How to increase the data throughput on RFSoC 4x2 transmitter

[N-zewge]

Hello,

Thank you for the great resource you have provided on RFSoC.
While running the radio demonstrator (Notebook G) to send a file, the default values
of the mixer settings work fine and an image file is sent successfully. I am now trying to move to
a higher frequency and set the DAC and ADC mixer frequencies to 2400Mhz each.
However, data reception fails in this instance. The main goal is to increase the transmission
data rate to as high a value as possible and try Tx-Rx on larger data files. How would I go about doing that?
Is it possible to set (higher) IQ rates from Python?

Thank you in advance,
