Hello,

not sure whish board you have. The as3993 is an older version of ST25RU3993.

For ST25RU3993 based boards you could use the ST Reader Suite GUI for ST25RU3993 based boards.
After download the GUI and connect to an ST25RU3993 HPEV board you can generate a frequency list in the Reader settings dialog.
When starting an inventory scan the board then uses the defined frequency list.
The GUI can be downloaded from the following ST website https://www.st.com/en/embedded-software/stsw-st25ru001.html

When trying to develop your own reader application using the ST-UHF SDK library, please have a look to the sample source code.
In the same source code you cam find the usage of the API to setup the reader and define a frequency list.
The SDK including sample source code ca be found on the following ST website https://www.st.com/en/development-tools/stsw-st25ru-sdk.html
