How to use two difference bitrate.

Hi, I want to simulate my system using two difference bitrate.

I need to set bitrate1 – 1.5Gbps, bitrate2 – 10Mbps.

Generally, two difference bitrate cannot be allowed in one layout.

How do I put 2 difference bitrate in one layer?

Is there any other solution?

      Hi Seungho, I tipically add a Global Parameter for the second BitRate. If the two bitrates are very different (like 100G and 10G), you have to keep an eye on the Sample Rate to avoid that one of the two has not enough rate for sampling or alasing may happen.

      Hope this helps,

      If I understand you can duplicate the layout, this layout you doubled will have the same components of the first and the only thing you change is going in global parameters and changing the bit rate

        In the same arquivo.osd you’ll have three equal projects with the only difference in bit rate

      I’m not sure about system you are trying to model but you may also consider 2 different modulators…

      But Heitor’s method is the easiest one!

      Using “duplicate layout” is the best option.
