[Keysight Opening playing]
Hello. My name is Chang.
I'm a product marketer with Keysight Technologies.
Today,
I would like to demonstrate new waveform creation software
that operates with several Keysight function
and pulse waveform generators.
I'm going to create complex custom waveform
for your own application.
This is what Keysight PathWave Waveform Builder Pro
looks like when you start it up.
You can choose to create a waveform,
create a sequence of waveforms,
open an existing waveform that you have created,
or import a waveform from other software in the CSV file format.
We are using Keysight 33500 Series
function or arbitrary waveform generator.
Now, we can set up waveform properties.
I will just leave this default at 100 milliseconds
with a sample rate of 1 megasample per second.
That gives us 100 kilo samples of data points to work with.
So, I hit ok
and I can get a scope-like display
where I can begin creating the waveform.
Let’s create a little more complex waveform
that might be similar to an application of yours.
I will select this trapezoidal waveform creation tool.
Suppose,
you have a device
and you are trying to simulate a power-up state and a dwell state.
Let's start with this trapezoid.
The first thing I can do with a trapezoid is to say how many cycles.
So, let’s say two cycles.
Let’s run it for the entire 100-millisecond display that we have.
I can set the delay time before I start to power up.
Let’s set that at 10 milliseconds.
I can change the hold time
that we are at full power on the trapezoidal shape.
We will set that to 30%, which is 15 milliseconds.
I can also change the rise and fall times.
Let’s have the fall time
be shorter than the rise time, say, 2 and ½ milliseconds.
So now I have the trapezoid
at the shape that models your power-on
and dwell condition and power off.
Again, I click ok.
And I have the trapezoid on the screen.
Before we send this to the instrument and look at it on the oscilloscope,
let’s model a glitch in the dwell state.
The way we are going to do that is to highlight a few points.
We’re going to subtract a DC value
from the dwell voltage
and let’s have it drop 1 volt from where the dwell is here.
Now in the preview window,
it’s just DC
so,
it’s not going to be clear
what it will look like at this point.
But we select ok.
This is a new window.
It’s a waveform math window
so this is the selected waveform.
This is the operation, which is DC.
I select ok to that.
Now, you can see that I have a glitch of 1 volt drop.
That is the dwell time on my voltage.
So now I have a waveform that’s ready to send to the instrument.
I will go to the communication menu again.
In this case, I will just send the data to the instrument
I will select Send to Instrument.
and you can see that
we have the 1 volt glitch dropout
in every waveform on every one cycle.
We just finished creating multi-cycle trapezoid signals.
Hopefully, this is familiar to some of you.
Again, thank you for watching.
