+**Comments:**
+  * The system delivers two basebands, 1.3-2.6 GHz and 3.0-6.0 GHz. Currently, it is only possible to record both bands in parallel for pulsar observations (timing and search mode), but not yet for continuum or spectroscopic observations.
+  * Usable / useful continuum bands are e.g. 1.405-1.415 GHz, 1.66-1.67 GHz, 4.7-5.0 GHz, 5.3-5.6 GHz.
