I am using the microwave testbench shown in figure for Standing Wave Ratio measurement.
I have two choices:
one using VSWR Meter,other using CRO .
Can I apply the direct formula (SWR=maximum voltage/minimum voltage) to the square wave
displayed on CRO ?
But according to lab manual (SWR=Square root of maximum voltage/Square root of minimum
voltage). Why we are taking the square root ?
