Hi, I'm David Tu, and I'm from Keysight Technologies. In this video I'm going to show you how easy
it is to configure a USB power sensor, and use BenchVue software to do so. BenchVue provides
an advanced power analysis to be performed in real time, and gives you the ability to
capture, analyze, and export your measurement data and screenshots. So I have here a USB
power sensor. So let's go ahead and make some connections to our devices.
So first I'm going to make a connection to the USB port on my laptop here, and then I'm
going to make a connection to my signal generator, which already has a signal being generated
on the output. So once I've made those connections I'm going to go ahead, and go to BenchVue
and show you how easy it is to configure. Okay now I'm on my PC and I have BenchVue
version 2.6 here. You can easily find the power meter right here on the bottom side.
So I'm just going to double click that, and it's going to open up the application.
BenchVue works seamlessly with I/O Libraries to find instruments that are connected to
your PC. So just like that I'm able to start talking with my power meter. So I'm going
to stop the measurement that it starts off with, and do some simple configurations. So
normally you would do a cal plus zero every time you do a precise power meter measurement.
I've already done that, but within BenchVue you can see the button here. All you have
to do is just press that, and the power sensor will go ahead and do its own calibration.
With my RF signal generator, I have currently a 1-Gigahertz signal. So let's go ahead and
type that in, 1 Gigahertz, and leave the aperture setting as it is, and just start making that measurement now.
So on the RF signal generator I've got approximately a 10 dBm signal, and if we're measuring minus
9.8, which is accurate. So that's really all you need for making a numerical measurement,
but within BenchVue itself you have the ability to visualize your data in a couple of different ways
You can add an analog meter view, which will allow you to visualize the data, see
if it's moving around on you at all. You can also add in a data log view as well. So the
data log view basically allows you to visualize your average measurements over time, which
is very important.
Also in the data log view, you can also add some markers. So here I've got marker one,
and that's right here, and you can see the measurements at marker one, which is -9.8 dBm.
So you can move that around, and it'll move that around with two digits of
resolution it looks like. If you wanted to, you can also add in these different power
sensors. So I'm just going to connect that onto my PC now. So here we've already seen
the power meter automatically pop up. Again, we didn't have to do anything else. BenchVue
automatically found it. So just double click on that power sensor, and you have two different
views of your power sensor now.
So you can see your power sensor readings side by side. If you wanted to, you could
also export these readings to a different file format. So if you don't like your analysis
in BenchVue you could also export to MATLAB, or Excel, so I'm just going to go ahead and
export to Excel real quick, and press okay. All that data that was in this data log view
is now over here in Excel, which is pretty nice. A couple of other simple features that
BenchVue provides is a library of information for your particular instruments. So I have
here clicked on this power sensor, and it automatically pops up the available information
from BenchVue from different resources that BenchVue has tied into. BenchVue also supports
not only just a basic power meter, but also data acquisition units, DMMs, Function Generators,
network analyzers, oscilloscopes, power supplies, and spectrum analyzers.
As you can see, using a power sensor and a PC, you can easily use Keysight's BenchVue
program to get advanced power analysis done. So for more information, please go to Keysight.com
