Description:
RF Power Meter
Information
The 4530 Series RF Power Meter is a new generation of
instruments. It allows high-resolution power measurement ofa
wide range of CW and modulated RF signals over a dynamic
range of up to 90dB depending on sensor. The powermeter is
available configured as the single-channel Model 4531
or as
the dual-channel Model 4532, For the remainderof this
manual, the series designation of 4530 will be used to
indicate either model, except when otherwise stated.
The 4530 is really several instruments in one, and can
function as a CW Power Meter, a Peak Power Meter, a
StatisticalPower Analyzer, and an RF Voltmeter. It accepts
the full series of Boonton RF power and voltage sensors,
whichincludes coaxial dual-diode sensors and thermal
sensors. Sensor data and calibration information is
automaticallydownloaded from the sensor or “smart adapter”
whenever a new sensor is connected, eliminating the need to
manuallyenter calibration factors.
When used as a CW power meter, the 4530 provides seamless
measurement performance due to the extremely widedynamic
range of its input stage. Thermal and peak power sensors
require no range switching under any conditions,and even CW
diode sensors spanning a 90dB dynamic range require only two
widely overlapping ranges. This meansthat practically any
measurement can be performed without the interruptions and
non-linearities associated with therange changes of
conventional power meters.

For modulated signals, the 4530 can make accurate average
and peak power measurements with modulation band-widths as
high as 20MHz, making it ideal for high-speed digitally
modulated carriers such as CDMA, W-CDMA, GSM,TDMA, HDTV and
UMT. Periodic and pulse waveforms can be displayed in
graphical format, and a host of automaticmeasurements are
available which characterize the time and power profiles of
the pulse. Effective sampling rates up to50MSa/sec and user
programmable cursors allow instantaneous power measurements
at precise time delays from thepulse edge or an external
trigger as well as time gated or power gated peak and
average power.
For spread-spectrum or randomly modulated signals such as
CDMA, the 4530’s powerful statistical analysis modeallows
full profiling of the power probability at all signal
levels. Sustained acquisition rates in excess of one
millionreadings per second along with rangeless operation
insure that a representative population can be acquired
andanalyzed in minimum time. By analyzing the probability of
occurrence of power levels approaching the absolute
peakpower, it is possible to characterize the occasional
power peaks that result in Amplifier compression and data
errors.Because of the random and very infrequent nature of
these events, they are next to impossible to spot with
theconventional techniques used in other universal power
meters. In addition, the instrument’s extremely wide
videobandwidth insures that even the fastest peaks will be
accurately measured.
The 4530’s powerful dual-processor architecture permits
advanced measurement capabilities with unprecedentedspeed
and performance. A high-speed, floating-point digital signal
processor (DSP) performs the measurements. Itgathers and
processes the power samples from the sensors, performs
time-stamping, linearity correction, gain adjust-ment and
filtering, all in fractions of a microsecond. The processed
measurements are then passed to a dedicated,32-bit I/O
processor that monitors the keyboard, updates the LCD
display and responds to RS-232 and GPIB requestsfor
formatted measurements. This design eliminates the speed
tradeoffs between measurement data input (acquisition)and
output (over the GPIB) that are so common among other power
meters.
Instrument operating firmware is stored in flash memory that
may be field reprogrammed with any PC via the onboardRS-232
port. Free firmware upgrades permit the easy addition of new
features or capabilities that may become availablein the
future. Visit the Boonton website at WWW.BOONTON.COM for
upgrade information and to download thelatest firmware version.
FEATURES
Multi-mode capabilityUtilizes CW sensors, Peak Power sensors
and Voltage probes with automatic sens-ing and setup for
each type. Measures conventional CW power and voltage,power
versus time for pulse analysis, and statistical power
distributions for spreadspectrum signals.
Text and GraphicsThe backlit LCD display shows numerical
results as well as graphical results for allmeasurements.
Measurements are displayed using a large, easy-to-read
numericalformat, or in graph mode with a fast-updating,
oscilloscope-like trace. Dual Independent Channels
ChannelsModel 4532 is equipped with two identical
independent measurement channelswith the capability to
display two pulse measurements, two statistical
measure-ments or two CW measurements at the same time.
Remote ProgrammingAll functions except power on/off can be
controlled by a GPIB Interface or via anRS-232 serial
connection. The programming language follows the SCPI model
withadded non-SCPI commands for special applications.
