<pre>IB3W0: L2 CAP ID error was intermittant.  Mostly ran with out problem.
IB4W3: Known problem.  Needs time to "warm-up,"  problem goes away after ~10 minutes of data taking.

<pre>The previous entry had bad linebreaks making it difficult to read, so I'm reposting it: 
 
b0fib07 checkout summary: 
 
I found the following problems when looking at wedges within this crate. 
 
----IB3W2---- 
All initializing readback in this wedge is zero.  According to the problem database, these readbacks should not be masked.  When reading this wedge out, all channels returned c2c2.  Gino suspects this is a grounding problem (he had a similar problem previously).  This will be investigated further. 
 
----IB4W0/1---- 
IB4W1L3 (both bias lines 0 and 1) does not look biased from the dnoise plots (see entry below). 
 
----IB5W0/1---- 
IB5W1L2 bias 1 may not be biased, but it's difficult to tell. See entry below. 
 
----IB5W4/5---- 
IB5W5L3 gave initialization readback 0.  This ladder does NOT have init readback masked.  Furthermore, this ladder only returned c2c2 during readout.  According to problem DB, there should be no problems with this ladder. 
 
The following ladders didn't look biased from plots (see entry below): 
IB5W4L2 bias 1 
IB5W5L4 bias 1 
 
In addition, the following ladders had zero bias currents, but it was impossible to tell if they were biased via dnoise measurement because the data coming out was not good: 
IB5W5L1 bias 0          (Had sequencing errors, which are already 
                         reported in problem DB) 
IB5W5L3 bias 0 and 1    (Only readout c2c2, as mentioned above) 
 
----LB1W0/1---- 
The following ladders had zero bias currents, and it could not be verified they are biased via dnoise measurements because this is L00: 
LB1W0L0 
LB1W0L1 
LB1W0L2 
LB1W0L3 
 
----LB1W4/5---- 
The following ladders had zero bias currents, and it could not be verified they are biased via dnoise measurements because this is L00: 
LB1W4L1 
LB1W4L2 
LB1W4L3

<pre>Executive summary of work needing to be done for b0fib07:

IB3W2: grounding problem
IB5W1L2: May not be biased.  Check dnoise again.
IB5W5L4: Not biasing
IB5W5L3: Does not initialize; does not read out.

Use another method to determine if other ladders with zero bias currents are biased.</pre>

Going through all ladders in the NW corner with new problems.  Here's the first: 
<br><br> 
IB2W2L3 will bias and successfully initializes and reads back the initialization bitstream, but will not take data.  It gives "00 Sequence errors" and the raw data looks like garbage (first chip ID and cap ID, then garbage, finally c2c2c4).  Consulted with David and Marcel, plan is to swap DOIM first and try to narrow down where the problem is.

<pre>Being I touched (and I have to put them back in shape) the cables for SB2W8 at the PS and this is SB2W7 it is possible that the bias cable has to be reseated at the PS. I would check it before going to the bore.</pre>

Our friend ISL TE-CCW2-1OUT is back and fired the interlock.  I masked him (by pulling out the black wire first - thanks Andy!). I caused an uber trip in the meantime.  All is well now, except SB2W8 is tripped since it was powered previously for testing.

This RTD has been out of the interlocks for a long time because of its flakey behavior.  I stuck it back in a couple days ago to see what it would do --- and here we are.  I think it's fair to pronounce it dead.

<h3> IB5W0 </h3> 
Gistos of noise/dnoise  show several counts  of common mode noise, maybe it is not biased. Need to be investigated.

<h3> IB5W5L3 </h3> 
We tried to run this ladder, no success so far. 
We can talk to the chips, (changing ISLE bits changes the currents ...) but no readback at all. If we try to run, we get the following :

<pre>These are the two bias currents for the last weeks for IB0W2L0. 
It does not draw any current now, on either of the two lines. 
When looking at noise/dnoise, the outer of the two ladders seems not depleted (a few counts of common mode noise.... (see next plot).</pre>

We don't see any current on Ibias0, Ibias1 is 445 muA.Outer ladder looks better than it used to while inner ladder is worse. This ladder has history of bias problems and possible pinhole. bias0 problem might be new, is there anything, we can do about it ?

this one has history in pdb, FE oscillation candidate, no physics on chips 4-11 reported. Now we only see high noise on chips 4-7.
Bias current 0,0 for bias0, bias1. 1-1.5 counts CM noise, not depleted ?

<pre>SB5W0L3 has trouble on phi-side since clock glitch but used to give data when rdriver=6 (instead of 4). z-side is chopped.
Did not give data yesterday. Looked at it again today and found rdriver=0 in svxdaq (?). When I set it to 6 (left plot) I get similar data to what Rong-Shyang posted before. But I even get good data with rdriver=4 (right plot)! So something improved :)</pre>

These are plots for the fiv layers in IB5W0. TO me most of the ladders don't look very biased, but I'm not much of an ISL expert, maybe this is normal? Bias currents were:
<pre>
HDI0: Ibias0=3, Ibias1=0, CM noise on inner ladder<br>
HDI1: Ibias0=0, Ibias1=6, both more or less ok<br>
HDI2: Ibias0=20, Ibias1=4, CM noise on inner (a lot), on outer (a little)<br>
HDI3: Ibias0=4, Ibias1=11, CM noise on outer, inner is good<br>
HDI4: Ibias0=39, Ibias1=15, CM noise on both
</pre>

SB2W8 is back with the HV ON and LV OFF (disconnected) so that we can measure leakage versus temperature profiles during the warm-up and cool-down that are happening during the next few days. 
I also reached an agreement with EVA so that if the cooling system trips she will recover that above described status of the wedge.

<pre>We did bias cable measurements on problem ladders in the southwest corner, top crate.  We found: 
 
IB0W2L0, bias 1: resistances inconsistent with healthy ladder.   
IB0W2L0, bias 0: resistances consistent with healthy ladder.   
 
IB1W4L0, bias 1: resistances consistent with healthy ladder.   
IB1W4L0, bias 0: resistances consistent with healthy ladder.   
On this cable, we noticed the bias 1 adapter was very loosely plugged into the power supply. 
 
IB2W1L0, bias 1: resistances inconsistent with healthy ladder.   
IB2W1L0, bias 0: resistances consistent with healthy ladder.   
 
We would like to note that bias 1, L0 is the conductor on the outside edge of the 90 pin junction card connector.</pre>

<pre>I climbed up to NW TOP TOP and probed the SB2W1L3 DVDD lines (these have been tripping.)  I observed either a short (or 1 Ohm) between the DVP and DVN lines for both pairs of conductors. 
 
I suggest boroscoping the junction card -- DVDD 3 is on the outer edge of the 90 pin connector. </pre>

<h3>IB5W0</h3> 
I biased all of these ladders and I see current on all those bias lines.

<!-- Date: Fri Oct 15 16:34:29 2004 -->
<pre>To summarize, we found three problems during today's cable probing: 
 
IB0W2L0 has an open on its bias1 lines. 
IB2W1L0 has an open on its bias1 lines. 
SB2W1L3 has a short between DVDD positive and ground (DVP and DVN.) 
 
The two bias line opens could be caused by a small gap on one side of the 90 pin connector.  The DVDD short is a little hard to explain using the junction card hypothesis, but the DVDD L3 conductors lie on the far edge of the connector. 
 
All of their junction cards lie in the west bore.

</p> 
Found that the Ground cable coming out from the JC of IB3W1 is terminated on a female connector that is hanging in the air.

Found a male connector hanging in the air that is connected to the COT face.

This connection must have been broken between the beginning of the shut down and the beginning of the testing.

It is not trivial to put the connection back so we are going to think about it over the w-e.

<b>We inspected the junction cards on three ladders:</b> 
<br><br> 
IB0W2: why? bias problem L0.  visual inspection: gap between the cards.  action: we pushed on the junction card, but the gap did not appear to close much if at all.  when you push on it, both halves of the card move together.   
<br><br> 
SB2W1: why? DVDD short in L3 causes trip.  visual inspection: looks fine.  action: none.  problem likely somewhere else.

IB2W1 why? bias problem L0.  visual inspection: looked unseated.  action: pushed on it and it looked like it may have helped.

I just tried to power SB2W1L3, it only tripped once on DVDD and then came up nicely ..... Need to reconfirm that tomorrow.
