======================
Independent Beams Test
======================

Purpose
=======
This test is intended to test if the independent start/stop of beams is functioning as expected.
The station beamformer should be able to independently start/stop beams at any time.
The test is repeated the specified number of iterations, specifically steps 3 to 6.
Default iteration count is 4 iterations.

In one iteration, the beams would look like the following figure:

Methodology
===========
1. Station initialisation.
2. Configuration of 8-beam region_array.
3. Configuration and starting of DAQ.
4. Turning on all 8 beams one by one. Received metrics are compared to expected values (data rate, beam_id, and frequency_id).
5. Turning off all 8 beams one by one. Received metrics are compared to expected values (data rate, beam_id, and frequency_id).
6. Stopping beamformer and DAQ.
7. Beamformer region is reverted to its initial value before the test began.
