I've got a cable with an N connector on one end and an SMA on the other. I want to measure the cable on an E5071C network analyzer. My problem is how to calibrate for an N of one port and SMA on the other. Is it possible to define my own cal kit with N standards, from the HP85032B kit, on one port and 3.5mm standards, from the 85033E, on the other port? And then use an SMA-N adapter as an unknown thru?
