First appologize my question in the spectrum foprum for a signal generator question.
I am looking for a way to test the PA (power amplifier) without the TRX for GSM standard. What I want to do is to change the biasing to PA with each individual time slot. 

Questions: First is how excatly the trigger output from BNC is synchronized the RF output at the front connector (trigger resolution). Is there any way to adjust the relative time difference between the two outputs.

Secondly, any proved solution to synchronize the RF output to the biasing. Any reference is welcome!
