Advanced Level

Click on “Advanced” tab on the GUI to bring the advanced panel to the front. On this panel user can write
address and data of any register into the address/data boxes (as shown in

Figure 2

“45” is address and

“4” is data). Press Enter on the key board once data is entered or click “Send All” button on the GUI to
send address and data from the boxes to ADC. The address and data are shown in the display box
located at right side of the panel. In addition, there is group of switches used for output offset functions,
SNRBoost pin overwrite (for ADS58C28), and a group of LEDs used to designate a custom test pattern.
