thor_arecibo_wbx.py | startdata |
starts datataking (with proper options) |
drf_ram_move.py |
ramcopy |
ram copy program (from ram fs to disc) |

plot_signal.py | plotspc |
plot voltage samples and spectra (to check levels) |

start ram buffer copy to disc. This should be
done before the ram buffer (4gbytes) fills.
|
12 |
Check that the power levels are correct. I
think we get a 14 or 16 bit number out of the usrp.

13 |
monitor that we don't lose data packets over
the ethernet

Stopping datataking
|
switching discs |
|
1 |
stop datataking.. step 14 above |
2 |
delete the uncopied files in /ram |
3 | sudo umount /dev/md0 |
4 |
sudo mdadm --stop /dev/md0 |
5 |
replace the discs
|
other disc
operations |
|
1 |
reassemble a disc array (that was already
written)..
|
2 |
check array status:
