Abstract
The sensitivity of a single station is a crucial performance characteristic of the low-frequency component of the Square Kilometre Array (SKA-Low). In this contribution, the sensitivity of a prototype station of the SKA-Low, the Aperture Array Verification System Version 2 (AAVS2), measured at frequencies 70.3, 110.2, 159.4, 229.7 and 320.3MHz is presented and compared with electromagnetic simulations. The measured sensitivity data are in good agreement with the predictions of electromagnetic simulations, confirming good understanding of the instrument and its accurate representation in the simulations.
