Fig 13. SW_ADC_1_r02: “ADC - Load Registers” page
It is not necessary to have a file that has the whole set of registers listed. The only
restriction is regarding the formatting of the file as given in section 3.3.2.
Note: this page can not be used to download data saved during the comparison process.
To download settings onto device registers, follow the procedure below:
• Browse to select your file (button );
• Click on “Load data” button .
A message on field  and a progress bar will inform about the status of the operation
until message “download done!” is seen. The table  is updated with the current values
downloaded at the fly as can be seen on figure 13.
3.3.5 Tools page
This page allows the user to calculate the coherent frequencies values involved of the
acquisition process. It gives an indication where the 6 first harmonics are located in the
Nyquist zone.
Enter your analog and sampling frequencies in field . Indicate the number of samples
to be acquired , as well as the fixed parameter for the coherency calculation (Fs in our
example above ). Press “UPDATE GRAPH” to look at the frequency plan, it gives also
the real Fin frequency (Refer to appendix A.1 for more details on coherency calculation):
