 in the lower left of the GUI opens a log file. Every time a user enters a new

value or clicks on a button in the GUI, the log file updates and shows the actual register address and data value
that was written to the DAC12DL3200, LMK04828, or LMX2592. This log file information can be saved by first
highlighting the register settings to be saved then double clicking inside the log file and selecting
