| + | 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**.\\ | ||
