Set the RF to a fixed transmission frequency

Is there any software to set the fixed frequency of RF transmission on NXP website?

Or a test software that sets a fixed RF transmission frequency.

I'm currently developing a project for TPMS, The chip used is FXTH87E.

Now we are testing the RF sending data, I'm going to set the RF fixed frequency to 433.92MHz.

I used the TPMS 87E WheelLoc sample project. Above is some code from the function RF init().

I've done this multiple times, The center frequency signal captured during the test could not be accurate to 433.92MHz.

Do I need to set other parameters for RF transmission frequency?
