+ | The observatory offers a number of backends for various observing modes. Currently, | ||
+ | the electronic division of the MPIfR is deploying the new "Effelsberg Direct Digitization" (EDD) | ||
+ | system. | ||
+ | |||
+ | Within this, the RF signal is digitized directly in the receiver (without any mixing), and | ||
+ | transported to the backend via Ethernet with high data rate. The signal processing is realized | ||
+ | in software and allows to handle several observing modes (even simultaneously). Currently, | ||
+ | modes are available for continuum/polarimetry, spectroscopy, pulsar observations and VLBI. | ||
+ | |||
+ | For more details, please see [[https://www.ursi.org/proceedings/procGA23/papers/1703.pdf|the paper of Ewan Barr]]. | ||
+ | |||
+ | |||
+ | Still, a number of hardware backends are available. If you are uncertain about | ||
+ | which receiver can be combined with the EDD or the conventional backends, please | ||
+ | do not hesitation to contact us at **eff-support[at]mpifr-bonn.mpg.de**.\\ | ||
