Hello, my name is Cherisa, and I’m an engineer
at Agilent Technologies. I’m excited to introduce Agilent’s new X series millimeter-wave
EXA signal analyzer. Currently the EXA is offered in 3, 7, 13 and 26.5 GHz frequency
options. And now we are extending our frequency coverage to include 32 and 44 GHz. Plus, we
have added an external mixing option that enables you to measure frequencies up to 325
GHz and beyond. With increasing radio frequency demands to
the millimeter wave frequencies, this is a great product for aerospace defense and wireless
applications. In today’s demonstration, I will show the EXA’s great sensitivity
at 44 and 67 GHz. Plus, I will demonstrate our phase noise application, which is one
of over 20 applications available on the new millimeter-wave EXA. So let’s get started. For my first demonstration, I will show you
the EXA’s performance at 44 GHz. For this set up we have the PSG signal generator outputting
a 44 GHz signal to our EXA signal analyzer. The EXA comes with an autotune function. And
by pressing the autotune function the signal analyzer detects the strongest signal within
the span. This is a great tool for quickly identifying your signal of interest. I will now turn the RF off. And we will take
a look at the noise floor performance of the EXA at 44 GHz. I will adjust the reference
of our signal so that we can see it on the screen. And I will place a noise marker at
44 GHz. As you can see, our noise floor performance
is approximately -129 dBm per Hz. We can improve the sensitivity by setting our attenuation
to 0 dB. And this further improves the noise floor performance of the analyzer. The new
millimeter-wave EXA comes with a preamplifier Option P44, that enables you to improve the
sensitivity all the way up to 44 GHz. And now you can see that the noise floor performance
of the new millimeter-wave EXA at 44 GHz is better than -150 dBm per Hz. For my next demonstration I would like to
highlight the measurements and applications available on the EXA. The EXA comes with standard
built in PowerSuite measurements which are located under the measure key. You can see
we have measurements such as channel power, occupied bandwidth and adjacent channel power.
Agilent also offers over 20 advanced measurement applications that can be added to the EXA.
And these are located under the mode key. Some of these measurements include phase noise,
noise figure, analog demod and Agilent’s powerful 89600 VSA software. Let’s take a look at our phase noise application.
This is showing you the phase noise on the log plot frequency view. It’s a single sideband
relative to the carrier. A marker has been placed at the 10 kHz offset. Within this application
we also have a decade table that can be turned on. And then you can view the phase noise
performance relative to the carrier by decade. This is just one of over 20 measurement applications
that are available on the new millimeter-wave EXA. For my next demonstration I will show you
the new millimeter-wave EXA’s performance at 67 GHz using our external mixing option.
To the set up, we have added Agilent’s M1970V wave guide harmonic mixer with frequency coverage
from 50 to 75 GHz. The smart harmonic mixer is easy to set up, you simply plug the USB
into the USB port of the signal analyzer, and the hardware is automatically detected. The RF signal from the PSG is now coming into
the input of the mixer. And we have a single cable now for the LO and the IF. The EXA automatically
sets the display to show the frequency span of the mixer and it adjusts the power level
of the local oscillator. As you can see, because this is a mixer, we
have mixing products as well as images. And the EXA comes with a signal ID function which
is located underneath our input/output key. An external mixer, and when you turn signal
ID on, your signal of interest is easily found and you’re ready to make measurements. I’ve centered our signal at 67 GHz, and
now let’s take a look at the noise floor performance at this frequency. I will turn
the RF off, then I will place a noise marker at 67 GHz. And as you can see, we are showing
a noise floor reading of -145 dBm per Hz at 67 GHz. I have just shown you the new EXA’s excellent
performance at 44 GHz and also how we can extend our frequency coverage up to 325 GHz
and beyond by using our external mixers and our external mixing option. I’ve also shown
you our phase noise application, which is one of over 20 measurement applications available
on the new EXA. For further information, please see the URL shown and thanks for watching.
