Station

Overview

This class represents a set of synchronised tiles (TPMs). Contains methods for controlling all tiles.

Python Class & Methods Index

class pyaavs.station.Station(config)

Class representing an AAVS station

add_tile(tile_ip)

Add a new tile to the station :param tile_ip: Tile IP to be added to station

calibrate_station(coefficients, switch_time=2048)

Coefficients is a 3D complex array of the form [antenna, channel, polarization], with each element representing a normalized coefficient, with (1.0, 0.0) the normal, expected response for an ideal antenna. Antenna is the index specifying the antenna within the index (using correlator indexing). Channel is the index specifying the channels at the beamformer output, i.e. considering only those channels actually processed and beam assignments. The polarization index ranges from 0 to 3. 0: X polarization direct element 1: X->Y polarization cross element 2: Y->X polarization cross element 3: Y polarization direct element
