python utilities for DBBC3 monitoring and control

dbbc3

python package and utilities for control and monitoring of the DBBC3 VLBI backend

Documentation

see: https://dbbc3.readthedocs.io/en/latest/

Installation

First you need to install the dbbc3 python package (might require root priviliges)

git clone https://github.com/mpifr-vlbi/dbbc3.git
cd dbbc3/lib
python setup.py install

Alternatively you can do a local installation (current user only):

python setup.py install --user

dbbc3's Issues

FIR filter counts for dbbc3_powerlogger.py rather than whole-IF counts

Based on comments from Sven, it could be better to log the counts from the individual filters rather than the whole-IF counts.

The counts from filters correctly reflect power influenced by IF bandpass shape, spectral channel placement and width.

From the currently logged whole-IF counts it is challenging to reconstruct e.g. GMVA or EHT equivalent per-channel power.

dbbc3 multicast

Hi Helge,
have you tried the multicast feature from the dbbc3? Do you monitor it with a set of Python scripts? At the moment, I am testing that out with one of the dbbc3's in Hobart.
Cheers,

utilities not working due DBBC3Config() changes

Hi! Utilities and the library seem to be out of sync.

For example running setupDBBC3_OCT_D.py leads to

init() takes exactly 2 arguments (1 given)

Probably
config = DBBC3Config()
should now be something like
config = DBBC3Config({ 'mode':'OCT_D', 'majorVersion':str(args.ver) })

I tried the above and a few minor additions to get subsequent errors out of the way (d7e81c5, aed026c; under cluster 'oper' account so these got unexpectedly tagged as your commits) but ran into additional issues. There would be too much to edit at the moment, and you might already have local but not yet pushed changes.

Perhaps you could git-tag the latest still operational version?
