In the previous topic, we have discussed the difference, of course, for the South to different you
know, in this topic, we are going to discuss the idea of this group, which is often used to control
the software defined radio, the IAU or software is a course, is a cross platform.
Graphical user interface application is demonstrated the interface of different transceiver boards,
and it is provided by the analog device.
So using this often you can different boards which are provided by the analog device.
So there are some board, for example, like this proposed here and different issues and their evaluation
board like it did in three six one ninety seven one, which we have discussed in the previous modules.
So using this software, these boards can be controlled.
Moreover, it support data transmission and capture of the data so that the data can be plotted in the
improvement in the frequency domain and in the constellation as well as cross correlation.
So what does it mean?
It means that we can have a time domain of a signal.
We have a frequency domain signal.
Moreover, we can plot the constellation points of signal and we can also find a cross correlation between
the input and output signal.
So this application source, several settings of a software defined will use to modify and we using
the graphical user interface so it can transmit only design signal.
Suppose you have designed a signal, for example, we have designed and five megahertz signal in a software,
for example, in Abidin or in the Matlab so that we have a match fail or we have a text file.
So using that file, this software transmitter signal and moreover, after a transmission, it also
captures that signal.
So this is the graphical user interface of this device.
So it is using a family of devices, for example, denied using X, so X can be one.
It can be three.
It can be four.
So as we have established in the previous module, so there are different uses available from these
families.
This can be used.
No, you can see in this user interface.
So we have a different kind of modes like this FTT or do more we can use and it can perform one or two
calibration and transmit are transmitting.
The C word can be controlled here.
Moreover, we can apply for that also in the piece by itself and we can choose the RF bandwidth, how
much maximum bandwidth signal can be transmitted and we can define the sampling rate of the signal here.
That is also efforts and we can choose the transmit frequency.
Suppose if we want to transmit at two point four gigahertz so we can choose the transmit frequency and
it can also do self calculation and tracking of quadrature at a dizzying pace when the C component,
if I want to use the external oscillator and I want him the nature of the board, then I have to take
this option and I can use the luchadores later externally and hardworking of the receiver can be controlled
here.
It can be using automatic mode or it can be controlled using the manual mode.
So similarly in the transmission system setting sort of level.
So these two local oscillator independent, we can set it a different frequency and this one is a different
frequency.
Moreover, we can control the gain of this transmission system and we can increase that relation or
we can decrease the duration as part of our need.
And this is the part of the digits mode where we can transmit the signal.
So by selecting this signal here, by loading the signal here so I can I can I can use the NQ component,
suppose I have designed and the 10 megahertz signal or a single signal, I can load that signal into
this software.
What it will do, it will transmit the identical component.
So all the zeros are.
This one is you and I have to select this one, so these are not disturbed convertor channels and my
basement will be converted to the analog and for that it will be transmitted.
This is a typical user interface graphical view.
So what we can see when we enable this channel of that in the application we have, we have a lot of
different components.
Suppose if I want to use to visualize that, I am going to hear so that I am the one where there will
be something look like to me based on a different signal, whether it is a radio or any kind of signal
and support is a sign.
So there was anything then it will be seen like this.
And if I want to use the frequency domain content I can visualize in the frequency domain, how can
we see suppose if the signal so I can see this to something like this and if you just sign your signal,
so I will see a spectrum like this.
So at this particular frequency I will see the beacon.
So using using this interface I can switch between the time domain plot and the frequency domain plot
and I can set that number of samples which I want to visualize here.
And moreover, we can also see the correlation point of a signal.
For example, this is for the pay scale for KWEM and here we can save the data here.
So using this option, we can save the data or we can capture that transmit data.
So once we have that transmitted and receive data so we can compare in the software, in the PC or in
the in the process of this device, wherever we can see the data, we can do for that analysis and provide
insightful information from the captured data.
This, of course, helps to control the hardware board and it can do a different parameter or change
the different parameters of the device using the software we can see here.
This is the frequency domain setting and I can use that for this size here.
And I can across the spectrum, suppose if I have recip so it will become more smoother.
Either way, it will be something like this, you can see.
So these are the settings which are very useful to Israel, this plot.
So in this topic, what we have discussed, we have discussed in a year or less what software or it
will do.
It will control and Asgeir hardware so that we can do a different parameter of Asgeir hardware and we
can transmit and receive signal as per our need.
Now, in the next week, they are going to learn that Jianyu to do.
