====== Obsinp Script changes for New Control system ======

The telescope observing interface has been updated to observe with new wide band high frequency receivers. This version of the control interface is referred as the **New Control System** by the Effelsberg team. Below are some details on the changes required in the current observing scripts.

Note that the receivers can also be set up manually as usual. The pull-down menu that displays various receiver versions appears with newer labels. See screenshots towards the end of this page.

=== Snippet from old control system ===

Refer to the obsinp script snippet below. The only change is in the line that refers to the receiver, e.g ''FE:S60mm : VERn 2''. Here ''VERn'' refers to receiver version, and this replaced by a descriptive string in the new control system. In the obsinp graphical interface, the new descriptive string is visible in the pull-down list for each receiver.

Refer to the table below on the precise changes for various receivers.

====== For Timing/Search observations with PSRIX1 (a.k.a ROACH1)  ======

PSRIX1 can process a maximum of 500MHz and is used with P217/P200/S110 receivers. In the list below, only S60/S45/S36 can generate bandwidths >= 500MHz.

====== For the PSRIX2 Instrument ======

PSRIX2 will process a maximum of 8GHz (4GHz at the moment, and 4 more by Jan 2021). For S14/S7, two beams of 4GHz each are processed.
