4400A RF Peak Power Meter
The Boonton Model 4400A is the
instrument of choice for viewing and
analyzing RF power in the time domain.
Whether you are analyzing radar, pulse
bursts, GSM or TDMA wireless signals,
broadcast TV and radio transmitters, or
any RF signal in which the powerversus-time relationship must be
accurately measured and recorded, the
Model 4400A is the instrument for you.

Flexible triggering, greater than
60-dB dynamic range (sensor dependent) without any range switching, channel math on
active and reference (saved) traces, and Boonton’s wide selection of Peak Power Sensors
round out the Model 4400A’s industry-leading capabilities.
4500A RF Peak Power Meter/Analyzer
For analyzing RF signals with digital modulation, multiple carriers or today’s complex
coding techniques, the Boonton Model 4500A yields the answers that designers and
manufacturers of state-of-the-art wireless communications systems demand. Hard-tomeasure HDTV and spread-spectrum signals like CDMA and WCDMA are now easy to
view and analyze, thanks to the innovative capabilities of the Model 4500A.
Along with all the time-domain measurements of Boonton’s Model 4400A, the Model
4500A adds a host of statistical measurements that are made on a continuously sampled
RF signal. Adding the second input channel to these capabilities allows you to monitor two
sources, such as input and output power, simultaneously. Powerful math functions can be
used to analyze the differences between channels, making difficult measurements like
output stage compression and intermodulation distortion easy to identify and to correct.

THE MODEL 4400A IS THE
LEADER IN PULSE
MEASUREMENTS
The Model 4400A provides powerversus-time waveform analysis of repetitive
RF signals. Applications include AM, radar,
TDMA, and GSM, as well as RF amplifier
linearity testing. The time base extends to
10 nanoseconds per division with internal
and external triggering. The logarithmic
power display permits the entire dynamic
range of more than 60 dB to be seen at the
same time.
Convenient scale and centering controls
allow vertical expansion of any portion of
the display. A linear display scale is also
provided covering power levels from
nanowatts to megawatts. Two adjustable
markers can read the power at any point
across the waveform. In addition, the markers
can be used to define a region on the
waveform in which maximum power (peak
hold), minimum power, long-term average
power, and peak-to-average ration are
measured.
This function is especially useful for
characterizing the power level over a portion
of the top of a pulse, such as top-level power.
Two adjustable reference lines can be used
with the markers to identify and measure
particular power levels.
The reference lines also have the ability to
automatically track the following:
· Markers
· Top/Bottom Power
· Distal/Mesial Power
· Distal/Proximal Power
An Automeasure function measures and
calculates 14 common parameters of a pulse
waveform and makes them available at all
times in a both a summary text table and
individually as a user-defined display
parameter. The 14 Automeasure functions
are:
· Peak Power
· Pulse Power
· Average Power · Overshoot
· Risetime
· Falltime
· Top Amplitude
· Bottom

· Pulse Width
· Pulse Period
· Duty Cycle

SOPHISTICATED SIGNAL
PROCESSING FOR FAST,
AUTOMATIC MEASUREMENTS
Both the Models 4400A and 4500A
have a dedicated floating point digital
signal processor that performs shaping,
filtering, calibration, offset compensation,
and conversion of the test signal. Random
repetitive sampling and selectable
averaging provide accurate, stable
measurements of all user-programmed
waveform parameters. Digital signal
processing permits pre-trigger information.
Logarithmic detection provides the best
dynamic range of 60 dB (-40 to +20 dBm)
for peak power measurments.
Measurements are fast…two marker
values and their delta are available 80
times per second over the bus, and all 14
automatic measurements are available 20
times per second.

CUMULATIVE DISTRIBUTION
FUNCTION (CDF)
The Model 4500A CDF is a plot of
power on the vertical axis versus
probability on the horizontal axis. The
logarithmic power capability allows the
entire dynamic range to be viewed at one
time or a small region to be expanded up
to 0.1 dB/division for detailed analysis.
Likewise, the probability scale can be
expanded up to 0.1%/division. Both scales
can be offset over their full range to bring
any portion of the magnified CDF into
view. For every possible power level (p)
within the total dynamic range, the CDF
shows the probability in percent that the
measured power is less than or equal to p.
The maximum power level during the
entire run will appear at 100% probability.
The adjustable markers allow the power
to be read at any probability value along
the curve, interpolating to a resolution of
0.01%. Adjustable reference lines allow
the probability to be read for any power
level to a resolution of 0.01 dBm.
Summary results are continually updated
and appear at the top of the display, as
follows:
· Peak Power
COMPLEMENTARY
CUMULATIVE DISTRIBUTION
FUNCTION
The same histogram data can be used
to display the complement of the CDF or
CCDF, which is also called the 1-CDF
because of the manner in which it is
calculated. For every possible power level
(p) within the totally dynamic range, the
CCDF shows the probability in percent that
the measured power is greater than p.
This definition flips the CDF curve from left
to right placing the maximum power value
on the zero percentage axis. This form is
often more convenient to use, but contains
the same information as the CDF.
· Average Power
· Peak-to-Average Ratio
· Total Elapsed Time
· Total Number of Samples
CCDF of 8 carriers spaced 700 kHz
apart from 1.8 GHz to 1.8049 GHz
and phase aligned for highest peak

· Tolerance
· Reference Line Value
Alternatively, a TEXT display may be
selected to display the above in addition to
the following:
· Minimum Power
· Dynamic Range
· Confidence
· Marker Position and Value
· Reference Line Position and Value
When the second channel is installed,
the CDFs for the two channels can be
compared using the Math channel. CDFs
can also be saved into REF1 and REF2
and to the floppy disk. The confidence
level of the CDF is determined by the
number of samples taken. For many
purposes, useful results are obtained in
just a few seconds of run time. For events
with a low probability of occurrence, the
run time must be increased to ensure
capture.
PROBABILITY DENSITY
FUNCTION (PDF)
values described above does not have a
density function. However, it is useful for
qualitative analysis to create an
approximate PDF from the first-order
derivative of the CDF. The process of
differentiation exaggerates any errors in
the CDF values. For this reason,
measurements should always be made
from the CDF or CCDF. The PDF is useful
for visualizing QAM and other signals that
have a finite number of discrete levels. For
random noise signals, A Gaussian
amplitude distribution will appear as a
Rayleigh distribution in the linear power
domain.
PDF of 8 carriers spaced 700 kHz
apart from 1.8 GHz to 1.88049 GHz
and phase aligned for highest peak
power.
The TEXT display of measurements for
the PDF is the same as for the CDF and
CCDF. Adjustable markers and reference
lines are also provided; there are no
marker measurements in the PDF mode.
The cumulative distribution
function can be further
processed to obtain an
approximate probability density
function or PDF. The PDF
shows the relative occurrence
of the various power levels.
The probability that the power
lies between any two values on
the power axis is equal to the
integral of the PDF between
the two values. When the
difference between the two
values is equal to zero, the
integral of the PDF is also zero.
This means that it is not
possible to determine the
probability of occurrence of a
particular power level. Strictly
speaking, a discrete array such
as the histogram of power
