A LED shows if the channel is ON (active - green LED) or OFF (not active - red LED)
and if the same channel is ready (ready to receive gain, offset or phase orders - green
LED) or busy (not ready to receive new calibration orders - red LED).
Figure 4-38. Channel Selection
Once a channel has been selected, gain/offset/phase of this channel can be adjusted:
 you first need to enter the desired value for the gain/offset/phase thanks to the cursor;
 if you need to retrieve the old value of the gain/offset/phase click CANCEL;
 then you should WRITE this value to the internal registers by clicking on the WRITE
button,
 if several adjustments are needed (gain AND offset AND phase), then select each
value and then click on the respective WRITE buttons;
 once all adjustments are made via the WRITE buttons, orders to the ADC SPI can be
sent using the SEND button;
 the calibration is successful if the internal gain/offset/phase boxes display the entered
values.
If a new value for the gain/offset/phase has been entered by mistake, it is possible to
retrieve the initial value by pushing the CANCEL button.
Figure 4-39. Cancel Button
In the following example, it can be seen that the internal Gain register is set to 0.059 and
that the user wants the phase to be set to -15. In the second picture, the WRITE and
SEND buttons have been pushed and the internal register shows the new entered value
for the phase.
