Hi everyone, I'm going to demonstrate the conventional way of
performing zeroing and calibration using the traditional method versus the USB internal zeroing and cal.
So this is the typical power meter and power sensor setup.
Right now, I'm going to hook up the power meter and sensor.
Let's start the clock.
So one side, I'm going to hook up to Channel A,
and here I'm going to hook up the sensor to the 50 MHz reference port.
Now I'm going to select zero plus cal, for Channel A.
So now, let us wait.
Hmm, I think this is going to take us a while.
Imagine if you have to do this at the beginning of each shift.
So right now, we're going to exceed the one minute mark.
We've just completed the zeroing, and now we're doing the calibration on the sensor itself.
Okay. Here we go. Finally it's done.
So our clock here shows that it's the one minute mark
to perform the conventional way of doing the zeroing and cal for the conventional sensor.
Now let us take a look at the Keysight patented internal zero and calibration feature.
Here we have the same setup, except that we are now using the USB power sensor.
Let's start the clock.
All you need to do is just plug in the USB port.
And this, you don't need to connect to the 50 MHz reference port.
So that is the good thing that you eliminate one step of doing the internal zero and cal over here.
So now, I think it's about to complete the internal zero and cal, so let us wait.
There you go.
So as you all can see over here, it takes half of the time
compared to the conventional way of doing the internal zero and cal for the power meter and power sensor.
So this is how powerful the Keysight patented internal zero and cal is.
Now let us take a closer look at the Keysight patented internal zero and cal in our USB power sensor.
I think not most of you know that the moment you hook up the USB power sensor to the USB port
For example, like this, I'm hooking it up to the laptop.
You can actually see that there is a blinking LED at the rear of the USB power sensor.
Now it's green, and the moment it's finished it will stop blinking,
and now it has already performed the internal zero and cal on the sensor itself, so now you're ready to perform any measurements.
However, for the customer, if you think you still need to perform another round of internal zero and cal,
you can do that with our Keysight BenchVue software.
So now let us take a look at how to perform the internal zero and cal using our Keysight BenchVue software.
Okay, here we have a USB power sensor connected to our PC, which is running the Keysight BenchVue software,
and the sensor is connected to a signal generator for the signal source itself.
So now, let us run the cal and zero on the USB power sensor, and let's see how fast it takes.
Let's start our clock.
This will normally take us a couple of seconds to complete the internal zero and cal.
The moment it is completed, there will be a pop-out message that tells you that it has already completed the internal zero and cal in this case.
So there you go. As you can see, the message has popped up
and it only took us about 17 seconds to complete the internal zero and cal using our BenchVue software.
As you can see, this is really faster compared to the conventional method
of performing internal zero and cal using the meter and sensor itself.
Oops, we didn't switch off the power source.
So no worries, the sensor itself will block any signal coming into the sensor while performing internal zero and calibration,
so you do not need to worry about blowing your sensor bulkhead.
With this new feature from Keysight, actually you can reduce your setup time, especially during early of the shift,
and also reduce wear and tear for the connectors itself, when you plug in and unplug from the meter itself.

Thank you.
