iqtools gui multiemitter generation

In "iqtools" matlab code, i chose for multiemitter generation, there i'm giving some frequency offset and delay for 1 channel AWG 64GSa/s option for generating those frequency and i successfully generated in spectrum analyzer which i was observed in that. Now my question is to 'generate mutiple signals at a  time with delay in 2  or more channels using AWG'. what should i change the code to get my solution for the question in single quotation.
for ex: i give each freq to each channel input freq's like 5GHz,8GHz,2GHz and having 'pri', 'pw' and there is some delay i want to give it to each freq and thats should be download in spectrum Analyzer. Is that possible to generate? and How? I want some matlab code for this generation.
