ATCA Bi-static Radar Observing Instructions


cacor setup?


  • Make sure the “8 bit” cable is connected between DAS “DigiOut” board and VSIC
  • Set VSIC to mode (Huygens)
  • Configure DAS using profile. This gives a 4 MHz band, offset from central ATCA IF frequency by XX MHz.


Record the data using the command:

 vsib_record -m 2 -bits 8 -w 4 -x -o EXPERIMENTNAME -t Xh

Where “X” is the recording time in hours. There is an alias to allow this to be simplified to:

 radarrecord -o EXTERIMENTNAME -t Xh

Realtime copyig of data

`vsib_send` will send .lba data files when they are “complete”, ie the end of 1 1 minute file in normal setup.

On the recorder run (for example):

 vsib_send -online -H draco -p 11111

On the receving machine (draco in the example above)

 vsib_recv -p 11111

The port numbers must match and be allowed through filewall

Realtime spectra

Create realtime spectra to be loaded onto the interactive webpage:

 fauto_ipp -n 80000 -sp1 45000 -sp2 55000 -t 60s -online -noplot -dump -command "scp %s kaputar:atca.spec"

Create realtime spectra in “.rdr” format and copy to the ATNF ftp area (using `vsib_send`):

 fauto_ipp -n 4194304 -sp1 2516582 -sp2 2621440 -t 1s -online -dump -radar -noplot -lo 7159 -command "vsib_send -p 33333 -H draco %s" 

This requires a vsib_recv process running on “draco”, on port 33333:

 vsib_recv -p 33333
