PN9500 Digital Spectrum Monitoring

• Real Time FFT

• Built-in

• Wide and Narrow Span

• Harmonics measurement

• Pulsed Spectrum analysis

The Digital Spectrum Monitoring function finally
offers the PN9500 much more than traditional
phase noise measurements. In fact the PN9500
already integrated a frequency counter, a digital
oscilloscope, a power meter and now integrates
one of the best RF tools, a Digital Spectrum
Monitoring function.

The PN9500 has the inherent flexibility of having
plug-in options available in one integrated package
instead of having to rack and stack equipment and
deal with results correlation issues. The addition
of the DSM function simplifies connection
changes for the user by keeping the same instru­ment for multiple test tasks.

The DSM uses the microwave Local Oscillator
available in the PN9500 to down convert the RF
signal to an IF that is digitized by a 100 MS/s con­verter. Then a spectral analysis of the signal in a
real time bandwidth of 30 MHz is performed using
FFT processing.

Not only can the user perform narrowband spec­trum analysis but they can also select to measure
wideband spectrum into the DC to 18 GHz range.
The monitoring function can be specified into a
very flexible range.

As for a traditional spectrum analyzer, this func­tion measures power level, power variations,

ACPR, Harmonic distortion and more by setting markers. The DSM
software also allows exporting of text files or pictures in various for­mats for post-processing or storage in third party software.

In addition to the standard functions usually present on spectrum
analyzers, the DSM also integrates specific processes well adapted to
the RADAR market. In the case of a pulsed signal, it measures the
spectral response of a pulsed signal and analyzes the power differ­ence between the side lobes. This analysis is done with a 30 MHz
maximal span.

This new option also guarantees a better Return On Investment for
the owner as the Spectrum Monitoring function uses hardware parts
usually dedicated to phase noise measurements.

DSM is a software option available for all PN9500 systems as an
upgrade or an option in a new unit.
