Hi all:
This issue has been resolved. There was a bug in my design in a downstream
block that creates packets.
Thanks a lot for you help,

How about this: Send me a copy of the model and I'll do a sanity check :-)

@Dave:
We have never seen such behavior in simulations. I am double checking
though.

Comments:
-The FFT is probably fine. If it was broken, it would probably be 100%
broken. At least this looks like a spectrum
-It appears to me as if the broken section is exactly 1/8th of the
spectrum. Did you hook up all of your outputs correctly?
-What's up with the spikes in the spectrum?
Hi, Nimish,
Does this occur in simulation as well?

hi nimish,
this could be a sync pulse problem???
how often do you inject a sync pulse?
did you check the re-order block in your fft to figure out the
minimum period sync pulse that's allowed for that particular FFT?
the casper memo on sync pulse generation has info on this.

Hi Glenn,
Yes, that is the plan, but we have some issues using snap blocks
independent of this. Hence, wanted to know if someone has seen such
behavior before as we continue to probe as you have suggested.
Thanks,
Nimish

Hi Nimish,
My suggestion is to add snapshot blocks triggered on the sync pulse
directly after the FFT and after the blocks that follow it. You can
then look at the signal at each stage and see at which stage that
strange behavior is occurring. You can also add a "test vector
generator" that puts in
Hi all:
I am attaching a plot for Power of two inputs vs frequency channels. As can
be seen, we have this persistent problem where some channels at the end
just do not make any sense. We suspect that there is something going wrong
in the FFT block. Has anybody seen such behavior before or can thin
