Hi madd,

You can create something similar to a constellation plot by wiring your data into an XY Graph or Waveform Graph or Chart. Then right click on the graph or chart and select Properties. Go to the Plots tab and change the line type to None.

Hi Madd,

Modulation Toolkit has two different types of visualization: 1) IQ Graph which is simply the XY representation of the In Phase and Quadrature Phase samples. This can be acomplish as follows:

2) Constellation Plot has two plots in the same graph: the symbols (points) and the transitions. Therefore it knows the timing of the baseband data.

Hello

I am trying to make a program for 8 PSK Modulation but not able to make it. Can you please help me with the program for 8 PSK modulation.

Hi Harsh,

You are going to want to use the Modulation Toolkit. This is not strictly necessary, you can always develop the modulation on your own, but it makes it much easier. You may already have the Modulation Toolkit on your computer, it comes with the RF Device Drivers.

You may also have more luck posting in the RF Measurement Devices Forum.

Cheers,

And if you want to know what VI you should use for PSK, MT Modulate PSK and MT Demodulate PSK will help.
