Dear Sir,

 

I am using FMComms5 Plugin to transmit and receive data.

I have some questions below:

 

1. I have checked the basic iq data file . 

https://wiki.analog.com/resources/eval/user-guides/ad-fmcomms2-ebz/software/basic_iq_datafiles

I would like to generate 4 independent signals files.(8 iq signals)

But it still can not work.

 

FMComms5  Hardware setting:

TX1A_A connect with RX1A_A via cable.

TX2A_A connect with RX2A_A via cable.

TX1A_B connect with RX1A_B via cable.

TX2A_B connect with RX2A_B via cable.

 

Matlab file(Create TX datas):

 

t = 0:(1/30e6):1024/30e6 - 1/30e6; % Create time vector

FMComms5 Tx1 = round(exp(t*j*2*pi*1e6)'.*2047);
Tx2 = round(exp(t*j*2*pi*10e6)'.*2047);
Tx3 = round(exp(t*j*2*pi*5e6)'.*2047);
Tx4 = round(exp(t*j*2*pi*2e6)'.*2047);


datas =[ real(Tx1) imag(Tx1) real(Tx2) imag(Tx2) real(Tx3) imag(Tx3) real(Tx4) imag(Tx4)];

dlmwrite('TX_DATA.txt',datas,' ');

 

 

Results : It seems transmit two signals. TX1= TX3 (1.png) and TX2 =TX4 (2.png) 

 

 

 

2. Is it possible to continuous steaming data with Simulink model? (buffers are back to back without delay)l?
