<div>Hi Rick,</div>
<div><br>
</div>
<div>EA09: It looks like the WO-23563 (please see the last stress test - Dec 19).</div>
<div>But it is IFA U to Q, except by X, which is IFB</div>
<div><br>
</div>
<div>EA12 is WO-23663 (see the array status email yesterday)</div>
<div>But it only affects IFC at X and higher (on C-band is IFC and IFD).</div>
<div><br>
</div>
<div>Could you please confirm your IF report? On the fringe screen, the IF identification of zeros of TCAL0004 looks compatible with what I described above</div>
<div><br>
</div>
<div>Cheers</div>
<div><br>
</div>
<div>Pedro</div>

Two antennas have 'zero PDif' troubles — PSum looks good, but 'PDif' are just zero-centered noise. </div>
