There are six different gain tables included with the FMCOMMS driver package. Three are full gain tables and three are split gain tables. Each of the three is optimized for a particular LO frequency range. The gain control portion of the user guide contains more information about gain table types and how they are used.
The tables included with the driver package are in a format that is difficult to manipulate if customers want to create customized gain tables. The zip file in this FAQ contains the same six gain tables that are in the software but in .csv format.
