4500B

The Boonton Model 4500B is the instrument

T

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 greater than 35 MHz
(sensor dependent), flexible triggering and
greater than 60 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 bit
map image files.

Capture Multiple Channels, Marker Measurements,

Automatic Measurements and Status in One Display

Figure 1:

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 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.

Capture a Signal Based on a User-Selected

Pulse or Time Delay

4500B RF PEAK POWER ANALYZER

Figure 2:

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.

Figure 3:

The 4500B features persistence and envelope displays to aid in the analysis of noise-like
signals with complex modulation schemes such as WLAN and CDMA. Persistence and
envelope displays provide a fast view of the maximum and minimum excursions of the
signal under test. These display modes provide a clear, large screen representation of
changing signals. The combination of a large 8.4” diagonal color display with persis­tence and envelope displays make viewing signals far easier than with traditional
bench-top power meters.

Analyze Your Signal with Automatic

Measurements and Markers

4500B RF PEAK POWER ANALYZER

Figure 4:

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 60 dB dynamic range.

Two adjustable markers can read the power at any point across the waveform. In
addition, the markers can be 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.

Analyze Your Signal with Channel Math

Figure 5:

Channel math can be performed on active and saved memory traces. These powerful
math functions can be used to analyze the differences between channels, making diffi­cult measurements like output stage compression and inter-modulation distortion easy
to identify and correct. The large color display provides a clear view of the active chan­nels and continuously updated math function. Status and measurement data is color
correlated with the associated channel or math function allowing for quick setup and
clear views of multiple channel measurements at the same time.

Analyze Your Signal With Time Gated

Measurements

4500B RF PEAK POWER ANALYZER

Figure 6:

Optional statistical power measurement techniques are powerful tools in measuring
noise-like signals such as CDMA, QAM, or OFDM. Complementary cumulative distribu­tion function (CCDF) shows the peak power, average power and the peak-to-average
ratio as well as the probability of occurrence of different power levels with respect to
time. The instantaneous power values are sorted by amplitude and counted, and the
values are displayed as a power level vs. percent probability of occurrence. A powerful
analysis technique in the 4500B allows user defined intervals of signals to be gated and
the statistical distribution calculated. Time gated measurements provide analysis of
specific areas of interest on a signal.

Characterize Your Signal With Fast

Statistical Analysis

Figure 7:

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.
