Original question:

TX7332: How do you change the switching frequency of the chip to change the PRF

TX7332: TR switch control

I have programmed all the registers related to the pattern and the T/R switch on/off delays. 
 Will the TR switch be turned on and off with the given delay for every TR_BF_SYNC pulse? TR_EN only needs to give a 200HZ signal according to the requirements of the chip manual to power up the chip?

    Hi,

    The T/R switch turn off will be determined by the delay programmed in the register. The T/R switch on delay is counted either from TR_BF_SYNC edge or the end of pattern depending on the TR_SW_DEL_MODE setting. This will happen on every TR_BF_SYNC. TR_EN can be given as a 200Hz (minimum frequency) signal. If possible, it can be given before every TR_BF_SYNC.

    Thanks and Regards
