4500B RF Peak Power Analyzer
The Boonton Model 4500B is the instrument of choice for
capturing, displaying, analyzing and characterizing RF power
in both the time and statistical domains. Applications include
pulsed RF such as RADAR, TDMA and GSM, pseudorandom or
noise-like signals such as CDMA and WLAN and modulated time
slotted signals such as GSM-EDGE and TD-SCDMA.
The 4500B features 100 psec timebase resolution, video bandwidth up to 65 MHz (sensor dependent), flexible triggering and
greater than 70 dB dynamic range (sensor dependent) without
any range switching to cover the most demanding peak power
measurement applications. The 4500B also features continuous statistical analysis of power (optional) at acquisition rates
up to 25 MSa/s, a text display of up to 15 automatic measurements per channel as well as envelope and persistence views to
provide fast in-depth signal analysis. Convenient I/O including
USB ports for storing data such as instrument setups, trace
waveforms and bitmap image files.

Superior Time Capture
The Boonton 4500B features a large 8.4” diagonal TFT
color LCD, 640 x 480 pixels, with CCFL backlight for a
clear view of up to two live RF channels, two live trigger
channels, two stored memory channels and one live
math channel simultaneously.
The need to clearly view multiple channels can be invaluable in many applications. The large color display in the
4500B is especially well suited for multiple channel
applications. User selectable colors are used to distinguish overlapping traces and to color correlate graphical
channel data with its measurements. For example, if the
color of the channel 1 is yellow, then the measurements
calculated on channel 1 are also yellow. The traces and
measurements are clearly marked and color correlated.

The 4500B gives the user the flexibility to customize the
Updating Simultaneously
display by allowing them to select the measurements or
specific parametric settings and measurement indicators they wish to display. These measurements can be
grouped to avoid clutter.
Unique Trigger System
The 4500B features a unique trigger qualifier that allows a user to qualify the trigger on a specific event or
a specific delay time allowing a user-selected pulse to
be captured, even when its timing is variable. Modern
communications signals typically have long frames of
data and it is often important to lock a peak power
acquisition to a specific time slot or to a specific event
within a group. The B trigger qualifier eliminates problematic synchronization issues associated with time
jitter within pulse bursts that are often found in UWB
and RADAR applications. This qualifier may be set up
to 999,999 events or up to 1 second.

Automatic Analysis
The 4500B provides power-versus-time waveform
analysis of repetitive RF signals. Applications include
TDMA and GSM, as well as RF amplifier linearity testing,
RADAR, satcom, and avionics. The timebase extends to
5 nsec/div and the logarithmic power display will show
more than 70 dB dynamic ranges at the same time.
Peak power sensors are available that feature <7 nsec
risetime (video bandwidth up to 65 MHz) and dynamic
range of 70 dB (pulse mode) or 80 dB (modulated
mode). These sensors have been optimized for use with
the 4500B and are ideal for measuring RADAR or signals
in 3G and future 4G wireless systems that use complex
modulation such as OFDM.
Two adjustable markers can read the power at any point
across the waveform. In addition, the markers can be
Figure 3: Pulsed RF including width, rise time & fall time measurements
used to define the portion of the waveform in which the
maximum power, minimum power, long term average
power and peak to average ratios are measured. This is
especially useful for characterizing the power level over
a portion of the top of a pulse. An auto measure function
measures and calculates 15 common power and timing
parameters. All parameters for up to four active channels
are summarized in a Text display and are also available as
user defined display parameters above the Graph display.
Powerful Statistical Analysis
The 4500B features optional probability density functions (PDF) and cumulative distribution functions (CDF,
CCDF) to accurately characterize noise-like RF such as
CDMA, HDTV and WLAN. These statistical functions build
and analyze a very large population of power samples
continuously at a rate of up to 25 MHz or triggered up
to 50 MHz on two channels simultaneously. These functions are fast, accurate and allow the measurement of
very infrequent power peaks for a user-defined population size or acquisition interval. Although the programmable acquisition time can be very long or continuous,
even short runs can resolve very low probabilities, due to
the extremely high sample throughput.
