Hi, my name is David Tu. I'm an application engineer for Agilent Technologies and soon
to be Keysight Technologies. In today's video we're going to talk about channel
coupling. So it can actually be really challenging for engineers like you to couple two channels
together and keep a phase amplitude or frequency relationship between the two channels. The
act of keeping them synchronized as you change the parameter is actually pretty difficult
and it can be actually very tedious. In today's video we're going to show you a dual channel
Trueform generator which makes keeping track of those two signals a lot simpler. Some challenge
areas where this can be used is maybe you have a divided frequency where you have two
taps in your circuits and you want to have the same signal but maybe different frequency
ratio or perhaps you have an opposite amplitude in your signals and you want to maybe create
a differential signal.
So let's go and go to our function generator and do that really easily with the front panel.
So right now I already have two sine wave outputs. I've got the generator, the 33600A
in dual display mode so you can see channel one and channel two together. So let's go
ahead and turn on dual channel which will turn on our coupling and let's turn on frequency
coupling. So let's go ahead and set channel two to be half the frequency of channel one.
Press done. You can see on the generator that the frequency of channel one is 1 kilo hertz
and the frequency of channel two is 500 Hertz.
Over here on the scope you can actually see that visually. So as I change the frequency
of channel one you can see that channel two is about half of what channel one is. So no
matter where I go. That's frequency coupling. If I go back to dual channel mode and look
at the amplitude coupling when we turn that on and now as I change the amplitude on channel one
channel two is going to change exactly the same. So it's going to keep that relationship
with barely any work on my part.
Trueform Waveform generators makes it a lot easier to simulate a pair of signals that
are related with either your phase amplitude or frequency. Save time and frustration with
Trueform. Thank you.
