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_APSG_CRF.txt
for APSG, CRDS and CRF geodesydbbc_config_file_T2_OHIG.txt
for T2 and OHIGdbbc_config_file_rdv86.txt
for RDV86
Next 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 it is, exit it.
Start DBBC Control net.exe
Which can be found on the Desktop.
You will be shown the frequency setup (it should agree with the contents of the config file) and you will be asked if you want to configure the DBBC. Answer with a y
. Configurations will take about 2 minutes. Once complete, start the DBBC Client.exe
software (On the Desktop) and synchronise the DBBC to the station pps with the following command:
Enter Command: pps_sync
One the configuration is complete, you need to set up the IF system. The commands to do this depend on the IVS observation.
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
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.
