5.5 Loading the DC Offset Values

The fourth configuration file contains the register writes to load the DC offsets values externally. This file requires user modifications to load the values recorded read at the address in the previous section.

  1. Modify the DC Offset Values
    1. Open the pre-load_write.cfg file
    2. Modify the file with the values recorded from the addresses in Table 5-1
    GUID-20230502-SS0I-Z6SP-T8T7-ZVCWQKTVLZ4Z-low.png Figure 5-4 Modified Configuration File with Values
  2. Load DC Offset Values: pre-load_write.cfg (load into the GUI)
    1. Enables the external offset correction load option
    2. Sets the correct page to load the offset correction values externally
    3. Contains the modified values from Figure 5-4.
