0.05 m and far range should not have detections outside 0.24 m. Test setup For this test an A121 EVK (XC120 + XE121) was used. To test the presets a corner reflector was moved just outside the edge of the appointed ranges (0.05 m and 0.24 m), see Figure 2. - Page 8 Figure 2: Test setup to test preset ranges, to ensure no detection outside the range. Configurations The configurations below corresponds to the presets in Exploration Tool, see Table 2. © 2023 by Acconeer AB - All rights reserved Page 8 of 13...
