURE PERFECT

The 4530 measures the precise peak and
average power of today’s complex
digitally-modulated carriers...and
those of tomorrow as well.
Modulation bandwidths up to
20 MHz are within the range of
the 4530, which makes it the
best choice for measuring CDMA,
W-CDMA, CDMA2000, TDMA, GSM, GSM-EDGE, GPRS, OFDM,
HDTV, and UMTS with the flexibility to accommodate new modulation
schemes in the future. The 4530 displays periodic and pulse
waveforms in graphical format, and a host of automatic
measurements characterize the time and power profiles of the pulse.
Powerful triggering, effective sampling rates up to 50 MSamples/sec.
and programmable cursors give you instantaneous power

measurements at precise time delays from the pulse edge. With an
internal or external trigger you can perform time-gated or power-gated
peak and average power measurements as well. Triggering can be
synchronous or asynchronous. Display can be adjusted to pre-trigger
or post-trigger to view any portion of the waveform.

For CDMA or other spread-spectrum signals, the 4530’s powerful
statistical analysis mode allows full profiling of power probability at
all signal levels. The 4530 makes even these complex measurements
fast, thanks to sustained acquisition rates above 1 MSample/sec. and
smooth, range-free operation that allows a representative population
to be acquired and analyzed rapidly.

RELIEF FOR AMPLIFIER DESIGNERS

The random and infrequent nature of power peaks makes them
almost impossible to detect and measure with conventional power
meters. That means you’ll never know how an amplifier will perform in
the field when driven into compression by these fleeting peaks–until
it’s too late. The 4530 gives you this critical information by analyzing
the probability-of-occurrence near the point of absolute peak power,
then detecting and analyzing the data with the high accuracy
required to realistically evaluate an amplifier’s performance. And with
its extremely wide video bandwidth, the 4530 detects even the
narrowest peaks.

The 4530’s powerful dual-processor architecture enables

comprehensive measurements with unprecedented

speed and performance. It eliminates the speed

tradeoffs between data acquisition and output

via GPIB that are a fact of life with other power

meters. A high-speed, floating-point digital

signal processor (DSP) performs the

measurements, gathers and processes the

power samples from the sensors, time­stamps the measurements, and provides

linearity correction, gain adjustment and

filtering—all in less than a microsecond.

The processed measurements are then passed to a dedicated,
32-bit I/O processor that sends them to the LCD display and over
RS-232 or GPIB interfaces when formatted measurements are
required. Programming is easier as well, thanks to comprehensive
use of the industry standard SCPI command syntax.
