PDFB4 as Spectrometer

The ATNF Pulsar DFB related stuff are in this page. Currently supported are the timing and search modes. The baseband mode is not operational due to a firmware issue and is being discussed with ATNF.

A detailed Manual of the DFB timing mode can be found here.

DSPSR/PSRCHIVE can be used to fold and dedisperse search mode data from the DFB. Here is a short recipe:

• Copy data to pulsar server.
• Fold: dspsr -N 2021 -k Effelsberg -L 10 Srch_file.fits

In the above, -L is to create 10-second sub-ints, -N is the name of pulsar, -k is TEMPO site information.

• Once this is done, add all 10-sec subints: psradd -f add.ar 2010*.ar
• Now plot and view:

   freq-phase plots: pav -GTp -d add.ar
   
   time-phase plots: pav -YFp add.ar
   
 * Examples are in pulsar server: pulsar@134.104.64.64:/data1/ramesh/2111
