Test FADC V2

SBS DAQ VME computer (Linux, Intel CPU) "sbsvme22" and PC "sbs1" located in TestLab have been used for testing a new FADC V2.
PC computer is used to run CODA.
Original software and library from CODA group are located in /site/coda/contrib/devel/halla_moller/
We have copy of this directory to sbsvme22 computer in "~/git/" directory.

Testing FADC with CODA

Login to VME CPU (password from Alex or Bob):

> ssh root@sbsvme22

go to moller fadc directory:

> cd git/halla_moller/

Start CODA ROC manually

> coda_roc_rc3.5 -name TS1 -type ROC

Original CODA readout list is: ~/git/halla_moller/fadc/moller_rol/moller_list.c

CODA readout list with FADC parameters from configuration file is: ~/git/halla_moller/fadc/moller_rol/test_moller_list.c

To compile readout list:

> cd ~/git/halla_moller/fadc/moller_rol/
> make test_moller_list.so

Change readout list in database:

> dbedit

select "sbsfb" database,

select "MollerFADC" table,

change readout list in "TS1-code" cell,

exit from dbedit.

Login to sbs1 computer (password from Alex or Bob):

> ssh adaq@sbs1

Type in terminal:

> startcoda

Select session sbsfb1 and configuration MollerFADC

CODA file stored to directory: ~adaq/data/moller_NN.dat

Configuration file with FADC parameters is located in:

 sbsvme22:~/git/halla_moller/fadc/moller_rol/config_1.fadc

Testing FADC with standalone programs

Login to VME CPU:

> ssh root@sbsvme22

go to moller fadc test directory:

> cd git/halla_moller/fadc/mytest

FADC can be tested with external signals on inputs ("mode"=0), and with interrnal user defined waveform (PlayBack mode "mode">0).

In PlayBack mode waveforms is defined in configuration file, see file:

~/git/halla_moller/fadc/mytest/config_1.fadc

start readout program:

> ./famFadcTest <config_file_name> <mode> <adc_printout>
   config_file_name  - name of file with FADC parametes
   mode              - FADC run mode, mode=0 external signals; mode>0 - playback (number triggers=mode) (overrides 'mode' from config file)
   adc_printout      >0 print out adc data block; =0 - no printout adc data block

Examples:

load FADC parrameters from file "config_1.fadc", external inputs, print adc data block:

>  ./famFadcTest config_1.fadc 0 1

redirection of printout to file for analysis:

>  ./famFadcTest config_1.fadc 0 1 > fadc.dat

Simple analysis

Extracts ADC data from printout file

> adc_print.sh fadc.dat > adc0.dat

Setup root:

> setenv ROOTSYS /apps/root/PRO
> setenv PATH /apps/root/PRO/bin:${PATH}

or

> source setup_root.sh

Plot ADC data in ROOT:

> root
root[] .x adc_read.C("adc0.dat",16)
