[casper] setting up the equalizer gains for poco

[Mandana Amiri]

Hi all,

We have finally setup two dual-polarization antennas and we are 
acquiring data using a Roach board and 2 iADC boards. We are running a 
slight variation of poco design in tutorial 4, sampling at 850MHz. We 
adjusted the equalizer gains for each frequency bin separately, but the 
same for all 4 inputs (a, b, c, d). I realize now that one has to 
monitor the overall power and re-equalize these gains to avoid clipping. 
Our current plan is to find out experimentally how often we need to 
re-adjust these gains.

Is there any guideline or advice on how to set these gains?

I came across the corr_eq_init.py in the corr package, but I am missing 
the idea behind the equalization polynomials (or is this because of a 
particular setup?).

Thanks,
Mandana
