Hi, I am Ben Zarlingo from Agilent Technologies and I am here to show you real-time spectrum
analysis on the Agilent PXA Signal Analyzer. No matter how elusive the signals you are
looking for or how dynamic the signal environment, new real-time spectrum analysis options in
the PXA will give you the answers you need. Real-time spectrum analysis and frequency mask
triggering can be added to any PXA signal analyzer, either new or one you already own.
The real-time options cover bandwidths of 85 and 160 MHz to match the signals and signal
environments you need to measure. Combining real-time analysis, advanced displays,
frequency mask triggering and exceptional spectrum analyzer performance, the Agilent PXA is a flexible
and upgradable solution to even the toughest signal analysis challenges. Real-time analysis
lets you find, capture and understand elusive signals whether you know about them or not.
The core of real-time analysis is fast spectrum measurements, (almost 300,000 spectra per second)
along with advanced displays to show them and a frequency mask trigger to capture
the signal you want. Measurement speed only really counts when it is combined with fundamental
performance to match. The real-time PXA sets new standards in real-time bandwidth at 160 MHz,
dynamic range of 75 dBc, and frequency coverage to 50 GHz. A fundamental task for a real-time
analyzer is to make sure you do not miss any signal. In the PXA, signals as short as 3.6 µs
can be detected with 100% probability of intercept. All this performance is available
for both real-time spectrum measurements and frequency mask triggering. In the PXA, real-time
signal analysis is as close as a keystroke, simply selecting another measurement mode.
Use the traditional spectrum analyzer approach that you understand and trust. Controls are
simple and intuitive. Displays, such as density and spectrogram, show lots of information
on a single screen, and custom color settings allow you to focus on large or small signals
or on signal behavior that is most frequent or most rare. In density displays, every measurement
result is counted with no signals missed and color shows how often any signal occurred
in both amplitude and frequency. See signals inside of other signals. Where time relationships
are important, the spectrogram display adds a time axis, time slices as short as 100 µs,
and a scrollable buffer holding up to 10,000 traces. Real-time processing also supports
a flexible frequency mask trigger; the mask can be manually entered with precise details
or automatically generated from measured spectrum. Any mask can be easily and intuitively edited.
Masks can be upper or lower or both, and trigger logic criteria can be selected to capture
just the signal behavior you are looking for. Sometimes just finding a signal is enough,
but it is often just the start of engineering the solution, finding causes and optimizing
performance. The real-time frequency mask trigger supports all measurement and time-capture
modes of the industry-standard 89600 VSA software. Complete measurements in one box. Triggered
time capture is especially powerful for agile signals in complex signal environments. Adjustable
playback speed and advanced display types make the VSA a great complement to real-time
spectrum. Spectrograms from captured data reveal signal timing in detail, allowing any
signal to be isolated in time and frequency for analysis. The 89600 VSA software allows
center frequency and span to be adjusted after capture. Zoom in on any signal for greater
insight, including analog or digital demodulation. The combination of real-time and vector signal
analysis provides a complete view of any signal. Real-time options expand the capabilities
of the PXA, providing unequaled performance and flexibility to handle the toughest measurements.
You can upgrade your new or existing PXA to the industry’s highest performance real-time
analysis. To learn more, visit the link on your screen, and thanks for watching.
