I have a fsh 6 spectrum analyser . I wanted to produce a picture out of it to send to a manufacturer so i bought a philips 9080 optical coupler cable with a serial (rs232) plug on it a work mate has a laptop with 232 plug on it so seems logical to pair them up and away we go !!!! no way in hell cant get the spect to see lappy or other way around mate is tearing his hair out . Anyone had any experience with these animals help really needed tia don
