Prerequists R2DBE
- Go through the setup instructions and verify that the system is up and running.
- Make sure that the modules have been initialized, grouped and labeled.
Prerequisits DBBC3
- Go through the system setup procedure for the DBBC3 and verify that the system is in a working condition.
- Make sure that pv-mark6-3 and pv-mark6-4 are up and running
System initialization
Module initialization
ONLY IF REQUIRED: Initialise the modules using the following command. It has to be repeated separately for each Mark6 that has modules that need initialising (example below references the Mark6 using hostname 'recorder1'). This command will erase all existing data on the modules. If you are unsure whether to initialise a set of modules, request guidance from AOC.
backendctl mark6 recorder1 modules 1,2,3,4 init-fresh
if the modules are still in "open" state they must be unmounted before
backendctl mark6 recorder1 group unmount
Repeat for all recorders
Configure the backends (R2DBE only)
backendctl whole configure
Configure the DBBC3
make sure the DBBC3 client is not running
cd /home/oper/rottmann/dbbc3/utilities ./setupDBBC3_OCT_D.py dbbc3 -n 4
Check signal routing
backendctl chain all check routing
Check time synchronization
backendctl chain all check timesync
Adjust power levels (R2DBE)
best: bring antenna to 45 deg elevation
Execute:
r2dbeview
This will bring up the r2dbe-monitor. Adjust the power by setting the BDC attenuators until the distribution matches the grey curve.
Obtain current BDC attenuator levels
backendctl bdc bdc1 get attn
To set the attenuators, e.g.:
backendctl bdc bdc1 set attn sbb_pol1_hi 4
Setting 2Bit Threshold (R2DBE)
backendctl r2dbe all run 2bit-cal all
Check in the r2dme monitor that 2-bit levels are OK (16/33/33/16)
Adjust power levels (DBBC3)
Basically low/high power levels should have been reported by setup script (see above).
In DBBC3 client:
check attenuators, e.g. for board A:
dbbcifa
attenuator settings should be within 20-40, agc should be on
if reported attenuator level is out of range 20-40 the IF power must be decreased/increased.
