Hi, my name is Daren McClearnon, I'm a 5G solution marketing engineer for Keysight Technologies.
Our customers have been telling us three main challenges that prevent them from moving forward
in millimeter-wave measurements, and in this short video, we'll take a look at some approaches
to address those challenges.
First, let's take a look at our equipment setup.
On the signal generation side, we have a wideband arbitrary wave form generator whose bandwidth
is wide enough to not only make a 5 GHz-wide signal, but put it at a 5 GHz IF and make
the whole thing from base band so that a 5 GHz IF comes into a harmonic mixer head.
The harmonic mixer head has a local oscillator at 14.75 GHz from the signal generator, and
times six gives you 88 and a half GHz, minus the 5 GHz of the IF, makes an 83 and a half
GHz signal that goes into a 110 GHz signal analyzer, and when it comes time to demodulate
that signal, we will do that by taking the IF out the back of the analyzer into an 8
GHz-wide S series scope.
The first challenge that customers tell us about is sensitivity.
They are trying to meet spectral emissions compliance masks.
They're also trying to find spurs and problems at a very low level.
With this system, you're able to get down to minus 150 DBM per Hz across the entire
three to 110 GHz band, and that gives you the ability to demonstrate compliance not
only for the71 to 76 and 81 to 86 GHz bands that are specified today, but also to the
coming regulations up to 110 GHz that will be published shortly.
The second challenge is the ability to sweep across the entire range without spurs and
with full sensitivity, which is hard to do with today's banded solutions.
You're able to look at different artifacts with confidence and high sensitivity, and
also have the flexibility, as different spectrum allocations evolve around the world, to take
and adapt your measurements to wherever you need to go in one box.
The new UXA signal analyzer is able to go from three Hz to 110 GHz, allowing you full
flexibility.
Let's look at our spectrum at 83 GHz.
Here we have the main signal bandwidth, but we also see the LO feedthrough terms of the
times five and the times six LO terms.
You can also continue looking for spurious emissions and oscillations and susceptibility
throughout the band, which banded solutions might not let you do.
Another challenge that customers bring us is the extreme bandwidths of today's 5G signals.
The UXA signal analyzer is able to do one GHz of demodulation within the box, and if
you need more than one GHz, you can take to an IF and digitize on an S series oscilloscope
and get over 5 GHz of spur-free bandwidth.
This allows you to demodulate high order, fine quality signals at an EVM that was never
even possible at these bandwidths.
What you're looking at is a wide-bandwidth signal with EVM that is unprecedented for
an 83 GHz type band.
In this short video, you've seen how the UXA 110 GHz signal analyzer has the spur-free
sensitivity with wide-bandwidth demodulation across the entire band to allow you to overcome
challenges throughout millimeter-wave.
