Hello Sarath Chandaran,
I completely agree with both Fayiqa and Burhan….First of all check the link posted by fayiqa.. It will no doubt be very helpful to you.. And then what you need to do is that keep number of iterations more than one. Preferebably the number of iterations should be 3 or 4. Also do not forget to change the signal index at the right top corner of analyzer.Hope this will help you get the upstream output signal..
Regards
Sahil Singh
