Not sure what you mean by more of a service monitor.... That is what mine
is. Only things mine doesn't have are the spectrum analyzer and a sweap
generater. I'm surprised it doesn't have a serial port. Mine is 12 years
old and it came with one. How high in frequency does this one goe? Mine
only goes to 999 mhz.
