====== Pulsar DFB ====== ==== DFB in Spectrometer mode ==== [[pulsarinstruments:dfb:dfbspectro|PDFB4 as Spectrometer]] ==== Current status ==== 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. ==== Aris' DFB Notes ==== A detailed Manual of the DFB timing mode can be found {{:playground:dfbmanual.pdf|here}}. ==== Spin–Velocity Alignment ==== Latest plots: {{:playground:all_psi_histograms.pdf|}} ==== DSPSR and Search mode data ==== 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
