How to measure input impedance having negative resistance using VNA??
My VNA(Agilent 8753ES) doesn't seems to plot the area of S11>1.
Is VNA setting same as input impedance having positive resistance?
Or there another VNA setting ??
I want to check impedance in the display right after probing the circuit.
Please let me know.
Thanks.
 

If you increase the scale grater than 1 in Smith Chart display, normally you should see..
