<h2> Lightlevels on f432</h2> 
We went down to measure the light level on f432. As comparison we took f430, a good ladder. 
This are the light levels measured using DC lightmeter 
<pre> 
f430		f432 
chan  2 75	chan 2  60 
chan  3 100	chan 3  45 
chan  4 55	chan 4  50 
chan  5 80	chan 5  35 
chan  6 90	chan 6  56 
chan  7 70	chan 7  44 
chan  8 50	chan 8  70 
chan  9 80	chan 9  65 
chan 10 60	chan 10 27 
</pre> 
For f432 chan 10 (OBDV) is flat at 27, all other oscillate, as expected. See also the two scope traces below for channel 8 (Bit 1) (channel 3 on scope) and Channel 10 (OBDV) (channel 1 on scope) 
So it seems, we have no clock. BE Cludge ?<br> 
This also explains, that Init readback is successful, but we don't see data.

<pre>BTW, the unit is nW. Also if there is no fiber connect on meter, it shows 0.1nW.</pre>
<!-- Comment: Mon Nov 22 10;33;40 comment by...rong -->
<pre>For search purpose, f432 is IB4W3L2.</pre>

Left is f430, right is f432

<pre>The other slightly weired thing is that f432 bit1 didn't show too much activity like f430.</pre>

AVDD and DVDD for f432

Got paged due to 'PS alarm' in IFix after Rack power restored.<a href=

shift elog</a>. 
Most of the FIB crates were rebooted but failed to connect to RTserver. Wedges belong to CAEN#8(b0fib03) lost communication (gray in PSGui). After restarting the RTserver, have all the fib crate rebooted and hockerization on CAEN#8 (with Jen and Ilsung).

<br>Rong asked me to take a look at the DAQ system... ran DAQ on ISL and SVX for a while. Everything is fine.

<pre>Bias current history for IB0W2L1, IB1W4L0, IB2W1L0, IB5W1L1 and IB5W4L2 which are all listed in the 'FE amp. oscillation' group.
Since f210 has found of lost bias line due to 6 house quench, I tried to look at the bias current history for other guys. They all show somehow weired behavior in one of the bias lines. Maybe that's also a reason we see oscillation running svxdaq and not seeing physics since we are not be able to deplete the sensors? should double check with the bias scan data.</pre>

<h3> f432 continued</h3> 
This morning we went in and removed the FTM from f432. We brought it over to Ken and installed the backend clock kludge. Ken has aligned it and it worked nicely in the test stand. We'' install iy as sson as the south wall has been moved.

For the records, f432 hat problems before with stuck cell ids and termination problems. So it might well be, that OBDV has been flaky before ....

AVDD,DVDD and Bias0/Bias1 for the last year. Clearly, something changed with DVDD, that used to be pretty stable before. 
The bias behavious is kind of interesting, what did happen on DS day 1100 ?

As a comparison: f432 (red), f430 (green) with AVDD, DVDD and Bias0-/Bias1. Although both show an intresting behaviour in the bias leakage current, the problems we see with f432 seem to be unique to this ladder, see e.g. DVDD.

<h3> Add to the fun ... </h3> 
If you don't have enough problems, create new ones. The DAQ people decide to move the vworks boot loader form b0dap24 to 83. Of course without telling us. That means, we couldn't reboot any crate any more. Steve and I yelled at them and they fixed this by reporgramming all our VME crate CPUS to boot from b0dap83. 
They all boot happily and things hould be fine. Took the system through a cold start, everything config'ed. Things look ok.

<h3> Software update </h3> 
The RunControl interface has been updated in the default version of svxii. (For the time being, the crates have booted from my version (identical) to test it. 
Prominent features are: 
<ul 
<li>Fib code ignores onlineflag again </li> 
<li>Ghostbuster is configured via RunControl </li> 
<li>SVX RSM register is now correctly set via RunControl  </li> 
</ul> 
In case there are any problems related to this, please tell me

<pre>Reboot svxinter then restart PSGui and IMon to respond the boot server change. They are all fine after rebooting.</pre>

<h3> Modified VTM</h3> 
We have put a modifed VTM in b0svx03 Slot 12, which correspond to  
SB3W4/W5. This VTM carries the Glink_Data Valid to Limo connector, so we can actually tell, when data arrive at the VRB. (We cannot do that using e.g. READBUSY.). This feature is mainly used by SCN and Marcel and has proven useful in the teststand. 
We took the system through a coldstart afterwards and we did not find any problems.
