Can I use N9000A CXA signal analyzer to measure devices with 75 ohm impedance?

For N9000A-503 and N9000A-507, an additional 75 ohm RF input connector is available as Option C75.   It is an N-type female connector on the instrument, with a frequency range of 1 MHz to 1.5 GHz. 

Note:  Option C75 is not supported on the N9000A-513 (13.6 GHz) or N9000A-526 (26.5 GHz)
