I need the "N4425A Balanced Measurement System software" to be able to use an ATM Microwave ATN-4111A with my HP-8753C VNA.
Another option seems to be the "N1930A Physical Layer Test System software"
I wonder if there is any way to get any of them.
If not, is there any option to use the ATN-4111A test-set, even if only as a 2-port system?. I would hate to own a fancy door stopper :-(
Thanks for your help!
