STA  files  can  be  used  to  save  and  recall  the  instrument  configuration.

 

They  are  saved  in 

binary format, which is designed to be used by SSA3X instruments, not read by humans. 

2.  TRC(Trace) 

TRC files store the active (visible) trace data and scaling factors that were in place when the 
data was saved. They are saved  in binary format, which is designed to be used by  SSA3X
