ATCA Bi-static Radar Observing Instructions

Telescope

cacor setup?

DAS

  • Make sure the “8 bit” cable is connected between DAS “DigiOut” board and VSIC
  • Set VSIC to mode (Huygens)
  • Configure DAS using msl_f.pro profile. This gives a 4 MHz band, offset from central ATCA IF frequency by -3 MHz.

Recording

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 copying 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 cetus -p 11111
 

On the receiving machine (cetus 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 -bw1 2.25 -bw2 2.65 -t 60s -online -noplot -dump -command "scp %s yarrie:atca.spec"
 fauto_ipp -noplot -n 4000 -t 10s -online -dump -command "scp %s yarrie:atca_full.spec"'

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

 fauto_ipp -n 4000000 -bw1 2.4 -bw2 2.5 -t 1s -online -dump -radar -noplot -lo 7159 -command "vsib_send -p 50001 -H cetus %s" 

This requires a vsib_recv process running on “cetus”, on port 50001:

 vsib_recv -p 50001
