Hi, I’m Ken Christensen and I’m a Product Manager in the Power and Energy Division at
KeySight. And I’m Blake Vermeer, I’m an R&D Firmware Engineer here at KeySight as
well. In the next few minutes, Blake and I are going to give you an overview of the IntegraVision
Power Analyzer. The IntegraVision Power Analyzer is a purpose-built power analysis instrument
that has 0.05 percent accuracy and 16-bit resolution. With this instrument, you will be able to
see, measure, and prove the performance of your designs. First thing we’re going to
do is give you a tour of the connections on the back of the instrument. As we look at
the rear of the instrument, the first thing you’ll notice are the two power channels.
Unlike an oscilloscope, a power analyzer power channel has both voltage and current connections.
For the voltage connections, we use a banana plug connectors. These connectors are up to
1000 volts RMS. The current connections come in two varieties: either our direct connection
or a BNC connection for external probes. The direct connection has both a 2-amp and a 50-amp
connection and then those go through a shunt that’s built into the system. If you have
currents that are higher than the 50-amps, you’ll move the slide down and you’ll
expose the BNC connector for the external probes. And then as we circle around, we have
both trigger in, trigger out, and a 10-megahertz clock signal. All of these are with an SMA
connector. We deliberately made these different than the BNC connector so that you can’t
mistakenly connect a BNC to one of these other signals. Then finally we have a LAN connection
and a USB connection. With the LAN connection, you can actually use our remote front panel
software to control the instrument from a distance. If you have some type of concerns
around safety, either the current or the voltages, you can physically be further away from the
instrument and still have full control. Now, let’s move around to the front. When we
look at the front of the IntegraVision Power Analyzer, the first thing you’ll notice
is the large 12.1-inch touchscreen display. We have voltage, current, and power all displayed
on a single screen. You can see Channel 1 is in yellow and Channel 2 is in green. On
the right side of the instrument, you’ll see a number of knobs that look like any oscilloscope.
In fact, if you can use an oscilloscope, you can use the IntegraVision Power Analyzer.
And now, Blake is going to show us the setup of the power channels. So now I’m going
to give an overview of the channel menus. If we go into Channel 1 here, we can change
the coupling to be either AC or DC coupling, enable or disable anti-aliasing, and we can
have control of the current inputs. If we have a current probe hooked up, we can set
the ration and the offset for our probe. The last major control we have on the channel
menu is ranging. We have either automatic or fixed ranging. Fixed ranging is best when
you’re trying to capture small, transient events that may not be picked up by automatic
ranging. So Blake, now can you show us the triggering? Yes, so the triggering menu – we
can select what source we want to trigger from. It can be any of the voltage, current,
or power signals, external trigger or line trigger. And for the edge it can be either
rising, falling, or either. We can also change the trigger mode to be either auto trigger
or wait for trigger. In addition to this, we have our normal single trigger mode that you
can switch to as well. So now we’re going to talk about the continuous whole cycle analysis
mode of the IntegraVision Power Analyzer. So if I go into the CWA mode, we have four
different major categories of stuff we can measure. We can get basic power quality measurements
on our waveforms. We can measure harmonics of our waveforms. We can measure energy over
time of our waveforms and we can also measure the real-time efficiency. Our first major
menu is the power quality menu. We can measure AC voltage, AC current, DC voltage, DC current,
instantaneous power, power factor, crest factor. And we can also change the mode to be DC only
mode and we can see the ripple on our DC power supply if we were using one, to know how good
of a power supply it is. Our next major mode is harmonics. In harmonics mode, we can measure
the THD of our signal in real-time, plus at 60-hertz frequency we can see the individual
powers of up to the first 250 harmonics. After our harmonics menu, the next thin we can do
is energy measurements. In this case, we can set up how long we want to do our energy measurement
for – let’s say I want to do it for ten seconds – and I can start the measurement
and after ten seconds I will see how much power I consumed in that time. This can be
configured up to as much time as you’re going to possibly need for energy measurement.
So our last major mode is efficiency. In this mode, we can measure instantaneous input power
and output power and the real-time efficiency of our system. If our pre-built CWA modes
don’t meet your needs, you can build your own. If you go under the measurement menu,
you can add your own CWA measurements for any of the channels and display the information
that’s most important for you. Another unique feature about the IntegraVision Power Analyzer
is its ability to measure transient events. We have a DC-switching power supply hooked
up to our IntegraVision Power Analyzer and now we’re going to try to capture its inrush
current. So I’ve already set this display to just displaying current and I’m going
to go into the Channel 1 menu and set the ranging to fixed. This is important so we
can capture the full peak of the inrush current. So I set the inrush to 50 amps and the voltage
range to 200 volts. The next thing is I want to change the trigger to be triggering on
Current 1 and I’m just going to change the slope to any and set the trigger level to
a trigger level that will appropriately trigger for this application. Everything is two as
I adjusted the horizontal scale to be a little bit larger so I can easily capture the inrush
current plus the steady state. So now I’m going to start single shot mode and see if
we can capture it. Here we go. Now we can see we had a huge inrush current and then
gradually went down to steady state. If I go down into the measured menu, I can see
what the peak of the inrush current was and I can use the cursors to measure the time
of the inrush current event. As you can see, the scope-like features of this power analyzer
make it very easy to measure inrush current. You’ve seen this brief overview of the IntegraVision
Power Analyzer. With its easy connections and intuitive interface, you can quickly get
into the insight into of your designs. With this single instrument and its dynamic views,
you can see, measure, and prove the performance of your design. Thanks for watching.
