Key Facts The R&S®DDF255-COR option enables the R&S®DDF255 to correct errors through the use of comparison tables. Especially in mobile DF applications, DF accuracy is often degraded due to vehicle reflections. By applying appropriate error correction, the DF accuracy can be significantly improved. For this purpose, the DF vehicle is exposed to test signals applied in 10° steps from all directions across the entire frequency range. As a result of these measurements, correction tables for each frequency are created and stored in the R&S®DDF255 memory. These tables contain the correct DF value for each measured DF value. By using this approach, many errors are rectified.
