TEST CHART FOR RADIAL RESOLUTION YE157/TE157
The test chart shows a sector star with 180 sectors. One sector corresponds to an angel of 2° and has a black and a white beam.
The center of the sector star shows a white circular area. At the edge of this core the sector width corresponds to a frequency of 10 MHz with reference to the width of the test chart (marked by the gray arrows). Additional white concentric circles mark (on the outer edge) the following frequencies: 8, 6, 5, 4, 3 and 2 MHz.
