Open a VNC session to the DBBC you want to configure from the Applications menu on Ops4:
In C:\DBBC_CONF\
are several configuration files for different experiment types. The configurations used for IVS are:
dbbc_config_file_geo.txt
for R1 and R4 geodesydbbc_config_file_geo_16.txt
for AUSTRAL sessionsdbbc_config_file_APSG_CRF.txt
for APSG, CRDS and CRF geodesydbbc_config_file_T2_OHIG.txt
for T2 and OHIGdbbc_config_file_rdv86.txt
for RDV86
The default configuration is kept in dbbc_config_file.txt
and this will be loaded when the server software is started.
(If you want to change the default, Copy (i.e. Do NOT rename) the appropriate file to dbbc_config_file.txt
)
Check to see if a program called DBBC Control net.exe
is running. If not, start it and say “y” when asked if you want to use the default config, otherwise “n”.
Start DBBC Control net.exe
which can be found on the Desktop. If you didn't accept the default config, load the file you want now with the LOAD command. e.g.:
load=dbbc_config_file.geo.txt
Then configure the DBBC with a
reconfig
Configurations will take about 2 minutes.
When the configuration is complete, synchronise the DBBC to the station pps with the following command:
Enter Command: pps_sync
You now need to set up the IF system. The commands to do this depend on the IVS observation and the station.
For R1, R4 and RDV experiments on Hobart and Katherine they should be:
dbbcifa=1,agc,1 dbbcifb=4,agc,4 dbbcifc=2,agc,2 dbbcifd=2,agc,2 dbbcform=geo
For R1, R4 and RDV experiments on Yarragadee they should be:
dbbcifa=1,agc,4 dbbcifb=4,agc,1 dbbcifc=2,agc,2 dbbcifd=2,agc,2 reg=1,17,4 reg=5,17,4 reg=1,19,4 reg=5,19,4
This is because Yg has a non-standard configuration of conditioning modules. CoMo A handles the upper X-band frequencies while CoMo B handles the lower 4. This is the opposite of other sites.
For APSG, CRDS, CRF, OHIG and T2 experiments, they should be:
dbbcifa=1,agc,1 dbbcifb=4,agc,1 dbbcifc=2,agc,2 dbbcifd=2,agc,2 dbbcform=geo
The target values for the total power readings is 56000. this can be checked by the command dbbcif[abcd]. If the levels are too high or low, then adjust the attenuation on the IF box. Note that the levels on IF C (dbbcifc) are a bit low. Don't worry about it.
