•

Measurement Results panel
–

Power

: Shows the reflected power measurement result in a numeric form. The 

reflected power measurement is performed by ST25RU3993.

–

Angle

: Shows the phase of the reflected power relative to the local oscillator 

signal.

–

I

: ADC results for the in-phase component of the reflected power measured by 

ST25RU3993

–

Q

: ADC results for the quadrature component of the reflected power measured by 

ST25RU3993
