Key Sequence: Display Setup > Reverse
Average Power: Press this submenu key to have the
sensor measure the average power in the reverse
direction.
Reflection Coefficient: Press this submenu key to
measure the reflection coefficient:
Reflected Power / Forward Power
Return Loss: Press this submenu key to measure
return loss, which is the measurement in dB of reflected
energy caused by impedance mismatch. May also be
referred to as S11.
VSWR: Press this submenu key to measure Voltage
Standing Wave Ratio (VSWR), which is another
measurement of reflected energy caused by impedance
mismatch. Expressed as a ratio of X:1. VSWR
measures the voltage peaks and valleys.
