A Pulsar Observation System with a Mark 5B Recording System and a DSPSR Software

Some observations of PSR J0332+5434 and PSR J0835-4510 were carried out by the radio astronomy group in the YNAO(Yunnan Observatories) using pulsar observation system based on a DBBC(Digital Base Band Converter) backend data acquisition system, a Mark 5B recording system, and the DSPSR(Digital Signal Processing for Pulsars) software. The RCP (Right Circular Polarization) S-band was selected for the observations. We used 2 channels with a total bandwidth of 4MHz, 4 channels with a total bandwidth of 16MHz, and 8 channels with a total bandwidth of 128MHz. The DSPSR was used for the coherent dedispersion of the data with the results in the PSRFITS format if needed. The entire pulsar observation system has better data processing methods, higher calculation efficiency, and more adaptability to data as compared to an old system only with DBBC and Mark 5B.
